Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

1.9K
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...

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...

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

113
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Reason and Intuition01:37

Reason and Intuition

7.2K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Cattell's Theory of Intelligence

7.6K
Raymond Cattell, along with John Horn, made significant contributions to our understanding of intelligence by distinguishing between two types: fluid intelligence and crystallized intelligence.
Fluid intelligence involves the capacity to solve new problems and adapt to unfamiliar situations. It's the type of intelligence individuals use when they encounter a novel problem or puzzle that requires innovative thinking. For instance, figuring out how to operate a new gadget relies heavily on...

Information Processing Approach01:30

Information Processing Approach

321
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Area of Science:

  • Cognitive Science
  • Information Theory
  • Neuroscience

Background:

  • Information theory saw early application in cognition studies in the 1950s, followed by a period of reduced research.
  • Recent decades show a resurgence of interest in applying information theory to cognition, with more rigorous experimental grounding.
  • A key challenge is reconciling the mathematical nature of information theory with the subjective experience of cognition.

Purpose of the Study:

  • To review the historical and contemporary applications of information theory in cognitive science.
  • To explore methodologies for integrating information theory with the study of subjective cognitive phenomena.
  • To highlight diverse applications across various domains of cognition research.

Main Methods:

  • Review of literature on information theory applications in cognitive research over seven decades.
  • Analysis of approaches to bridge the gap between mathematical information theory and subjective cognition.
  • Description of methods focusing on quantifiable cognitive aspects and borrowing conceptual tools from information theory.

Main Results:

  • Demonstration of a revival in the use of information theory for cognitive analysis.
  • Identification of strategies to apply rigorous information-theoretic principles to subjective cognitive processes.
  • Examples of successful applications in neural coding, cognitive control, and predictive coding.

Conclusions:

  • Information theory offers a powerful, increasingly validated framework for understanding cognitive processes.
