1. JBCurts/2005 Stages of Cognitive Development Dr. Jaime Curts The University of Texas Pan American Fall 2005

2. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Sensorimotor stage (Infancy) In this period (which has 6 substages), intelligence is demonstrated through motor activity without the use of symbols.

3. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Sensorimotor stage (Infancy) Knowledge of the world is limited because it is based on physical interactions/ experiences.

4. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Sensorimotor stage (Infancy) Children acquire object permanence at about 7 months of age.

5. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Sensorimotor stage (Infancy) Physical development (mobility) allows the child to begin developing new intellectual abilities.

6. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Sensorimotor stage (Infancy) Some symbolic (language) abilities are developed at the end of this stage.

7. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Pre-operational stage (Toddler and Early Childhood) Intelligence demonstrated through the use of symbols, language use matures, and memory and imagination are developed.

8. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Pre-operational stage (Toddler and Early Childhood) Thinking is done in a nonlogical, nonreversable manner.

9. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Pre-operational stage (Toddler and Early Childhood) Egocentric thinking predominates.

10. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Concrete operational stage (Elementary and early adolescence) This stage is characterized by 7 types of conservation: number, length, liquid, mass, weight, area, and volume.

11. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Concrete operational stage (Elementary and early adolescence) Intelligence is demonstrated through logical and systematic manipulation of symbols related to concrete objects.

12. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Concrete operational stage (Elementary and early adolescence) Operational thinking develops (mental actions that are reversible).

13. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Concrete operational stage (Elementary and early adolescence) Egocentric thought diminishes.

14. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Formal operational stage (Adolescence and adulthood) Intelligence is demonstrated through the logical manipulation of symbols related to abstract concepts.

15. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Formal operational stage (Adolescence and adulthood) Early in this period there is a return to egocentric thought.

16. JBCurts/2005 Stages of Cognitive Development Piaget identified four stages in cognitive development: Formal operational stage (Adolescence and adulthood) Many adults never attain this stage.

17. JBCurts/2005 Research Studies Piaget's research methods were based primarily on case studies [they were descriptive]. While some of his ideas have been supported through more correlational and experimental methodologies, others have not.

18. JBCurts/2005 Research Studies For example, Piaget believed that biological development drives the movement from one cognitive stage to the next. Data from cross-sectional studies of children in a variety of western cultures seem to support this assertion for the stages of sensorimotor, preoperational, and concrete operations.

20. Research Studies However, data from similar cross-sectional studies of adolescents do not support the assertion that all individuals will automatically move to the next cognitive stage as they biologically mature. For formal operations, it appears that maturation establishes the basis, but a special environment is required for most adolescents and adults to attain this stage.

22. Research Studies Although research does not support all of Piaget’s descriptive theory, it is still influential for parent’s and educators.
