To test predictions of learned helplessness theory and

attribution theory, depressed and nondepressed subjects were

exposed to a word-association task in a skill, chance, or

no-instructional-set condition. Subjects were asked to make

attributions of success and failure to four factors--ability,

effort, task difficulty, and luck--and rate expectancy of

success.

The predictions of both theories were only partially

confirmed. Difficulties relating to the experimental design

may account for the failure of nondepressed/skill subjects

to show greater expectancy change. As predicted, all sub-

jects in the chance condition displayed similar expectancy

changes. Also as predicted, nondepressed subjects did not

rate effort as being the least influential factor. Depressed

subjects, however, rated all factors equivalently, instead of

rating effort least influential.

LEARNED HELPLESSNESS, ATTRIBUTION,

AND CLINICAL DEPRESSION

Seligman and his co-workers, on the basis of much

empirical research, have postulated a general theory which

holds that organisms are sensitive and responsive to con-

tingencies of reinforcement in which the probability of

reinforcement given a particular response equals the

probability of reinforcement given the absence of that

response (Maier & Seligman, 1976; Seligman, Maier, &

Solomon, 1971). In such a contingency situation, the

reinforcement or outcome is independent of the particular

response. In the case where the reinforcement or outcome

is independent of all emitted responses, it is defined as

being uncontrollable. Seligman et al., (1971) suggest

that organisms exposed to uncontrollable outcomes can

become aware of this fact, develop a generalized expec-

tancy of lack of control, and display the behavioral

deficits which characterize "learned helplessness" in

situations where control is objectively possible. Maier

and Seligman (1976) suggest that the behavioral deficits

can be categorized as being motivational, cognitive, or

emotional deficits.

1. The motivation to respond appears to be greatly

diminished. For example, dogs exposed to uncontrollable

electric shock subsequently fail to respond in a shuttlebox

(Overmeier & Seligman, 1967), and students exposed to uncon-

trollable aversive noise later fail to escape it more

frequently than nonexposed students or students exposed to

noise which they could escape (Hiroto, 1974).

2. A cognitive deficit is manifested when a response

is made which successfully produces the desired outcome, yet

the subject has difficulty learning that the response and

the outcome are related. Thus, helpless dogs that success-

fully escape shock on one or more trials by jumping a

shuttlebox barrier are likely to revert to passively accept-

ing shock on later trials (Overmeier & Seligman, 1967).

Similarly, helpless students require significantly more

trials to discover an anagram pattern than do nonhelpless

students (Hiroto & Seligman, 1975).

3. Emotional disturbance may be displayed in some cases.

Seligman (1975) cites a number of animal studies which indi-

cate that exposure to uncontrollable aversive stimulation

results in physiological and behavioral changes indicative

of increased emotionality. These changes include increased

susceptibility to develop stomach ulcers, decreased food

intake, increased defecation, and the breakdown of a well-

learned appetitive discrimination. Gatchel, Paulus, and

Maples (1975) found that students pretreated with an uncon-

trollable aversive noise recorded greater depression, anxiety,

and hostility scores on an adjective check list than subjects

pretreated with an escapable noise.

Learned helplessness, as an empirical phenomenon, has

been demonstrated to occur in a variety of species (Seligman,

1975). Of primary importance to the present research, how-

ever, are the human helplessness studies. These have been

of two types.

The first type of study attempts to induce helplessness

in subjects by exposing them to uncontrollable aversive

stimulation. The design of the animal studies are typically

followed, so that there are three groups of subjects. The

first group (inescapable) is given pretreatment with ines-

capable (uncontrollable) aversive stimulation such as a

loud tone (Hiroto, 1975), electric shock (Thornton & Jacobs,

1971), or insolvable problems (Hiroto & Seligman, 1975).

A second group (escapable) is given pretreatment with aver-

sive stimulation which is escapable (controllable). A

final group (no-pretreatment) is given no pretreatment.

All three groups are then tested on a different task such

as performing in a human shuttlebox analogue situation

(Hiroto, 1974), or decoding anagrams (Hiroto & Seligman,

1975). The studies generally have found that the inescap-

able group performs significantly worse on the test task

than the escapable group or the no-pretreatment group.

The latter two groups typically do not differ significantly

from one another, supporting Seligman's (1975) assertion

that it is exposure to uncontrollability, not merely to

aversive stimulation, which results in helplessness.

Page 9: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

4

The second type of experiment is designed to test the

speculation that learned helplessness might serve as a

model of reactive depression (Miller & Seligman, 1973).

Seligman (1974) thoroughly reviewed the evidence linking

depression in humans with learned helplessness in animals.

His conclusions were that depressed and helpless subjects

were both characterized by passivity (slowness or failure

to initiate responses), retarded learning about control

over trauma, weight loss, and anorexia (loss of appetite).

Both phenomena may show a time course (i.e., dissipate

over time) and may be related to decreased levels of brain

norepinephrine. Seligman notes that his findings, although

suggestive, are hardly conclusive evidence that one phenom-

enon (animal helplessness) is a model of the other (reactive

depression). He lists four lines of evidence which appear

to be relevant to further investigation of this speculation:

(a) behavioral and physiological symptoms, (b) etiology,

(c) cure, and (d) prevention.

