Higher Mental Functions of Brain: Learning and Memory

Higher Mental Functions of Brain: Learning and Memory

Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or playing an...

Concepts and Prototypes

Concepts and Prototypes

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Encoding

Encoding

Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

Piaget's Theory of Cognitive Development from Childhood into Adulthood

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.

Piaget's Stage 2 of Cognitive Development

Piaget's Stage 2 of Cognitive Development

The preoperational stage, the second of Jean Piaget's four stages of cognitive development, spans approximately ages 2 to 7 and is characterized by the emergence of symbolic thinking. During this stage, children use language, images, and symbols to represent objects and concepts, enabling them to engage in imaginative and pretend play. This symbolic thinking supports children's ability to perform make-believe actions, such as imagining a broom as a horse or their hand as a phone, blending...

The Nativist Approach

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...

Summary

Children

Area of Science:

Cognitive Development
Concept Acquisition
Child Psychology

Background:

Understanding how children acquire concepts is crucial for educational practices.
Prior knowledge and direct observation of examples are key factors in learning.
The interplay between existing beliefs and new information shapes conceptual understanding.

Purpose of the Study:

To investigate the interaction between children's prior domain knowledge and exemplar observation during concept acquisition.
To examine how exposure to novel exemplars influences the revision of children's conceptual knowledge.
To assess age-related differences in sensitivity to feature covariation and reliance on prior knowledge.

Main Methods:

Three experiments involving 4 to 10-year-old children (N=480 total).

Children were presented with fictitious categories (animals, artifacts, social) with varying consistency to prior knowledge.

Feature co-occurrence judgments were used to assess concept formation and knowledge revision.

Main Results:

Both prior knowledge and exemplar observation independently influenced children's categorization judgments.
Older children (10-year-olds) showed greater sensitivity to observed feature covariation.
Increased exposure to larger categories enhanced the impact of observed feature covariation, reducing reliance on prior knowledge.

Conclusions:

Children's concept acquisition is a dynamic process influenced by both pre-existing knowledge and empirical evidence.
Sensitivity to statistical regularities in the environment increases with age.
Learning environments that provide sufficient exemplars can effectively moderate the influence of prior beliefs.
