Interested in biology and philosophy as a child. At the University of Neuchâtel he became intrigued by psychology. At the University of Neuchâtel he became intrigued by psychology. Working at the Binet Institute in Paris, Piaget became interested in the wrong answers children would give, and from that, developed his theory of cognitive development. He married Valentine Châtenay in 1923. The intellectual development of their three children Jacqueline, Lucienne, and Laurent became the focus of his research.

4. Piaget’s Theory of Cognitive Development Sensori-Motor: The infant uses senses and motor abilities to understand the world, beginning with reflexes and ending with complex combinations of sensori-motor skills. (Birth – 2 years) Sensori-Motor: The infant uses senses and motor abilities to understand the world, beginning with reflexes and ending with complex combinations of sensori-motor skills. (Birth – 2 years) Pre-Operational: The child begins to use symbols and is still egocentric in thinking. (Ages 2-7) Pre-Operational: The child begins to use symbols and is still egocentric in thinking. (Ages 2-7) Concrete Operational: The child can use logic and symbols, but only when applied to concrete situations. (Ages 7-11) Concrete Operational: The child can use logic and symbols, but only when applied to concrete situations. (Ages 7-11) Formal Operational: The child applies his new-found logical abilities to non-concrete/abstract events. This involves using logical operations, and using them in the abstract, rather than the concrete. We often call this hypothetical thinking. (Ages 12+) Formal Operational: The child applies his new-found logical abilities to non-concrete/abstract events. This involves using logical operations, and using them in the abstract, rather than the concrete. We often call this hypothetical thinking. (Ages 12+)

Sensori-Motor Period Stage 1: First Reflexes Stage 1: First Reflexes Birth – 1 month Stage 2: Primary Circular Reactions Stage 2: Primary Circular Reactions 1 – 4 months Stage 3: Secondary Circular Reactions Stage 3: Secondary Circular Reactions 4 – 8 months Stage 4: Coordination of Secondary Circular Reactions Stage 4: Coordination of Secondary Circular Reactions 8 – 12 months Stage 5: Tertiary Circular Reactions Stage 5: Tertiary Circular Reactions 12 – 18 months Stage 6: The Beginnings of Thought Stage 6: The Beginnings of Thought 18 – 24 months

6. Characteristics of Stage Four Coordination of Secondary Schemata Coordination of Secondary Schemata An example of a secondary scheme An example of a secondary scheme An example of the consequent coordination of those schemes

7. Object Permanence Stage Three: Inability to find a hidden object. Stage Three: Inability to find a hidden object. Stage Four: Ability to find an object hidden in one position. Stage Four: Ability to find an object hidden in one position. Stage Five: Ability to follow an object through a series of displacements. Stage Five: Ability to follow an object through a series of displacements. Stage Six: Ability to follow “invisible displacements.” Stage Six: Ability to follow “invisible displacements.”

8. Driving Questions If Piaget underestimated the rate of development in children during the pre-operational and concrete operational stages, did he also underestimate development in sensori-motor children? If Piaget underestimated the rate of development in children during the pre-operational and concrete operational stages, did he also underestimate development in sensori-motor children? Will a nine-month-old child demonstrate actions that correspond to the “appropriate” stage (stage four)? Will a nine-month-old child demonstrate actions that correspond to the “appropriate” stage (stage four)? Will the child have developed all of the traits Piaget expects in coordination of secondary circular reactions and object permanence? Will the child have developed all of the traits Piaget expects in coordination of secondary circular reactions and object permanence?

9. Hypothesis Since Piaget was basically brilliant* and studied the sensori-motor stage of cognitive development very thoroughly, the results should correspond to Piaget’s expectations regarding sensori-motor skills and object permanence. *Albert Einstein said once that Piaget’s conclusion that children were not less intelligent than adults, but rather simply thought differently was a discovery “so simple only a genius could have thought of it.”

10. Research Study A nine-month-old child, A nine-month-old child, Johnny, was used in this study. The goal was to recreate The goal was to recreate Piaget’s own experiments from The Origins of Intelligence in the Child, to see if they corresponded with Johnny’s reactions.

11. Piaget’s Tasks Relinquishing an Object: Offer an exciting toy to infant when he is playing with another less exciting toy. Relinquishing an Object: Offer an exciting toy to infant when he is playing with another less exciting toy. Means-End Coordination: Play a toy behind a screen (hand). Means-End Coordination: Play a toy behind a screen (hand). Means-End Coordination: Present infant with an object; hold onto object’s other end. Means-End Coordination: Present infant with an object; hold onto object’s other end. Causality/Use of Intermediaries: Clap hands; clap hands within arm’s reach of the infant. Causality/Use of Intermediaries: Clap hands; clap hands within arm’s reach of the infant. Object Permanence Test: Take a popular toy, let the infant see it hidden at point A. Note reaction. Hide toy again at point A. Note reaction. Hide toy at point B, making sure the infant saw it placed in a different spot.

17. Results Basically, Johnny reacted to these tasks as Piaget suggested that he would. Basically, Johnny reacted to these tasks as Piaget suggested that he would. However, in object permanence, Johnny’s actions placed him in Stage Five (typically associated with 12 - 18 month-old infants). However, in object permanence, Johnny’s actions placed him in Stage Five (typically associated with 12 - 18 month-old infants). This exception is leveled out, considering that Johnny did not clearly displace his toys in “relinquishing an object,” preventing his decisive placement in either Stage Three or Four. This exception is leveled out, considering that Johnny did not clearly displace his toys in “relinquishing an object,” preventing his decisive placement in either Stage Three or Four. Generally, Johnny placed within Stage Four, attesting to Piaget’s characteristic thoroughness regarding the sensori-motor period of child development.

18. Limitations Only one child was studied Only one child was studied Could have better addressed Piaget’s underestimation of children if more children had been studied Could have better addressed Piaget’s underestimation of children if more children had been studied Lack of time Lack of time Only three meetings with Johnny—would have been useful to explore the development over time Only three meetings with Johnny—would have been useful to explore the development over time