Miller and Seligman (1973) performed a study which

examined a set of predictions concerning the similarity of

behavioral symptoms of depression and learned helplessness.

Seligman, Maier, and Solomon (1971) argued that the symptoms

characteristic of learned helplessness in animals were the

result of the animals' learning that the aversive stimula-

tion was independent of voluntary responding. Miller and

Seligman (1973) reasoned that if learned helplessness were

Page 10: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

5

a valid model of reactive depression, then depressives should

tend to view outcomes (or reinforcement) as being response-

independent. Assuming that helplessness and depression

occurred in varying degrees of severity, they postulated that

depressed persons, because of their belief that they lack the

ability to change their environment, would tend to view

response-dependent tasks as being more response-independent

than nondepressed persons, who should accurately perceive

response-outcome relationships.

Miller and Seligman (1973) tested their predictions by

having depressed and nondepressed college students perform

two tasks-a "skill" task and a "chance" task. These authors

noted that previous research in the area of locus of control

had demonstrated that subjects' expectancies for future suc-

cess on a task were related to reinforcement on previous

trials and to instructional set, Specifically, when a sub-

ject perceived reinforcement as being response-dependent

(ire,, the subject was told that his skill determined the

outcome) , reinforcement had a greater effect in influencing

expectancies of success than when reinforcement was viewed

as beiLng response-independent (i.e., the subject was told

that chance determined the outcome). Miller and Seligman

(1973) noted that chance-determined reinforcement, strictly

speaking, does not meet Seligman's et al. (1971) definition

of response-independence in that the subject can fail to

respond or can respond in a manner inappropriate to the task.

Page 11: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

6

If experimental-demand characteristics limit the subject's

responses to those which are task-appropriate, then,

. . . in the sense that conditional probability of

reinforcement given any available response equals

the conditional probability of reinforcement given

any other available response, chance-determined

reinforcement is response-independent. (p. 63)

Noting the apparent similarity of the hleplessness

concept of learning (that reinforcement and responding are

independent) and Rotter's concpet of locus of control, Miller

and Seligman (1973) subdivided their groups along the dimen-

sion of high-versus-low externality. Subjects who perceived

reinforcement as being under external control were placed in

the high-external group, while subjects who viewed reinforce-

ment as being under their own control were placed in the low-

external group. Each subject was presented with a "chance"

and "skill" task to perform. Regardless of the instructional

set, reinforcement was actually controlled by the experimenter

so that all subjects received the same pattern of reinforce-

ment. Before each trial, the subjects were asked to rate

their expectancy for success for that trial on an 11-point

scale, Change in the expectancy of success was the primary

experimental measure.

Although the high-versus-low analysis did not reveal any

significant differences between groups, the depressed-versus-

Page 12: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

7

nondepressed analysis produced significant results in 13 of

the 15 statistical tests. Depressed subjects showed less

change in expectancy of success following reinforcement in

the skill task than did nondepressed subjects, while

depressed and nondepressed subjects did not differ in expec-

tancy change following reinforcement in the chance task.

Nondepressed subjects in the skill task showed greater

expectancy changes than nondepressed subjects in the chance

task or than depressed subjects in the skill task. Since

the responses of depressed subjects in both the skill and

chance situations were similar, Miller and Seligman (1973)

concluded that depressed subjects viewed both situations as

involving response-independent reinforcement. The authors

suggest that the failure of the high-versus-low analysis

to produce significant results may have been due to the

inadequecies of the scale used to determine externality.

Using another scale, Hiroto (1974) was able to demonstrate

that the responses of externals paralleled the responses

of helpless subjects on a test task.

Other experiments are relevant to the present discus-

sion. Miller, Seligman, and Kurlander (1974) performed a

replication of the Miller and Seligman (1973) study, using

a single ambiguous task and varying the instructions to

produce a skill or chance set. This change was made to

ensure that nothing except a difference in reinforcement

contingencies was operative in producing the differences

Page 13: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

8

across tasks. Miller et al. (1974) also collected evidence

which indicated that the reported differences in expectancy

change were related to depression but not to anxiety.

Miller (1975) demonstrated that the performance of depressed

students on an anagram-decoding task was similar to the per-

formance of helpless students (those exposed to inescapable

aversive noise). Miller and Seligman (1975) found that

depressed students and students exposed to inescapable aver-

sive noise tended to exhibit similar changes in expectancy

of success following reinforcement in both chance and skill

tasks.

In a related study, Klein and Seligman (1976) demon-

strated that the administration of a series of solvable

discrimination problems reversed the performance deficits

of both depressed and helpless students. All four studies

produced evidence generally supportive of the learned help-

lessness model of reactive depression. It should be noted,

however, that none of the studies cited above included a

population which could be properly labelled "clinically

depressed." In each of these studies, scores on the Beck

Depression Inventory (BDI) (Beck, Ward, Mendelson, Mock, &

Erbaugh, 1961) were used to assign subjects to the appro-

priate group, with subjects scoring at 8 or below entering

the nondepressed group and those scoring at 9 or above

entering the depressed group. The mean score of Beck's

(1970b) mildly depressed group was 18.7. Miller and Seligman

Page 14: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

9

(1973) noted that no subject in their study had a score

equal to or greater than the mean (25.4) for Beck's (1970b)

moderately depressed group. In each study, the various

authors commented on the mild level of depression displayed

by their subjects and recommended further experimentation

with clinically depressed subjects.

