Coffee & Cream
Begin with two identical large cups, Cup 1 containing 8 oz. of cream, Cup 2 containing 8 oz. of coffee (or diet Coke)
Remove 2 oz. of cream from Cup 1 and place it in Cup 2. Mix thoroughly.
Remove 2 oz. of the coffee/cream mixture in Cup 2 and place it in Cup 1.
Question: Is there1. More coffee in Cup 1 than cream in Cup 2?2. More cream in Cup 2 than coffee in Cup 1?3. The same amount of cream in Cup 2 as coffee in Cup 1?4. None of the above.

Introduction to Piaget
3rd Most influential psychologist of the 20th century
Father of Cognitive Developmental Theory
Background facts
5
Major Thesis
Social development is a consequence of changes in cognitive development
Responsible in large part for Social Cognition (e.g., gender conceptions, humor)
6
The Nature of Piaget’s Theory
Strong stage theory. Stages are: Qualitative (rather than quantitative) Coherent (consistent) Fixed (just four, no more) Universal (applicable to all, though not all are
believed to achieve all the stages), and Invariant (we all go through them in the
same order; no skipping).!
o Based on structure of thought, rather than on content of thought
7
How does Growth Occur?
o 1. Through both nature and nurture; maturation + certain critical experiences
o 2. In general, through accommodation and assimilation
o 3. Though Cognitive Disequilibrium
o 4. Though Interactions with Peers—particularly when older
8
Stages (1)
Sensorimotor (0‑2). From reflex to reflective! Develops distinction between self & non-self Object… Delayed…
Preoperational (2‑7). At this stage children have not yet gained the operations that allow them to think logically. Perception is characterized by centration & thinking by egocentrism Increasing use of symbols (e.g., pretend play), but Perceptual centration & Egocentrism, which together Preclude conservation
9
Egocentrism
10
Stages (2)
Concrete operation (7‑12) use operations (e.g., transitivity), but fixed on
real Can conserve
Formal operations (12‑?); can deal with Abstractions logical reasoning hypotheticals
11
Some Conservation Tasks
12
Still More Conservation Tasks
13
Some important implications of Piaget: Learning?
Learning is a product of one's cognitive development. The child's existing cognitive
structures determine how he/she interprets social experiences and, hence, what is likely to be learned from interactions with others
14
What about Personality?
Dependent upon cognitive development; e.g., can't have notion of gender, until conservation.
The Brain: Cognition; you get it, right?
15
A Practical Application: Teaching Traditional Gender Behavior
Match the instructional approach to the developmental level of the child
Has the child developed the notion of gender constancy?
Help the child form concept that she is a girl.
16
How Stages are “Discovered” Someone has a notion that a stage-like progression
typifies some developmental phenomena (e.g., how babies occur)
Select children of various ages (cross-sectional study), and inquire about the phenomena
Follow up with longitudinal study to insure that the changes typify each individual’s developmental trajectory Adjust design so that time period covers critical
growth period Insure that sufficient assessments are conducted to
distinguish continuous from stage-like development
17
Evaluation: Strengths
Importance of cognition -- even for social content!
o Process of thinking rather than content of thought
o Wonderful descriptive frameworko Wonderful descriptive framework
o Always take into account developmental level
18
Evaluation: Weaknesses
Strong on developmental function; weak on IDs Specific ages often erroneousa. When we think an
event or a process occurs is in part a function of how we conduct the assessment!
Characteristics of stages gone awrya: Coherence of stages: conservation problems not
conservation problem....(Gertrude Stein) Backsliding, Training individuals at an age earlier than when the operation
is to have developed Universality (e.g., in moral development we have substantial
cultural differences) Description not explanation

What about Black & White Marbles? Urn 1 contains 100 white marbles; Urn 2 100 black
marbles. Take 20 of the white marbles from Urn 1 and place them
in Urn 2. Mix the marbles well. Take 20 of the mixture of marbles in Urn 2 and place them
in Urn 1 The Question:
1. Is there more black marbles in Urn 1 than white marbles in Urn 2?
2. Is there more white marbles in Urn 2 than black marbles in Urn 1?
3. Is there is same number of white marbles in Urn 2 as black marbles in Urn !?
4. None of the above.
