  1. Cognitive DevelopmentNeo-Piagetian Research • Neo-Piagetian research • New research on sensorimotor stages • Object permanence • The A-not-B error • Immediate and deferred imitation • New research on preoperational thought • Egocentrism • Animism • Conservation • New research on concrete operations • The sequencing of conservation abilities • New research on formal operations • Does everyone achieve formal operations? • Does formal operations appear earlier than supposed? • Evaluation of Piaget’s theory • Piaget underestimated developing minds • Competence versus performance • Does development occur in stages? • The explanation of intellectual development • The importance of social and cultural influences

  2. New Research on Sensorimotor StagesObject Permanence • Rene Baillageon • Elizabeth Spelke • Baillargeon, Spelke, & Wasserman (1985) • Habituation Display • Test 1 • Test 2

  3. New Research on Sensorimotor StagesThe A-not-B Error • A trials: • A location B location • Toy hidden here in front of infant • Infant searches here • B trials: • A location B location • Toy hidden here in front of infant • Infant searches here

  4. New Research on Sensorimotor StagesThe A-not-B error • Bjork & Cummings (1974) • Spatial orientation versus memory deficit • A trials: • Infant searches here • B trials: • Infant searches here X X

  5. New Research on Sensorimotor StagesImmediate and Deferred Imitation Meltzoff & Moore (1994)

  6. New Research on Preoperational Thought • John Flavell • Egocentrism • John Flavell • Lemperers et al. • Animism • Dolgin & Behrend • Conservation • Dolgin & Behrend

  7. New Research on Concrete Operations • Problems with the sequencing of abilities • Horizontal decalage

  8. New Research on Formal Operations • Is there evidence for formal operations earlier than supposed? • Positive If … then … statements • Premise 1: If Jack washes the dishes, his father will be pleased. • Premise 2: If Jack’s father is pleased, Jack receives a toonie. • Premise 3: Jack washes the dishes. • Conclusion (?): Jack gets a toonie.

  9. New Research on Formal Operations • Is there evidence for formal operations earlier than supposed? • Negative If … then … statements • Premise 1: If there is a knife there is a fork. • Premise 2: There is not a knife • Conclusion (?): There is not a fork.

  10. Evaluation of Piaget’s Theory • Piaget’s contributions: • Humans are active in their own development • Young humans think differently than older humans • Impetus for researchers • Challenges to Piaget: • Piaget underestimated the abilities of young minds • Is this a serious criticism? • The competence versus performance issue • Does cognitive development occur in stages? • Stages as “holistic” structures • Horizontal decalage • Piaget’s explanation of intellectual development • Too little attention paid to social and cultural factors