Dweck and Repucci (1973) linked the learned helpless-

ness phenomenon to "reinforcement responsibility" which

refers to "the extent to which one perceives oneself as a

causal agent in behavior-outcome sequences" (p. 108).

Analyzing the area of outcome control in terms of attribu-

tion theory, Dweck (1975) hypothesized that the performance

deficits of helplessness would be related to a person's

attribution of causality in a failure situation.

Weiner (1974) has suggested that people typically make

attributions of causality in achievement motivation situa-

tions to four factors (ability, effort, task difficulty,

and luck). He notes that these four factors can be divided

into two dimensions: locus of control (each factor viewed

as being under internal or external control) and stability

(each factor viewed as being fixed or variable). Ability

would thus be seen by most people as being a fixed, internal

factor, while luck would be viewed as being a variable,

external factor. Table 1 illustrates the relationship.

10

Table 1

StabilityInternal External

Fixed Ability Task Difficulty

Variable Effort Luck

Weiner (1974) suggests that changes in the stability dimen-

sion influence later expectations of success and failure

(with greater change in expectancy occurring with fixed

factors), while changes in the locus of control dimension

influence affective responses (with a stronger affective

response occurring with internal attributions).

According to Seligman (1975), it is the subject's

expectation of a lack of control that maintains helplessness

in situations where the subjects can objectively control the

outcomes. Dweck and Repucci (1973) found that subjects who

were least helpless tended to make more attributions to

internal factors in general than the more helpless subjects.

In addition, when making internal attributions the least

helpless subjects were more likely to make attributions to

effort. It can readily be seen that the subjects should

experience the greatest subjective feeling of control when

Page 16: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

11

effort attributions are made. This is because one's ability

is viewed as being relatively stable and unchanging in a

given situation, while external factors are by definition

outside the realm of one's direct control. Effort, there-

fore, represents the only factor readily under the control

of the individual because it is variable and internal.

Dweck and Repucci (1973) found support for their

hypotheses that persons who were helpless would: (a) accept

less personal responsibility for success and failure (i.e.,

make fewer internal attributions); and (b) display a greater

tendency to view outcomes, when attributed internally, as

due to the presence or absence of ability. In a later study,

Dweck (1975) was-able to reduce the amount of helpless

behavior her subjects displayed by training them to attri-

bute failure to the variable, internal factor of effort,

thus enhancing their subjective feeling of control over

outcomes. Dweck's helpless subjects were school children

who, following failure in solving arithmetic problems,

tended to give up and stop responding although adequately

motivated to perform and having the ability to do so.

Klein, Fencil-Morse, and Seligman (1976) have conducted

an experiment which also attempted to link the concept of

helplessness with those of attribution theory. These

authors induced helplessness in mildly depressed and non-

depressed college students by exposing them to unsolvable

Page 17: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

12

discrimination problems. The students were given instruc-

tions which were designed to manipulate their attributions

of failure to either task difficulty or ability. For

depressed subjects, attributions of failure to task diffi-

culty resulted in amelioration of the effects of helpless-

ness induction. Attributional set had no influence on the

responses of nondepressed students, however, causing the

authors to speculate that the two groups interpreted the

task differently, possibly in terms of its importance to

them.

Although at first glance there appears to be little

similarity between Seligman' s experiments concerning depres-

sion in college students and Dweck's study of academic

behavior in elementary-school children, the learned help-

lessness model has been offered as an explanation of the

behavior in both cases. In addition, both the Dweck (1975)

and Klein et al, (1976) studies investigated the relation-

ship between helplessness and attributions of failure. The

Dweck (1975) study demonstrated the therapeutic effects of

changing attributions of failure from ability (a fixed,

internal factor), or task difficulty (a fixed, external fac-

tor), In each case, the authors have studied only one of

Weinerls (1974) two dimensions--locus of control (Klein et

al., 1976) or stability (Dweck, 1975).

The present study is an attempt to discover what rela-

tionship exists between depression and attribution when

Page 18: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

13

both dimensions are considered. The outcome of this study

should suggest some implications for therapy. If it can

be demonstrated that clinically depressed persons report

attributions which are different from those of nondepressed

persons, a possible therapeutic intervention might involve

changing these attributions, since previous research has

suggested that this procedure alleviates helplessness in

mildly depressed subjects and academically helpless children.

The attributions made by nondepressed persons should provide

the guidelines for the most effective direction for changing--

that is, across the dimension of locus of control or of

stability. The idea that a change in cognitions can result

in a change in feelings or behavior has been suggested many

times before (Beck, 1970a; Ellis & Harper, 1977), but attri-

bution theory may help expand the available treatment

strategies.

All of the previously published studies empirically

linking learned helplessness with depression have not

included a clinically depressed population. The present

study is an attempt to expand on earlier studies by produc-

ing data that allows evaluation of the validity of the

learned helplessness model for individuals who are clinically

depressed, and demonstrating that attribution theory provides

a conceptual framework within which these data can be organ-

ized and explained.

