Cognitive Dissonance01:38

Cognitive Dissonance

33.0K
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...

Optimal Arousal Theory01:23

Optimal Arousal Theory

265
The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Self-Discrepancy Theory

18.4K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Cognitive Theories: Schachter-Singer Theory of Emotion

556
Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences...

Deindividuation00:57

Deindividuation

26.8K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Social Facilitation01:04

Social Facilitation

32.4K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Summary
This summary is machine-generated.

Cognitive dissonance arousal is linked to less exercise, while dissonance reduction is linked to more exercise. These findings suggest dissonance processes can be adaptive and offer insights into increasing physical activity.

Area of Science:

  • Psychology
  • Behavioral Science

Background:

  • Cognitive dissonance theory explains discomfort from conflicting beliefs or behaviors.
  • The action-based model posits dissonance influences behavior.
  • Understanding dissonance's role in health behaviors like exercise is crucial.

Purpose of the Study:

  • To test predictions from the action-based model of cognitive dissonance theory.
  • To investigate the relationship between dissonance arousal, dissonance reduction, and effective exercise behavior.
  • To explore if dissonance processes predict exercise behavior independently of other traits.

Main Methods:

  • Three studies measured individual differences in dissonance arousal and reduction using questionnaires.
  • Effective behavior was quantified through GPS-tracked cycling (Study 1) and self-reported exercise frequency (Studies 2-3).
  • Statistical analyses controlled for approach/avoidance motivation and life satisfaction.

Main Results:

  • Higher dissonance arousal correlated with lower exercise levels.
  • Higher dissonance reduction correlated with higher exercise levels.
  • Dissonance processes significantly predicted exercise behavior, even after accounting for other psychological traits.

Conclusions:

  • Dissonance processes appear to be adaptive, influencing behavior in potentially beneficial ways.
  • The findings suggest strategies targeting dissonance reduction could enhance exercise engagement.
  • Further research may identify mediators within exercise commitment literature.
