Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Language and Cognition

820
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.

Cognitive Therapy01:25

Cognitive Therapy

1.3K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Cognition and Behavior

389
Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

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...

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...

Summary
This summary is machine-generated.

Adults exhibit a default global cognitive processing mode, similar to children, which becomes less precise in demanding situations. This global mode shifts to a controlled, analytical processing when greater discrimination is required.

Area of Science:

  • Cognitive Psychology
  • Developmental Psychology

Background:

  • The All or None Hypothesis describes a global, imprecise cognitive system.
  • Evidence exists for this in children, but not extensively in adults.

Purpose of the Study:

  • To investigate the All or None Hypothesis in adult populations.
  • To determine if corollaries apply to middle-aged adults.

Main Methods:

  • Evaluated 73 adults (ages 18-57).
  • Utilized a modified arrows test to analyze three corollaries of the hypothesis.

Main Results:

  • Results support the analyzed corollaries in adults.
  • Adults default to a global, less differentiated response mode.
  • This global mode is replaced by controlled processing for analytical tasks.

Conclusions:

  • Adult cognitive systems operate in a global, default mode.
  • Cognitive processing shifts to a controlled, differentiated mode when needed.
  • The All or None Hypothesis appears applicable to adult populations.
