Cognitivism01:17

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process information is...

Introduction to Cognitive Psychology

Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Revisionist Views of Adolescent and Adult Cognition

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are themselves.

Piaget's Theory of Cognitive Development from Childhood into Adulthood

Jean Piaget's theory of cognitive development emphasizes the role of thinking in a child's learning process, suggesting that children are naturally curious about their environment. His approach to development is discontinuous, proposing that cognitive abilities progress through distinct stages, each with unique characteristics. Central to Piaget's theory is schemata—mental structures that allow individuals to understand and interpret the world.

The Nativist Approach01:21

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to exist...
Cognitive Learning01:21

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Area of Science:

  • Cognitive Science
  • Developmental Psychology
  • Computational Neuroscience

Background:

  • Rational constructivism is a modern theory of cognitive development.
  • It posits children actively construct knowledge by integrating new evidence with existing beliefs.
  • This process involves probabilistic inferential learning mechanisms.

Purpose of the Study:

  • To provide an overview of rational constructivism.
  • To explain how the theory accounts for developmental changes.
  • To outline a computational framework and future research directions.

Main Methods:

  • Theoretical overview of rational constructivism.
  • Analysis of empirical patterns in developmental change.
  • Discussion of underlying cognitive mechanisms.
  • Sketching a computational framework.

Main Results:

  • Rational constructivism explains both incremental and radical conceptual changes.
  • The theory integrates evidence with existing knowledge via probabilistic inference.
  • Identifies key cognitive mechanisms driving conceptual revision.

Conclusions:

  • Rational constructivism offers a robust framework for understanding cognitive development.
  • It highlights the role of probabilistic inference in children's theory revision.
  • Further research can refine its computational models and empirical testing.
