Piaget’s Theory of Cognitive Development How it is the Structure and Function of Cognition Unfolds
How it is the Structure and Function of Cognition Unfolds • 1. Born in Switzerland. • 2. Worked with some “heavyweights” in France. • 3. Concerned with manipulative behavior of children-- how they come to know things. • 4. Developed an inductively built theory. • 5. His influence here in the U.S.
Basic Elements to A Theory A Theory is Made Up of Component Parts Assumptions Concepts Structure The “givens of a theory accepted w/o proof The elements on which the theory is built What the theory “looks” like when it is graphically illustrated
Assumptions of Piaget’s Theory • Humans are biological organisms made up of reflexes and drives. • Humans are not passive in their development. • Humans a combination of genetic makeup and environmental influences. • Mental growth consists of two processes: (a) development and (b) learning
Structure and Function of Cognition: Explanatory Concepts • Schemata-- refers to cognitive structures. • Organization-- refers to the way schemata are organized and set up. • Adaptation-- refers to the invariant process of change in schemata. • Equilibrium-- refers to the cognitive balance that humans strive for through out development

Piaget’s theory is a Stage Theoryof Cognitive Development Formal Operational Period Concrete Operational Period Pre-operational Period Sensorimotor Period
Plane of Thought Formal Operational Period Concrete Operational Period Pre-operational Period Sensorimotor Period Plane of Action
Sensorimotor Period • Substage 1: Reflexive or S-R Behavior • Substage 2: Primary Circular Reactions • Substage 3: Secondary Circular Reactions • Substage 4: Coordination of Secondary Schemata • Substage 5: Tertiary Circular Reactions • Substage 6: New means through Mental Combinations
Preoperational Period • Divided into 2 subperiods: The Preconceptual (2-4) and The Intuitive (4-7) • Major Characteristic: Symbolic Function evidenced by language, imaginative play, increase in deferred imitation. • Acceleration of language is regarded as an outcome of the development of symbolization, rather than the inverse.
Preoperational Thought is Characterized by the Following • Egocentrism • Centration • State Fixation • Unstable Equilibrium • Irreversibility • Transduscive Reasoning
Piaget’s Demonstration of Preoperational Thinking Errors: Conservation Tasks • Conservation of Volume • Conservation of Mass • Conservation of Number • Conservation of Length
