Biological MotivesThe Biology of MotivationDrive Reduction Theory
The Biology of MotivationHomeostasis
the tendency of all organisms to correct imbalances and deviations from their normal state
HungerLateral Hypothalamus (LH)
when stimulated animals begin eating
if removed animals stop eating and starve to death
“go” signalVentromedial Hypothalamus
(VMH)when stimulated animals slow or stop eating
if removed animals eat everything
“stop” signalAffected by temperatures
LH by coldVMH by warm
Glucostatic TheoryHypothalamus monitors glucose in the blood
Pancreasinsulin- calories to energyglucogon- converts stored energy back to useful energy
Set point- day to day weight
ObesityStanley Schachter
Obese people respond to external cues
“Taste Test”crackers and almonds
Overweight people respond to external cues
Normal weight people respond to internal cues
Anxiety and depression are not a cause of overeatingoccur just as frequently
Drive Reduction Theory Clark Hull Physiological needs drive an
organism to act in either random or habitual ways until its needs are satisfied
All human motives are extensions of basic biological needs
Harry HarlowSome experiences are inherently
pleasurable but don’t reduce biological drives
Drive for stimulation as plausible as a drive to reduce stimulation
Social MotivesMeasuring the Need for
AchievementMaslow’s Hierarchy of Needs
Social MotivesHenry Murray
Theory of personality includes 16 basic needs
Mostly social motives rather than biological needs
Measuring the Need for AchievementDavid McClelland
Interested in finding a quantitative way of measuring social motives
Thematic Appercetion Test (TAT)series of picturesstories made up for picturescoded for themes and scored according to relevance to various types of needs
coders agree 90% of the time1947 test group
more entrepreneurs scored high than nonentrepreneurs
Fear of SuccessMarina HornerTested 89 men and 90 women“After first term finals,
John/Anne finds himself at the top of his medical school class”
Men- 90% wrote success storiesWomen- 65% predicted doom for
Anne Identified a motive to avoid
successFemale success was odd and
unfeminine
Could mean failure as a woman if successful in a traditionally male field
Later researchhard to define successseen in males and females45% of men and 49% of women
Other TheoriesExpectancy-value Theory
likelihood of successwhat the goal is worth to you
Competency Theoryto prove and improve our competency we choose moderately difficult tasks where both successes and failures may be instructive
ring-toss game
Intrinsic and Extrinsic Motivation
Maslow’s Hierarchy of NeedsFundamental Needs
biological drives, safety, securityPsychological Needs
belong and receive love, acquire self-esteem through competence and achievement
Maslow’s Hierarchy of NeedsSelf-actualization Needs
pursuit of knowledge and beauty, realization of one’s unique potential
Research does not support that one need must be satisfied before another can be
EmotionExpressing Emotions: Innate and
Learned BehaviorPhysiological TheoriesCognitive Theories
Emotion Difference in biological drives and
emotions both involve changes in physiological
state source of behavior or feelings involved
with behavior May drive us to act May serve as incentive for action
Expressing Emotions: Innate and Learned BehaviorEkman and Friesen
photo study to recognize facial expressions
Facial expressions are innateBlind/Deaf children
laugh, pout, frown, clench fists
Carroll Izard coding system for assessing
emotional states in people 10 different states used to study expressions in infants
James Averill can’t separate thoughts and actions
from experience of emotions from social expectations or
consequencesDifferences among cultures
Physiological TheoriesWilliam James
we associate feelings with energy, tension, relaxation, and sensations in our stomach
James-Lange TheoryCannon-Bard Theory
James-Lange Theory Use emotion to describe our “gut”
reactions to the things that take place around us
Emotions are the perceptions of certain bodily changes
Izzard and feedback from facial muscles
Cannon-Bard TheoryEvidence against James-Lange
physiological changes occur when people are not experiencing emotions
injecting a drug does not change emotions though it changes physical properties
Cannon-Bard TheoryInternal state of body changes slowly, not like the “rush” of emotions we sometimes get
Cannon-Bard TheoryCannon called the thalamus the
seat of emotionTheory says certain experiences
activate the thalamus, and it sends signals simultaneously to the body and the brain
Cognitive TheoriesBodily changes and thinking work
together to produce emotionsFeelings depend on how you
interpret your symptoms
Cognitive TheoriesThe Schachter-Singer
ExperimentOpponent-Process TheoryLie Detection
The Schachter-Singer ExperimentStanley Schachter and Jerome
Singer “Testing the effects of vitamin C
on eyesight”Adrenalin injectionFour Groups
Informed Group- truth (hearts race and bodies tremble)
Misinformed Group- make numb Uninformed Group- not told anything Control Group- received neutral
injection without symptoms and told nothing
Taken to waiting roomAccomplice
wild and crazy with offensive questionnaire became
more and more angry
Results groups 1 and 4 watched with mild
amusement groups 2 and 3 joined in with the
accomplice Internal components of emotion
affect a person differently depending on perception of the social situation
Opponent-Process TheoryHomeostatic theory of emotional
reactionsRichard Solomon and John CorbitAny intense emotion, with
repeated exposure, will bring about an internal counterforce
Lie Detection
