Cognitivism01:17

Cognitivism

3.2K
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...

Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

2.8K
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...

Reason and Intuition

7.6K
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...

Lazarus's Cognitive Appraisal Theory01:20

Lazarus's Cognitive Appraisal Theory

2.3K
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

260
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...

Language and Cognition01:27

Language and Cognition

891
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.

Area of Science:

  • Cognitive psychology
  • Mathematical psychology
  • Psychometrics

Background:

  • Determining cognitive architecture, the temporal organization of mental processes, is a long-standing challenge in psychology.
  • Previous methods, like Systems Factorial Technology (SFT), relied on visual assessment of the survivor interaction contrast (SIC).
  • Visual assessment of SIC for identifying parallel or serial processing has limitations.

Purpose of the Study:

  • To introduce and evaluate Bayesian inference methods for cognitive architecture analysis.
  • To compare Bayesian approaches with existing null hypothesis significance tests and visual assessment.
  • To demonstrate the advantages of Bayesian inference in identifying cognitive processing.

Main Methods:

  • Development of parametric and nonparametric Bayesian inference techniques.
  • Application of Bayesian methods to analyze response time distributions.
  • Utilizing the survivor interaction contrast (SIC) within the Systems Factorial Technology (SFT) framework.

Main Results:

  • Bayesian inference methods provide a rigorous alternative to visual assessment for cognitive architecture.
  • Both parametric and nonparametric Bayesian approaches demonstrated advantages in analyzing cognitive processing.
  • The developed methods offer enhanced statistical power and interpretability.

Conclusions:

  • Bayesian inference represents a significant advancement in the empirical and analytical study of cognitive architecture.
  • These methods enhance the ability to accurately determine whether cognitive processes operate in parallel or series.
  • The findings support the broader adoption of Bayesian statistics in cognitive psychology research.
