Cognitive Learning01:21

Cognitive Learning

1.5K
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 Schemas01:30

Impact of Schemas

265
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,...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

1.4K
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...

Interference and Decay01:16

Interference and Decay

567
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Higher Mental Functions of Brain: Learning and Memory

2.3K
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...

Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

1.3K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Summary

Human memory strategically allocates cognitive resources to maximize rewards, not just encode salient items. This adaptive process explains complex reward influences on memory, accounting for cognitive constraints.

Area of Science:

  • Cognitive Neuroscience
  • Computational Neuroscience
  • Psychology

Background:

  • Human episodic memory selectively encodes important information.
  • Reward typically enhances memory, but this relationship is complex and context-dependent.

Purpose of the Study:

  • To develop a computational model explaining how cognitive constraints and reward environments interact to shape memory encoding.
  • To reconcile empirical findings on reward's influence on memory, including non-monotonic effects and contextual modulation.

Main Methods:

  • Developed a parameter-free computational model of memory encoding.
  • Validated model predictions against three experimental datasets.
  • Focused on optimal adaptation under cognitive constraints.

Main Results:

  • The model successfully explains why high-reward items lack a memory advantage in certain contexts.
  • Demonstrated how reward context and anticipation influence memory encoding strategies.
  • Showed that memory encoding is an active, metacognitively controlled process.

Conclusions:

  • Memory encoding is an active allocation of limited cognitive resources to maximize cumulative rewards.
  • The model provides a unified account of reward's complex influence on memory.
  • Findings highlight the role of metacognitive control in memory formation.
