I. Developmental Psychology
A. The Study of Development
*The study of how people grow and change throughout the life span
*Interest in early childhood experiences affect people as adolescents and adults
*Helps understand developmental problems, what causes them, and how to treat them.

I. Developmental Psychology
A. The Study of Development
1. Two methods to study change:
a. longitudinal method –
1.select a group of participants and then observe that same group for a period of time…years or even
decades
2. Advantage observe, compare, contrast over times as they mature
3. Drawbacks – some withdraw, studying may affect or alter
behaviors
04/22/23 5
• Stanford University psychology researcher Michael Mischel demonstrated how important self-discipline (the ability to delay immediate gratifiction in exchange for long term goal achievement) is to lifelong success? In a longitudinal study which began in the 1960s, he offered hungry 4-year-olds a marshmallow, but told them that if they could wait for the experimenter to return after running an errand, they could have two marshmallows.
Those who could wait the fifteen or twenty minutes for the experimenter to return would be demonstrating the ability to delay gratification and control impulse. About one-third of of the children grabbed the single marshmallow right away while some waited a little longer, and about one-third were able to wait 15 or 20 minutes for the researcher to return.
Years later when the children graduated from high school, the differences between the two groups were dramatic: the resisters were more positive, self-motivating, persistent in the face of difficulties, and able to delay gratification in pursuit of their goals. They had the habits of successful people which resulted in more successful marriages, higher incomes, greater career satisfaction, better health, and more fulfilling lives than most of the population.
This is Dayton. He is a 3 1/2 yr old with Prader willi syndrome (In short most cases cannot control their urges for food) He is a funny, sassy little boy who pushes things to the limits! He went farther than we all thought he could!!

b. Cross-sectional method
1. select a sample that includes people of different ages.
2. compare the participants in the different age groups
3. advantages: less time consuming, less expensive
4. drawbacks: grown up with different educational methods, medical treatments, cultural influence.

B. Heredity and Environment
1. Debate between which is more influential.
2.Heredity
a. how do your genes effect your development? Use kinship studies.b. maturation – automatic and
sequential process of development that results from genetic signals. (sequences that happen automatically, roll over, sit up, crawl, etc.)
c. normal time range
d. Critical period – is a stage or a point in development during which a person is
best suited to learn a particular skill or behavior pattern. i.e. Language Genie

Type1: Predict an outcome for Genie. Give me three reasons why you think it will happen.
Type 1
• Compare/Contrast Nativist (biology v. Nurturist (environment theories. What is similar and what is different about each of them. You may use notes, your book or other tools. You must have a minimum of three comparisons and three contrasts.
04/22/23 12
e. Language development
1. cries
2. 2-3 months coos (vowels)
3. 6 months – babble (consonants)
4. 1 year overextend words – using words to include objects that do not fit the word’s meanings “doggie” any furry animal.
5. 2 years – telegraphic – 2-3 word sentences linking words
6. over generalize – extend the rules for past tense and plural to irregular form.
“My foots hurt.’
7. LAD (language acquisition device)

e. tabula rasa – blank slate – infant’s mind
2. Heredity
a. Watson and other behaviorist present environmental explanations. Factors such as nutrition, family background, culture, learning experiences in the home, community and school.
3. Today – agree both play a role.
04/22/23 14
C. Stages Versus Continuity
* Debate – do we change in steps or is it just continuous?
1. A stage – like one step in a stair case, a period or a level of development process…have to walk in the order to get there
a. Maturational theorist such as Gesell believe that most development occurs
in stages
b. Jean Piaget – one of most famous – he studied how children think – different
children reach different stages at different times

* best known researcher in childhood development
16
http://www.youtube.com/watch?v=Jw33CBsEmR4&feature=related
Piaget’s Stages of Cognitive Development
Stage Age Characteristics
Sensorimotor Stage 0-2 •Learning to coordinate sensation and perception with motor activity•Development of object permanence
Preoperational Stage 2-7 •One-dimensional thinking•Displays of egocentrism, artificialism, and animism
Concrete-Operational Stage
7-12 •Signs of adult thinking about specific objects but not abstract ideas•Reduced egocentrism
Formal-Operational Stage
12+ •Capable of abstract thinking•Able to deal with hypothetical situations, strategize, and plan ahead to solve problems
04/22/23 17

color.3. To watch my favorite

04/22/23 20
c. Erick Erickson – focused on the role of social relationships – believed people
pass through eight stages in healthy development of their personalities
d. J.H. Flavell – argues that cognitive development is a gradual process – it
is continuous

Get out a piece of paper. If you have had Mr. Schmidt over the past years write him a note and tell him something you will miss about him….be nice! =)
