Piaget's Cognitive Development Theory

Understanding Cognitive Development

• Cognitive development explores how learning, thinking, and problem-solving skills evolve.
• Jean Piaget proposed universal stages for intellectual growth, while Lev Vygotsky emphasized sociocultural influences.
• Modern research includes information-processing theory and intelligence testing as factors.
• Cognitive development insights help us understand how intellect grows throughout life.

Piaget's Theory

• Jean Piaget created genetic epistemology by combining zoology and epistemology
• Genetic epistemology studies how knowledge develops
• Piaget used observations of his children and a clinical method to study how children solve and interpret problems

Intelligence

• Piaget viewed intelligence as an adaptive function for balanced thoughts and environment, termed cognitive equilibrium.
• Cognitive disequilibrium occurs when new experiences challenge existing understanding.
• Equilibration is the process of adjusting thinking to resolve disequilibrium, fostering growth.

Child as a Constructivist

• Piaget emphasized children actively construct knowledge, interpreting the world through their cognitive development
• Attributing intentions to inanimate objects shows developing cognitive frameworks
• Piaget's work shaped our understanding of how children think, learn, and adapt

Key Terms

• Genetic epistemology is the study of the development of knowledge
• Intelligence is a basic life function enabling adaptation to the environment
• Cognitive equilibrium is a balanced and harmonious relationship between thought processes and the environment
• A constructivist gains knowledge by acting on objects and events

Gaining Knowledge

• Cognition refines and transforms mental structures, called schemes.
• Schemes, unobservable thought patterns, organize our knowledge.

Key Processes of Cognitive Growth

• Organization is the process is organizing existing schemes into complex systems
• Adaptation is the process of adjusting to new experiences

Adaptation Types

• Assimilation incorporates new experiences into existing schemes
• Accommodation modifies existing schemes to account for new experiences

Equilibration's Role

• Assimilation and Accommodation promote cognitive equilibrium
• Cognitive conflict prompts adjustment and restores balance.
• This cycle allows increasingly complex and accurate understandings of the world.
• Organization and adaptation demonstrate that cognitive growth is an active, dynamic process.

Stages of Cognitive Development

• Piaget identified 4 invariant stages
• Order is the same for all children, but ages of transition vary
• The stages are Sensorimotor, Preoperational, Concrete Operational, and Formal Operational

The Sensorimotor Stage

• Sensorimotor stage happens between birth and 2 years
• Infants learn through sensory experiences and actions, developing object permanence

The Preoperational Stage

• The Preoperational Stage happens between 2-7 years
• Children develop symbolic thinking and language.
• Children still struggle with logic and perspective-taking, also known as egocentrism

The Concrete Operational Stage

• Concrete Operational Stage happens between ages 7-11
• Logical develops, allowing children to understand concepts like conservation and classification

The Formal Operational Stage

• Formal Operational Stage happens at 11+ years
• Abstract and hypothetical thinking emerge
• This stage allows problem-solving and scientific reasoning

Constructivism

• Children actively build knowledge, influencing education and learning approaches.

Sensorimotor Subtages

• Reflex Activity (Birth–1 Month): Infants rely on innate reflexes, adapting to new experiences
• Primary Circular Reactions (1–4 Months): Infants repeat pleasurable activities centered on their own bodies
• Secondary Circular Reactions (4–8 Months): Babies interact with external objects, discovering actions that produce interesting results
• Coordination of Secondary Reactions (8–12 Months): Infants combine actions to achieve goals, marking goal-directed behavior
• Tertiary Circular Reactions (12–18 Months): Babies experiment using trial-and-error to achieve effects
• Symbolic Problem Solving (18–24 Months): Ability to solve problems mentally emerges, showing symbolic thought
• Infants at transition from reflex-driven to problem solvers who think symbolically

Early Imitation

• Infants cannot imitate new actions until 8–12 months
• Imitation is imprecise, such as opening the whole hand instead of bending a finger
• Infants imitate actions immediately, but not precisely

Voluntary Imitation

• Between 12 and 18 months, imitation is more precise
• Infants imitate specific actions with more accuracy

Deferred Imitation

• Ability to reproduce a behavior observed earlier
• Piaget noted that this ability occurs around 18–24 months
• Demonstration of a child storing a mental image of a behaviour to imitate later
• It suggests older infants can mentally represent observed behaviors

Critiques of Piaget's View

• Deferred imitation can occur much earlier (6-month-olds imitating actions 24 hours later)
• Toddlers imitate actions observed up to 12 months prior, challenging Piaget’s timeline

Imitation Conclusion

• Piaget established imitation's role in cognitive development
• The ability to imitate and represent emerges earlier than suggested

Object Permanence

• Understanding objects exist when not visible, a milestone in the sensorimotor stage.

Early Infancy

• Infants don't search for hidden objects
• They think objects exist only if they are seen or interacted with

Emerging Object Concept

• Infants start retrieving partially concealed objects
• From an infant's perspective, out of view may mean not existing.

A-not-B Error

• Clearer signs of object permanence emerge, but it is not yet complete
• A-not-B error is when infants search in the old location after seeing movement

Improving Object Concept

• Toddlers improve object permanence skills. They will search for objects where they last saw them.