14

The specific hypotheses to be tested are as follows.

1. Depressed subjects should view task outcome as being

more response-independent than nondepressed subjects in the

skill condition, but both groups should view task outcome

as being relatively more response-independent in the chance

condition. Therefore, the depressed group should show less

change in expectancy of success following each trial in the

skill condition, but the two groups should not differ in

change of expectancy of success for the chance condition.

2. Depressed subjects should accept less personal

responsibility for success and failure; therefore, the

depressed group should rate the variable, internal factor

of effort as being the least influential factor in determin-

ing success and failure in the no-instructional-set condition.

3. Nondepressed subjects should accept more personal

responsibility for success and failure; therefore, the non-

depressed group should not rate the variable, internal factor

of effort as being the least influential factor in determin-

ing success and failure in the no-instructional-set condition.

Method

Subjects

Subjects in this study were 49 persons entering the

Evaluation and Therapy Service, a division of the Department

of Adult Services, of a community mental health center.

Clients between the ages of 9 and 60, nonpsychotic, and

judged to need short-term therapy for nonalcohol-related

Page 20: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

15

problems usually enter this service. For a period of 11

weeks, eligible persons seen for admissions were informed

of the research study and asked to participate in it.

There are nine separate services in the mental health

center; therefore, admissions workers were instructed to

inform only those clients likely to enter the Evaluation and

Therapy Service (ETS) of the research study and ask for their

participation. Admissions workers were further instructed

to give each client a priority rating of 1, 2, or 3, which

correspond roughly to a maximum delay, in weeks, before

scheduling of an initial therapy appointment. Clients in

immediate need of services (a priority rating of 1) were not

accepted for this study. Final determination of the appro-

priate service and priority rating was not actually made

until a staff conference on the day after admissions, in

accordance with mental health center policy. Several clients

were, therefore, admitted into ETS without being asked to

participate in the research. Subsequent attempts to contact

them before initial therapy were usually unsuccessful. In

all, 10 clients either refused to participate or could not

be contacted, and 23 clients agreed to participate but failed

to show for their appointment.

Consenting clients were asked to complete the Beck

Depression Inventory (BDI) immediately following the admis-

sion interview. Based on their BDI scores, clients were

assigned to a depressed or nondepressed group. A clinically

Page 21: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

16

derived dividing score was used to assign clients to one of

the two groups. This dividing score (19) represents the

median initial BDI score for persons opened and terminated

in an adult outpatient service of a community mental health

center for the program year 1975-1976. Clients scoring at

or above 19 were assigned to the depressed group; clients

scoring below 19 entered the nondepressed group. The divid-

ing score falls slightly above the mean score (18.7) for

Beck's (1970b) mildly depressed group. Most of the subjects

classed as depressed in previous studies would be classed as

nondepressed using this criterion.

Recruitment continued until 24 clients had been tested

in each group. During the course of the testing, one

depressed client became very upset and agitated, and was

released from the study. The final sample consisted of 48

subjects.

The clients in each of the two groups were assigned to

one of three conditions--skill, chance, or no-instructional-

set--on the basis of a predetermined random schedule so there

were equal numbers in each condition. The experimental design

is illustrated in Appendix A. All clients accepted into the

experiment were seen individually for one hour by the experi-

menter within two weeks of the admissions interview, and

before their initial therapy session.

Apparatus

Word-Association Task. The same task was used for the

skill, chance, and no-instructional-set conditions, and is

similar to one used by Wener and Rehm (1975) to covertly

control rate of reinforcement. A 3 X 5 filing card was

prepared for each of 20 stimulus words (Appendix B). In

order to reduce the likelihood of the subjects' becoming

aware of the experimental manipulation, a relatively small

number of cards were used. Words were selected which had

associates with the highest overall probability of occurring

(both associates had a probability of .17 or greater) and

which did not differ greatly in probability (less than .05

difference).

The primary experimental measures were the expectancy

and attributional ratings. Other measures were also used

to gather information of relevance to the study.

IPAT Anxiety Scale. Miller et al. (1975) have pre-

sented evidence to indicate that the tendency to perceive

reinforcement as being response-independent is unique to

depression and not to psychopathology in general. They

were able to demonstrate that variation in the experimental

measures was correlated with depression but not with anxiety.

The IPAT Anxiety Scale (King, Scheier, & Cattell, 1976) was

administered to subjects in this study to allow a similar

analysis to be made.

Gambrill-RicheyAssertion Inventory. Seligman (1975)

and Lazarus (1968) have suggested the use of assertion train-

ing as a possible therapeutic technique in the treatment of

depression. Gambrill and Richey's (1975) Assertion Inven-

tory was administered to determine how assertiveness relates

to the experimental measure.

Perceived Control Response Scale (PCRS). Maier and

Seligman (1976) suggest that perceived lack of control is

the relevant variable in the development of helplessness.

The Perceived Control Response Scale (PCRS) was developed

for this study to examine the subjects' feelings of control

over outcomes in situations outside of the test task, thus

providing information about the generality of helplessness.

The PCRS (Appendix C) asks the subject to rate on an

lb-point scale (from "no influence" to "complete influence")

the amount of influence they feel they have in controlling

outcomes for each of the 6 areas: (a) health, (b) financial

matters; (c) household matters; (d) situation at work or at

school; (e) relationship with spouse (boyfriend/girlfriend);

and (f) relationship with friends.

