differences • Uncover mechanisms of cognitive development © Allyn & Bacon/ Longman 2007 Basics of Piaget’s Theory General theory Considers all aspects of cognition Constructivist approach • Stages are invariant • Stages are universal © Allyn & Bacon/ Longman 2007 Schemes • Are psychological structures • Organized ways of making sense of experience • Change with age © Allyn & Bacon/ Longman 2007 Assimilation & Accommodation • Assimilation Using current schemes to interpret external world Accommodation Adjusting old schemes, creating new ones to better fit environment © Allyn & Bacon/ Longman 2007 Piaget’s Sensorimotor Stage • Birth to 2 years • Building schemes through sensory and motor exploration • Circular reactions © Allyn & Bacon/ Longman 2007 Sensorimotor Substages Reflexive Schemes Birth –1 month Newborn reflexes Primary Circular Reactions 1 – 4 months Simple motor habits centered around own body Secondary Circular Reactions 4 – 8 months Repeat interesting effects in soundings Coordination of Secondary Circular Reactions 8 – 12 months Intentional, goal-directed behavior; object permanence Tertiary Circular Reactions 12 – 18 months Explore properties of objects through novel actions Mental Representations 12 months – 2 years Internal depictions of objects or events; deferred imitation © Allyn & Bacon/ Longman 2007 Object Permanence • Understanding that objects continue to exist when out of sight • According to Piaget, develops in Substage 4 • Incomplete at first: A-not-B Error © Allyn & Bacon/ Longman 2007 Evaluation of the Sensorimotor Stage Timing of: How Piaget was • Object search, right • A-not-B, • Make-believe play • Timing of object permanence, deferred How Piaget imitation, categorization, problem-solving might have been by analogy wrong • All occur sooner than Piaget thought Some suggest infants are born with core knowledge in several domains of thought © Allyn & Bacon/ Longman 2007 Gains in Preoperational Mental Representation • Language Piaget believed it developed from sensorimotor experiences • Make-believe play • Dual representation © Allyn & Bacon/ Longman 2007 Benefits of Make-Believe Play • Practice representational schemes • Emotional integration • Social, language skills • Attention, memory, logical reasoning • Imagination, creativity © Allyn & Bacon/ Longman 2007 Dual Representation • Viewing a symbolic object as both an object and a symbol • Mastered around age 3 • Adult teaching can help Provide lots of maps, photos, drawings, make-believe playthings, etc. Point out similarities to real world © Allyn & Bacon/ Longman 2007 Limitations of Preoperational Thought • Cannot perform mental operations • Egocentrism and animistic thinking • Cannot conserve • Lack hierarchical classification © Allyn & Bacon/ Longman 2007 Egocentrism Failure to distinguish others’ views from one’s own © Allyn & Bacon/ Longman 2007 Animistic Thinking Belief that inanimate objects have lifelike qualities © Allyn & Bacon/ Longman 2007 Limits on Conservation • Centration Focus on one aspect and neglect others • Irreversibility Cannot mentally reverse a set of steps © Allyn & Bacon/ Longman 2007 Follow-Up Research on Preoperational Thought Egocentric Thought • Can adjust language to others and take others’ perspectives in simple situations • Animistic thinking comes from incomplete knowledge of objects • Can do simplified conservation Illogical Thought • Can reason by analogy • Use causal expressions Categorization • Everyday knowledge is categorized Appearance versus reality • Can solve appearance-reality tasks in nonverbal ways © Allyn & Bacon/ Longman 2007 Evaluation of the Preoperational Stage How Piaget was Preschoolers do develop beginnings of right logical thinking How Piaget might have been wrong Logical thinking develops more gradually than Piaget thought © Allyn & Bacon/ Longman 2007 Achievements of the Concrete Operational Stage • Conservation Decentration Reversibility • Classification • Seriation Transitive inference • Spatial Reasoning Directions Maps © Allyn & Bacon/ Longman 2007 Limitations of Concrete Operational Thought • Operations work best with