Lifespan Development: Cognitive, Moral, and Identity Theories

Piaget's Cognitive Development Theory

  • Constructivist Approach: Children actively construct logico-mathematical understanding through physical interaction.

  • Intelligence: Successful cognitive adaptation to the environment.

  • Genetic Epistemology: Theory focuses on origins of understanding reality, particularly logical/mathematical structures.

  • Schemes (Schemas): Basic physical and cognitive structures (filters) for interpreting the world.

    • Initially motor-based, then become more cognitive.

  • Equilibration: Cognitive system seeks balance.

    • Disequilibrium: Current schemes don't match new information.

    • Equilibrium: Schemes match new information.

  • Adaptation Processes:

    • Assimilation: Making new information fit existing schemes (maintains schemes).

    • Accommodation: Making existing schemes fit new information (modifies schemes).

  • Stages of Cognitive Development:

    • Characteristics: Universal, invariant, irreversible, qualitative shifts.

    • Sensorimotor (0-2 years): Coordinating movement with sensory information.

      • Substages: reflexive schemes (0−10-1 month), primary circular reactions (1−41-4 months), secondary circular reactions (4−84-8 months), coordination of secondary circular reactions (8−128-12 months), tertiary circular reactions (12−1812-18 months), mental representations (1212 months-$2years).</p></li></ul></li><li><p><strong>Preoperational(years).</p></li></ul></li><li><p><strong>Preoperational (2-7years)</strong>:Mentalrepresentation,basiclogic,butlimitations:</p><ul><li><p><strong>Egocentrism</strong>:Difficultyunderstandingotherviewpoints.</p></li><li><p><strong>Centration</strong>:Focusingononlyonesalientaspect.</p></li><li><p>Failureto<strong>conserve</strong>:Notunderstandingpropertiesremainconstantdespiteappearancechanges.</p></li><li><p>Failurein<strong>perspective−taking</strong>.</p></li></ul></li><li><p><strong>ConcreteOperational(years)</strong>: Mental representation, basic logic, but limitations:</p><ul><li><p><strong>Egocentrism</strong>: Difficulty understanding other viewpoints.</p></li><li><p><strong>Centration</strong>: Focusing on only one salient aspect.</p></li><li><p>Failure to <strong>conserve</strong>: Not understanding properties remain constant despite appearance changes.</p></li><li><p>Failure in <strong>perspective-taking</strong>.</p></li></ul></li><li><p><strong>Concrete Operational (7-11years)</strong>:Overcomepreoperationallimitations;canconserve,decentrate,showreversiblethinking,classification,seriation,transitiveinferences.Limitedtoconcreteexperiences.</p></li><li><p><strong>FormalOperational(years)</strong>: Overcome preoperational limitations; can conserve, decentrate, show reversible thinking, classification, seriation, transitive inferences.

      • Factors Fostering Identity Achievement: Cognitive development, parental relationships, experiences outside home, cultural influences.