Procedure

Immediately following their admissions interview, the

subjects were asked to complete the Beck Depression Inven-

tory (BDI), The instructions had been modified slightly to

allow the inventory to be self-administered.

At the beginning of the research session, the subjects

were administered the IPAT Anxiety Scale (Today Form), the

Gambrill-Richey Assertion Inventory, and the Perceived Con-

trol Response Scale,

Page 24: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

19

Subjects were then presented with the word-association

task. All subjects were given the following instructions

(adapted from Wener & Rehm, 1975).

In front of you is a book of twenty cards. Each

card has one word written on it. I would like

you to say aloud the word which most people would

associate to the word on the card. It is import-

ant to remember that the word will not necessarily

be the one which you would associate with it, but

rather the one which most people would associate

to it, For example, if the word on the card is

"needle," your correct response would be "thread,"

since most people associate "thread" with "needle."

From tests given to over 1500 people, we have

determined the most common responses to each of

the words, Your answer will be compared to the

answer given by the majority of the people, and

you will be told if your answer is correct or

incorrect,

The following additional instructions were given to

those subjects in the skill condition.

Some people do well and others poorly, depending

on their skill. Thus, your score is determined

by your skill,

Subjects in the chance condition were given the follow-

ing instructions instead,

Page 25: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

20

No one gives consistently correct answers, and

the test does not, therefore, differentiate between

people who have different amounts of skill. Thus,

your score is determined by chance.

Subjects in the no-instructional-set condition were not

given any additional instructions.

The subjects were asked to estimate their probability

of success before each trial using a scale from 0 (success

totally unlikely) to 10 (success completely likely). After

reading the task instructions, the experimenter read the

instructions for estimating the probability of success for

the first trial to all subjects.

Before each trial, I would like you to estimate

your likelihood of success in naming the correct

word. Use the scale in front of you to estimate

your degree of certainty of success. If you are

fairly certain that you will succeed, rate your-

self with a high number such as 9 or 10. If

moderately certain, use a number near the middle

of the scale, such as 4, 5, or 6. If you are

fairly certain that you will not succeed, rate

yourself with a low number, such as 0 or 1. You

may use any number of the scale from 0 to 10

inclusive. It is important that you select your

estimates carefully and that they correspond

Page 26: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

21

closely with how certain you really are. They

should be an accurate description of the degree

to which you feel that you will or will not

succeed. Now, make an estimate on the 0 to 10

scale as to what you think your likelihood is

of succeeding on the first trial.

The experimenter actually controlled success or failure

in order to insure that all subjects had the same pattern of

reinforcement. The experimenter simply told each subject

that he was correct or incorrect after each trial, following

the same randomly determined 50% pattern of reinforcement

for all subjects. The task appeared to be sufficiently dif-

ficult so that the subjects did not question the results

(Wener & Rehm, 1975).

Following each trial, the subjects were asked to rate

on an ll-point scale (from "no influence" to "a lot of influ-

ence") the degree to which the outcome was influenced by

each of four factors: ability, effort, task difficulty, and

luck. Two written scales were used. They are included as

Appendices D and E. One scale was presented after "correct"

responses, and the other after "incorrect" responses. The

only differences in the two scales were the labels provided

for each factor. The "correct" response scale utilized a

positive statement of each factor (e.g., task easiness, good

luck), while the "incorrect" response scale utilized a nega-

tive statement (e.g., task difficulty, bad luck). The

Page 27: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

22

differentiation was made only to make the scales more under-

standable to the subjects. The following instructions were

given for these scales.

Previous research has shown that success or fail-

ure on a test like this is usually explained by

four factors--the amount of ability you have, the

amount of effort you expend, the difficulty of

the test, and the kind of luck you have. On the

sheet in front of you, rate the amount of influ-

ence each of these factors had in causing your

success or failure. If you feel that a particu-

lar factor had a great deal of influence, you

would select a high number such as 9 or 10. If

you feel that a factor had no influence, you

would select a low number such as 0 or 1. You

may use any number on the scale to make your

rating. Be sure to rate all four factors. Do

you have any questions?

When all 20 cards had been presented, the subjects were

then asked to answer three questions. Each client was first

told that he was correct on 50% of the word-association trials

and was asked to rate on an 11-point scale how well he did in

comparison to the "average" person on this test. Second, the

clients were asked to rate on an 11-point scale the diffi-

culty of the word-association task. Last, the clients were

asked to rate the extent to which the four attributional

Page 28: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

23

factors served as a sufficient explanation for their success

or failure, using an 11-point scale (Appendix F). Finally,

each client was debriefed and thanked for his participation.

Results

The experimental analyses failed to produce evidence

completely supportive of learned helplessness and attribution

theory predictions. Each of the dependent variables relating

to the hypotheses will be discussed separately. A listing of

group means and standard deviations is provided for each var-

iable. A summary of the analysis of variance data for each

variable is included in Appendix G.

