Goals:
Describe Piaget's stages of cognitive development.
Discuss the assumptions and concepts underlying Piagetian theory.
Discuss the strengths and limitations of Piagetian theory of development.
Jean Piaget (1896–1980):
Pioneer in cognitive development theory.
Suggested infants and children think differently than adults, emphasizing qualitative differences.
Development significantly influenced by children’s actions in the world.
Social Context:
Acknowledged importance, yet viewed children as isolated learners constructing personal understanding.
Constructivist Approach:
Described children as ‘little scientists’ exploring their environment.
Overview of Stages:
Fundamental phases outlining cognitive development according to Piaget.
Key Features:
Reflexive movements evolve into deliberate actions.
Develops means-end behavior.
Gradual separation of self from the environment.
Achievement of object permanence.
Deferred imitation marks the conclusion of this stage.
Key Features:
Development of semiotic functions—using symbols for communication.
Enables thought about past and future and facilitates language use.
Characterized by egocentrism; difficulty in perspective-taking.
Struggles with logic in problem-solving (e.g., conservation tasks).
Key Features:
Ability to solve conservation tasks correctly marks entry into this stage.
Horizontal decalage: exhibits different rates of development within stages.
Logical thinking emerges but requires physical representation of problems.
Key Features:
Capacity for logical and abstract thinking.
Hypothetical reasoning is developed.
In-depth thinking about society and self-concept.
Internal cognitive structures become highly organized.
Introduction to the major concepts foundational to Piaget's theory of cognitive development.
Definition of Schemes:
Basic coordinated patterns of action or reasoning.
More complex schemes develop as children grow older, incorporating mental processes.
Children utilize schemes for interacting with their environments; earlier schemes facilitate the development of more sophisticated ones.
Assimilation:
Integrating new experiences into existing knowledge frameworks.
Accommodation:
Adjustments in behavior and cognition when existing schemes do not encompass new experiences.
Equilibration:
Self-regulatory process promoting increasingly organized and complex intellectual schemes through assimilation and accommodation.
Maturation:
Genetic programs unfold over time affecting development.
Children can actively engage with their environment, impacting their growth.
Developmental goals involve achieving stability between physically responding to and cognitively understanding interactions.
Cultural Influence:
Similar cognitive development patterns across cultures.
Cultural and educational experiences can alter the pace and extent of cognitive development.
Active Knowledge Construction:
Learning involves continuous restructuring of intellectual frameworks through activities and experiences.
Children are active learners, shaping their understanding of the world.
Developmental Trajectory:
Initially emphasized distinct stages, but later acknowledged ongoing changes in cognitive abilities, illustrating a 'spiral' of development across different rates.
Sensitive Learning Periods:
Stages of development reflect optimal times for learning.
Piaget viewed development as a lifelong process rather than strictly limit times.
Overview of the strengths and limitations inherent to Piaget's contributions to developmental psychology.
Recognition of Cognition's Role:
Highlights the significance of cognitive processes in development.
Reveals unexpected insights into children's thinking, such as object permanence and conservation.
Broad Scope:
Encompasses various behaviors and is applicable to everyday life.
Ecological Validity:
Focuses on how children adapt within their natural environments.
Cultural and Contextual Bias:
Primarily reflects Westernized perspectives, thus limited in cultural application.
Neglect of Individual Differences:
Fails to account for variations among individual children.
Limited Lifespan Focus:
Concentrates mainly on childhood, overlooking later stages of development.
Variable Task Outcomes:
Children’s behavior can change with different task designs, challenging the validity of Piaget’s observations.
Lev Vygotsky (1896–1934):
Focused on the influence of social and cultural interactions on cognitive development.
Although contemporaries, his theories emphasize context and societal impact differently than Piaget.
Social Development:
Higher mental functions emerge from social interactions, contrasting with Piaget’s maturation concept.
Internalization of Knowledge:
Children learn and modify shared cultural knowledge.
Appropriation:
Adaptation of tools occurs uniquely via individual experiences.
Zone of Proximal Development and Scaffolding:
Concepts facilitating supportive learning experiences.
Meltzoff (1977) Findings:
Proposed earlier occurrence of imitation than suggested by Piaget.
Oostenbroek et al (2016) Study:
Tested 106 infants, found no reliable evidence for newborn imitation of actions or sounds, questioning Piaget's timeline.
Conclusions from Research:
The concept of inborn imitation modules should be reconsidered; notions of imitation likely develop around six months, aligning more with Piaget's original hypothesis.
