Cognitive Learning

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...

Impact of Schemas

Impact of Schemas

Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Social Facilitation

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Role of Cerebellum and Prefrontal Cortex in Memory

Role of Cerebellum and Prefrontal Cortex in Memory

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Implicit Memories

Implicit Memories

Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.
One key aspect of implicit...

Area of Science:

Cognitive Psychology
Expert Performance Studies

Background:

Expertise in complex domains like chess relies on both general skill and specialized knowledge.
Understanding how domain-specific knowledge influences expert cognition is crucial.

Purpose of the Study:

To investigate the impact of specialization on chess players' recall and problem-solving abilities.
To compare performance within and outside an expert's area of specialization.

Main Methods:

Assessed expert chess players' recall of positions and problem-solving skills.
Compared performance on stimuli within versus outside their specialization.
Analyzed problem-solving strategies (depth vs. breadth of search).

Main Results:

Players performed significantly better on tasks within their specialization.
Specialization effects on recall and problem-solving were substantial, overriding general skill differences.
Problem-solving strategies adapted: deeper search for specialized problems, broader search for non-specialized ones.

Conclusions:

Domain-specific knowledge and memory of experiences are critical for expert problem-solving.
General-purpose problem-solving strategies may be less effective than specialized knowledge.
Teaching context-independent strategies to future experts might be inefficient.