Initial. Expectancy

Depressed subjects displayed significantly lower expec-

tancies of success than did nondepressed subjects, F (1, 42) =

13.19, p < .01. There were no significant tasks-effect or

interaction. Initial expectancy was significantly and nega-

tively correlated with BDI scores, r (46) = -.49, p< .01,

and IPAT Anxiety Scale scores, r (46) = -.47, p < .01. Means

and standard deviations of expectancy ratings and changes in

expectancy are presented in Table 2.

Expectancy Change

The first hypothesis predicted that depressed subjects

would show less change in expectancy of success following

each trial in the skill condition than would nondepressed

subjects, but that both depressed and nondepressed subjects

would not differ in change in expectancy of success for the

chance condition. The predicted interaction failed to occur.

Following Miller and Seligman's (1973) procedure, total

expectancy change was computed by summing the absolute value

of the difference in expectancies between one trial and the

next for all trials in which expectancy increased following

success and decreased following failure.

Depression X tasks analyses of variance conducted for

total change in expectancy and change in expectancy following

failure revealed no main or interaction effects. Depressed

and nondepressed subjects did differ significantly in change

in expectancy following success, with depressed subjects

recording greater changes in expectancy, F (1, 42) = 3.23,

p < .05. Contrary to prediction, there were no task-specific

changes in expectancy for any expectancy-change measure.

Attributions

The second hypothesis predicted that depressed subjects

would rate effort as being the least influential factor in

determining success and failure in the no-instructional-set

condition. Different rating scales were used following suc-

cess and failure; therefore, the responses were analyzed by

means of two series of planned orthogonal comparisons. The

results indicate that depressed subjects saw ability, effort,

task difficulty, and luck as being equally influential fol-

lowing success and also following failure. Their ratings

of effort did not differ significantly from their ratings

Page 31: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

26

of ability, task difficulty, and luck, thus failing to sup-

port the hypothesis. Means and standard deviations for the

no-instructional-set groups are presented in Table 3.

The third hypothesis predicted that nondepressed sub-

jects would not rate effort as being the least influential

factor in determining success and failure in the no-

instructional-set condition, Nondepressed subjects rated

luck the least influential factor, thus supporting the

hypothesis. Planned orthogonal comparisons of ratings after

Page 32: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

27

success and after failure demonstrate that the ratings of

luck differed significantly from the ratings of effort,

F (1, 28) = 11.97, p < .01, after success; F (1, 28) = 7.25,

p < .025, after failure. The ratings of ability and task

difficulty did not differ significantly from those of effort

in both conditions,

Post hoc t-tests were conducted to determine if

depressed and nondepressed subjects tend to respond differ-

ently in terms of absolute score values for the two internal

factors of ability and effort, Attribution theory suggests

that individual control over outcomes is most possible given

attributions to these two factors. All t's were nonsignifi-

cant, indicating that depressed and nondepressed subjects

tend to view the influence of ability and effort on perform-

ance similarly.,

Beck Depression Inventory

The depressed and nondepressed groups, as expected,

proved to be significantly different from one another in

terms of degree of depression, F (1, 42) = 74.60, p < .01.

The skill, chance, and no-instructional-set groups did not

differ significantly from one another. Beck Depression

inventory scores were significantly correlated with two

other dependent measures--IPAT Anxiety Scale scores, r (46)

=;,,58f g < .01, and Initial Expectancy, r (46) -,49,

P <,01, Greater depression is thus associated with greater

anxiety and decreased initial expectancy of success, Table 4

presents the means and standard deviations for each of the

tests administered.

Anxiety

Depression and anxiety appear to be significantly related.

Depressed subjects recorded significantly higher scores on

the IPAT Anxiety Scale, F (1, 42) = 16.17, p < .01, indicat-

ing that they experience greater anxiety than nondepressed

subjects. There were no other significant main or interac-

tion effects. As noted earlier, IPAT Anxiety Scale scores

correlated significantly with scores on the Beck Depression

Inventory, r (46) = .57, p < .01.

Assertiveness

The Gambrill-Richey Assertion Inventory was administered

to investigate what relationship, if any, existed between

assertiveness and depression. Analyses of variance (Depres-

sion X Tasks) were conducted for both scales of the Gambrill-

Richey Assertion Inventory. None of the analyses was

statistically significant. Beck Depression Inventory scores

did not correlate significantly with scores from either scale.

Perceived Control

A separate analysis of variance (Depression X Tasks) was

conducted for each of the six scales which comprise the

Perceived Control Response Scale (PCRS). Only the statis-

tically significant results will be presented. The skill,

chance, and no-instructional-set groups recorded signifi-

cantly different scores on the Finances scale, F (2, 42) =

3.23, p <.05. A post hoc protected t-test revealed no sig-

nificant differences bewteen group means, however, so that

the nature of the differences in scores cannot be specified

further. The PCRS total score was significantly related to

Initial Expectancy, r (46) = .41, p < .01, indicating that

increased feeling of control was associated with higher ini-

tial expectancy of success.

Age and Sex

An analysis of variance (Depression X Tasks) for age

revealed that the skill, chance, and no-instructional-set

groups differed significantly in terms of age composition,

F (2, 42) = 4.25, p < .05. There was a significant interac-

tion between age and depression, F (2, 42) = 4.45, p < .05.

