Lazarus's Cognitive Appraisal Theory01:20

Lazarus's Cognitive Appraisal Theory

1.5K
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:...

Hindsight Biases

4.2K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

The Availability Heuristic01:08

The Availability Heuristic

6.9K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Cognitivism01:17

Cognitivism

2.6K
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...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

714
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Language and Cognition01:27

Language and Cognition

665
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:

  • Neuroscience
  • Gerontology
  • Epidemiology

Background:

  • Cognitive reserve is a theoretical concept explaining the difference between brain pathology and clinical presentation.
  • It suggests individuals can withstand more neurological damage before showing cognitive decline.
  • Understanding cognitive reserve is crucial for addressing age-related cognitive changes and dementia.

Purpose of the Study:

  • To review the theoretical underpinnings of cognitive reserve.
  • To present key findings from epidemiological and neuroimaging research supporting the cognitive reserve construct.
  • To discuss the implications of cognitive reserve for cognitive aging and dementia.

Main Methods:

  • Literature review of theoretical, epidemiological, and neuroimaging research.
  • Synthesis of evidence supporting the existence and function of cognitive reserve.
  • Focus on studies relevant to cognitive aging and dementia.

Main Results:

  • The concept of cognitive reserve has evolved theoretically.
  • Epidemiological and neuroimaging studies provide substantial evidence for cognitive reserve.
  • Research highlights the role of reserve in mitigating the clinical impact of brain deterioration.

Conclusions:

  • Cognitive reserve is a well-supported construct that helps explain individual differences in cognitive aging.
  • Further research into cognitive reserve can inform strategies for preventing or delaying dementia.
  • The concept has significant implications for understanding and managing cognitive health in older adults.