Full Object Permanence

• Toddlers fully understand invisible displacements and are able to search in a different location
• Toddlers mentally represent objects and understand they exist even when not seen

Object Permanence Conclusion

• Developing object permanence shows a cognitive shift
• Children realize that objects exist independently of perception
• The world becomes more sophisticated with mental representations

Challenges to Piaget

• Piaget's profoundly impacted developmental psychology, especially for understanding sensorimotor development
• Newer studies show that there are more advanced cognitive abilities than proposed
• Theory theories and neo-nativism are major theoretical approaches that critique Piaget

Neo-Nativism

• Infants are born with innate knowledge about the physical world, part of genetic inheritance
• Claim is that infants have inherent understanding of object permanence earlier than Piaget thought
• Infants can construct knowledge innately

Infant's Early Knowledge

• Research shows that infants as young as 3-4 months show some understanding of object permanence.
• Infants may have the ability to represent and remember actions much earlier than Piaget suggested,

Wynn's Experiment

• Karen Wynn conducted an experiment to assess infants' understanding of basic arithmetic.
• Infants saw possible and impossible outcomes and were surprised by the impossible
• Even young infants may understand numbers and arithmetic

Arithmetic Abilities

• Infants may have a better number and arithmetic understanding than the sensorimotor stage indicates

Alternative Interpretations

• Infants might react to substance amount or property changes, not numbers.

Neotivism Conclusion

• Wynn's experiment and neo-nativists challenge the gradual construction of knowledge in Piaget's Inancy notion

Theory Theories

• Hybrid approach combining neo-nativism and Piagetian constructivism
• Infants start with innate knowledge but actively construct theories about the world through experiences.

Key Ideas of hybrid approach

• Innate Preparedness: Infants have basic knowledge that is not fully developed.
• Constructing Theories: Infants test and modify theories about the world, like scientists.
• Theory Change: Crisis experiences update children’s theories, like Piaget's equilibration.

Cultural Similarities of hybrid approach

• Gopnik and Meltzoff suggest evolutionary development enables similar theories across cultures

Preoperational Stage Summary

• The Preoperational Stage (2-7 years) it is characterized by symbolic thought
• It is the ability to use words and images to represent objects and experiences

Representational Insight

• Key concept is representational insight

Hallmarks of Preoperational Stage Summary

• Development of language
• Pretend play which is imaginative

Dual Representation Highlights

• 3-year-olds used a scale model to find a toy, showing representational insight
• 2.5 year-olds struggled but could use a photo
• Factors are that children focus on the model a symbol and not as interesting object

Symbolic Reasoning

• It is still fragile during early childhood, and improves between ages 2.5 and 3.

Preoperational Reasoning Deficits

• Animism: Attributing lifelike qualities to inanimate objects
• Egocentrism: Difficulty understanding others' perspectives in the three-mountain task
• Appearance/Reality Confusion: Trouble distinguishing looks from reality
• Conservation Failure: Not understanding quantities remain the same
• Conservation failure occurs through centration and lack of reversibility
• Cognitive limitations mean young children rely on intuition instead of logical reasoning

Reconsidering Piaget

• Preschool children's cognitive abilities may have been underestimated
• Those abilities involve logical reasoning and egocentrism

Egocentrism Revisits

• Piaget's three-mountain task was difficult
• Flavell's study showed recognition of different perspectives in simpler tasks
• Deception activity means understanding the theory of mind

Children's Thoughts

• Their thoughts are more capable of perspective-taking and logical thought than originally believed

Animism

• Displayed animism stems from reasonable assumptions (e.g., if something moves, it must be alive).
• 3 year olds displayed animism more

Conservation

• 4 year olds even be trained in this concept

Reasoning Key Takeaway

• Reasoning improves with guidance
• It is improved with identity training

Theory of Mind (TOM)

• TOM means that knowing people have thoughts, beliefs, and desires that may vary
• Belief-Desire Reasoning (Wellman, 1990): People's actions driven by beliefs and desires, in falsehoods
• False-Belief Task (Jorge’s Chocolate Test) causes failure for 3 year olds but succeed with 4-5 yr olds

Developing Theory of Mind

• Collaboration & Deception: Planning tricks improves skills

Cognitive Development

• It has roots in social interactions, play, and family dynamics.
• Modern research indicates children viewed as highly egocentric by Piaget develop sooner

Re-evaluating Piaget’s View of Preschoolers

• His tests required verbal justifications that young children struggled with
• Preschoolers understood more than they could articulate, distinguishing living from non-living things.
• Logic appears with simpler and more familiar scenarios

Cognitive Abilities

• Performance might stem from task complexity, difficult explanations, and unfamiliarity

Operational Stage

• children mastered mass but not volume

Piaget's Underestimation

• Piaget correctly identified differences but underestimated abilities due to testing methods
• Piaget explained cognitive development as gradual, not an immediate shift

Development Skill Acquisition

• Around age 6-7, it allows for learning structure and arithmetic

Summary of Preoperational Stage

• Key concept is representational insight
• It is ability to to use words, images, to represent objects
• Factors are children focus on the model rather than an object.
• Animism: Attributing lifelike qualities to objects

Piaget Formal-Operational Stage

• It beings around 11-12
• Abstract, logical, and systematic thinking is a characterization

Deductive Reasoning

• Ability to think and analyze
• Younger are reliant on concrete
• Example: Solve with mathematical equations

Inductive Reasoning

• General conclusions from specific
• Relate to scientific method

Thinking Pendulum

• Formal-Operational
• Younger relies on correct solutions for concrete

Significance of Formal Operational Stage

• Allows the potential for critical thinking, advanced, and problem solving
• Requires training for concepts to improve concepts

Formal-Operational Key Implication

• The formal-operational stage marks the shift from experience-based thinking to abstract and hypothetical reasoning.
• Prepares people for complex reasons, academics, and real-world problems

Formal-Operational Stage Influences

• Contributes to adolescent egocentrism, marked teens becoming more self conscious
• Lead to potential conflicts by questioning, and frustration

Development of Formal Operations

• Piaget notes transition between ages 11-18

Key Evaluation of Piaget

• Contributes to knowledge, Active Learners, & Approach

Development Stages Broad

• Stages were broad
• Inspired cognitions, education etc
• Extensive research and insights resulted