Post hoc protected t-tests indicate that each group differs

significantly from every other group (p < .05) with the

single exception that the depressed/skill and depressed/

no-instructional-set groups did not differ significantly

from one another. As can be seen from Table 5, the signif-

icant effect for interaction seems to be the result of the

ages of depressed subjects--depressed/skill and depressed/

no-instructional-set subjects were significantly younger

than all other subjects, while depressed/chance subjects

were significantly older. It is uncertain what effect

these differences had on the experimental results, however.

There were 14 males in the final sample of 48 subjects

who were scattered disproportionately throughout the total

sex on each of the dependent measures was not possible due

to the low numbers of males involved.

significantly different responses to the "explanation" ques-

tion; F (2, 42) = 3.82, p < .05. A post hoc protected t-test

revealed no significant differences between groups means,

however, so that the nature of the differences in response

cannot be specified further. Analyses of variance conducted

for the "average" and "difficulty" questions revealed no

significant effects. Initial expectancy was significantly

correlated with responses to the "average" question, r (46) =

.39, p < .01, indicating that greater initial expectancy of

success is related to increased feelings of performing "above

Discussion

The results fail to provide complete support for the

learned helplessness model of depression. The experimental

manipulations of skill, chance, and no-instructional-set

failed to produce any significant differences between groups.

Learned helplessness theory predicted that depressed subjects

would show significantly less expectancy change in the skill

condition when compared to nondepressed subjects, but that

Page 39: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

34

there would not be a significant difference in their responses

in the chance condition. For two measures, only the latter

prediction was supported. On the third measure (expectancy

change following success) there were significant differences

in the responses of depressed and nondepressed subjects, but

in the direction contrary to prediction. There were no dif-

ferences between experimental conditions. There are several

possible reasons for the failure to demonstrate a significant

difference in responses between depressed and nondepressed

subjects in the skill condition.

1. Learned helplessness is not a valid model of clini-

cal depression, and expectancy of control is not a relevant

factor in the deveopment of depression. This contention

might seem to be supported by the general lack of a relation-

ship between BDI scores and scores on the Perceived Control

Response Scale. Previous research, however, has demonstrated

that mild depression does seem to follow the learned helpless-

ness model (Maier & Seligman, 1976). Further, Miller (1975)

has presented evidence which suggests that the behavioral

deficits of depression seem to be associated not with specific

subtypes of depression (e.g., manic depressive illness), but

rather are common to all forms of depression and vary in

intensity with intensity of depression. This suggests that

a unitary phenomenon may be operating across all or most sub-

types and intensities of depression. At this point, it seems

Page 40: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

35

prudent to examine other possible explanations for the lack

of significant results in the skill condition.

2. The experimental manipulations of skill and chance

were not salient enough. Once the experiment was underway,

some subjects reported during debriefing that they had not

remembered the original skill/chance instructions during

the word-association test. It appears that the attribution

instructions which followed ("Previous research has shown

that success or failure on a test like this is usually

explained by four factors--ability, effort, task difficulty,

or luck . . .") served to counteract the skill/chance instruc-

tions for many subjects, rather than provide an integrative

framework as intended. This hypothesis is supported by the

observation that the expectancy-change scores of the skill

and chance groups did not differ significantly from those

of the no-instructional-set group, which received only the

attributional instructions. Other subjects displayed some

cognitive dissonance with respect to the chance instructions.

For example, one subject in the chance condition volunteered

that she felt she had a "50/50 chance" of success on one

particular trial, yet while making attributional ratings,

she rated luck at 0,. commenting that "luck has nothing to do

with it." Apparently, a number of subjects saw "luck" and

"chance" as being two separate entities. The words "chance"

and "skill" were specifically chosen for the word-association

task to aid in differentiation from the factors of ability

Page 41: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

36

and luck, although it was felt the concepts expressed by both

sets of words were equivalent.

3. Depressed subjects perceived the word-association

task as being unimportant and therefore displayed no helpless

effects. Previous research has suggested that helpless

symptoms do not occur in subjects who are exposed to uncon-

trollable outcomes in situations which they deem to be

unimportant (Roth & Kubal, 1975). Although reinforcement

was actually uncontrollable in the present study, none of

the subjects seemed aware of this, and the task therefore

should not have induced helplessness. Other theorists

(Klein et al., 1976; Wortman & Brehm, 1975) have discussed

the relationship between task importance and helplessness

with respect to situations which induce helplessness but

not to situations in which helplessness generalizes from

one task to another, as would be the case here. Nonetheless,

it seems likely that helpless subjects would fail to act

helpless in situations which they see as being unimportant.

Unfortunately, no data related to the perceived importance

of the word-association task were collected so that this

hypothesis could not be supported or rejected.

The increased change in expectancy following success for

depressed subjects is difficult to explain. Learned helpless-

ness theory suggests that depressed subjects should show

small changes in expectancy in all conditions. Miller and

Seligman (1976), however, reported a similar although

37

nonsignificant result. The authors suggested that the demand

characteristics of the test task caused subjects to perceive

reinforcement as being response-dependent, in that random

responding could not be expected to lead to success. Simi-

larly, it is likely that subjects in the present study

reached the same conclusion about the word-association task.