objects that are concrete Problems with abstract ideas • Horizontal décalage Master concrete operational tasks gradually © Allyn & Bacon/ Longman 2007 Follow-up Research on Concrete Operational Thought • Culture and schooling affect performance on tasks Going to school gives experience on Piagetian tasks © Allyn & Bacon/ Longman 2007 Piaget’s Theory: Formal Operational Stage Hypothetico-deductive reasoning Deducing hypotheses from a general theory Pendulum problem • Propositional Thought Evaluating the logic of verbal propositions © Allyn & Bacon/ Longman 2007 Consequences of Abstract Thought • Self-Consciousness & Self-Focusing Imaginary audience Sensitivity to criticism • Idealism and Criticism • Problems with Decision Making Inexperience Overwhelming options © Allyn & Bacon/ Longman 2007 Follow-up Research on Formal Operational Thought • School-age children start developing abstract thinking skills Problems with propositional thinking Logical necessity Careful thinking about major premise • Formal operations may not be universal Training, context contribute Often fall back on easier thinking © Allyn & Bacon/ Longman 2007 Educational Principles Derived from Piaget’s Theory • Discovery learning • Sensitivity to children’s readiness to learn Developmentally appropriate practices • Acceptance of individual differences © Allyn & Bacon/ Longman 2007 Overall Evaluation of Piaget’s Theory Piaget’s change processes — assimilation, accommodation, and organization — can’t account for patterns of children’s changes observed today Cognitive development not always selfgenerating Cognition not as broadly stagelike as Piaget believed Piaget’s theory still inspires research © Allyn & Bacon/ Longman 2007 Core Knowledge Perspective • Evolutionary perspective: infants start life with innate, special-purpose knowledge systems Core domains of thought • Core domains prepare us to rapidly develop key aspects of cognition • Development is domain-specific Children as naïve theorists © Allyn & Bacon/ Longman 2007 Suggested Domains of Core Knowledge • • • • • Physical Numerical Linguistic Psychological Biological © Allyn & Bacon/ Longman 2007 Development of Infants’ Physical Knowledge One solid object cannot move through another 2 - 3 months Size comparisons - notice when objects are: • Too wide for openings 5-6 months • Too tall for containers 7-8 months Gravity, object support 6- 7 months © Allyn & Bacon/ Longman 2007 Theory of Children as Theorists Children: • Observe an event • Explain, or theorize about its cause Draw on innate concepts • Test theory against experience • Revise theory if needed © Allyn & Bacon/ Longman 2007 Evaluation of Core Knowledge Perspective Most serious consideration of beginnings of thinking Amount and nature of inborn knowledge hotly debated Suggests environment and experience work together, but does not clarify how Suggests cognitive development is independent; little attention to learning with others © Allyn & Bacon/ Longman 2007 Vygotsky’s Sociocultural Theory Cognition is based on: • Social interactions • Language © Allyn & Bacon/ Longman 2007 Children’s Private Speech • Piaget called this “egocentric speech” • Vygotsky viewed it as foundation for all higher cognitive processes • Helps guide behavior Used more when tasks are difficult, after errors, or when confused © Allyn & Bacon/ Longman 2007 Zone of Proximal Development Tasks child cannot do alone but can learn to do with help © Allyn & Bacon/ Longman 2007 Social Interactions that Promote Cognitive Development • Intersubjectivity • Scaffolding • Guided participation © Allyn & Bacon/ Longman 2007 Vygotsky and Make-Believe Play • Provides Zone of Proximal Development Imaginary substitutions help children

2007 Cooperative Learning Small groups of classmates work toward common goals Cultural variations in ability to learn cooperatively © Allyn & Bacon/ Longman 2007 Evaluation of Vygotsky’s Theory Helps explain cultural diversity in cognition Emphasizes importance of teaching Focus on language deemphasizes observation, other learning methods Says little about biological contributions to cognition