It remains unclear as to the reason that depressed subjects

would magnify their successes rather than minimize them, as

one would intuitively expect. This phenomenon needs to be

investigated in other research studies.

The experimental results did provide partial support

for the predictions of attribution theory. Nondepressed

subjects, as predicted, rated a factor other than effort as

being the least influential factor in determining success

and failure. Depressed subjects rated all four factors

approximately equal in influence, so that there was no one

least-influential factor. Nondepressed subjects also tended

to rate the factors approximately equal in influence, with

the exception of luck which they rated as being less influ-

ential. The results are somewhat difficult to interpret.

Both depressed and nondepressed subjects may have felt that

success or failure on this test was essentially out of their

control. This could explain the lack of a significant dif-

ference between groups in the skill condition. The fact that

effort, the only factor which allows individual control, was

rated equivalently with all other factors (excluding luck

Page 43: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

38

for the nondepressed subjects) adds support to this idea.

On the other hand, subjects may have found the rating process

too complex and failed to make meaningful discriminations

between factors. Many subjects did display considerable

difficulty in grasping the relationship between the attribu-

tional concepts and the word-association task. This does

not explain the significantly lower rating the nondepressed

subjects made for luck, however. The relationship between

ratings may be task-specific, so that the subjects actually

perceived ability, effort, and task difficulty as being

equivalent in determining success and failure for this task.

Finally, subjects may have felt that another unspecified

factor was more important than the four attributional factors

in determining success and failure. The results of the

"explanation" question suggest that most subjects felt the

attributional factors explained only about one-half of their

performance, During the debriefing, subjects were asked to

specify other factors which they felt to be relevant. Many

subjects reported that education, experience, or background

were important, but there were no clear trends.

The IPAT Anxiety Scale was administered to the subjects

to determine if differences in anxiety level were related to

differences in some of the other dependent measures. Miller

et al, (1975) demonstrated that the deficits of learned

helplessness were specific to depression and not related to

anxiety, In the present study, anxiety was not significantly

Page 44: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

39

related to total expectancy change, but neither was depres-

sion. Anxiety did correlate significantly with depression

and was negatively related to initial expectancy. Similarly,

the Gambrill-Richey Assertion Inventory was administered to

determine the relationship between assertiveness and depres-

sion. Intuitively, subjects who tend to be nonassertive

should also tend to be depressed and/or anxious. Both the

Degree of Discomfort and Probability of Responding scales

proved to be nonsignificantly correlated with either depres-

sion or anxiety. Assuming this inventory is a valid measure,

assertiveness or nonassertiveness is not specific to depres-

sion or anxiety.

Seligman (1975) has suggested that perceived lack of

control over reinforcers is an important variable in the

development of helplessness. Scores on the Perceived Control

Response Scale proved to be poorly related to depression,

however. It could be that the situations sampled were not

seen as being relevant or important by the subjects. Alter-

natively, the concept of perceived control may have been

too vague or complex so that subjects had difficulty making

meaningful discriminations and therefore responded similarly

on each scale. The significant main effect for tasks on the

Finance scale merely indicates that the samples were not

equivalent, Similarly, the age and sex data obviously show

variation among groups due to differences in sampling, but

the effects of such differences are difficult to determine.

Page 45: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

40

Analysis of the follow-up questions revealed only one

significant result--a main effect for tasks on the explana-

tion question. The no-instructional-set group displayed a

tendency to report that the four attributional factors

explained less of their performance, although the difference

was not statistically significant (p < .05). Two results

were marginally significant (p < .10). Depressed subjects

tended to feel that they performed more poorly than did

nondepressed subjects, and chance subjects tended to report

that the test was more difficult than did skill or no-

instructional-set groups.

Summary

The experimental results only partially confirmed

learned helplessness theory predictions, possibly because

of methodological problems. Nondepressed subjects in the

skill condition failed to demonstrate increased expectancy

changes as compared to nondepressed subjects in the chance

condition. Several possible explanations for the results

were given, but the most plausible one appears to be that

the attributional instructions counteracted the effects of

the skill/chance instructions for many subjects. Experi-

menters seeking to adapt or replicate this design may wish

to make the experimental manipulations more salient to the

subjects or prepare experimental designs which will test for

the influence of such possible mediating variables as type

of task, length of task, and perceived importance of the task.

Page 46: LEARNED HELPLESSNESS, ATTRIBUTION, CLINICAL …/67531/metadc... · Learned helplessness, as an empirical phenomenon, has been demonstrated to occur in a variety of species (Seligman,

41

The predictions of attribution theory were only parti-

ally supported. Contrary to prediction, depressed subjects

failed to rate effort as being less influential than any

other factor, while nondepressed subjects rated effort as

being clearly more influential than luck, as predicted.

Further interpretation of the results is difficult because

both depressed and nondepressed subjects tended to rate most

factors equivalently. Future researchers may benefit by

using a ranking procedure or paired-comparisons technique

(see Dweck, 1975) to determine if differences exist to which

the current scales were not sensitive. The use of two rat-

ing scales--one for success and one for failure--did not

seem to facilitate the subjects' understanding of the attri-

butional concepts enough to justify the associated problems

in computation and analysis. An analysis of the experimental

results does not readily yield tangible implications for

therapy, suggesting that discussion of this topic would be

premature.
