Optimal Arousal Theory01:23

Optimal Arousal Theory

228
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.

Cognitive Theories: Schachter-Singer Theory of Emotion

468
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.

According to this theory, when an individual experiences...

Lazarus's Cognitive Appraisal Theory

287
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:...

Cognitive Theories: Lazarus Mediational Theory of Emotion

954
Richard Lazarus' cognitive mediational theory highlights the pivotal role of cognitive appraisal in shaping emotional responses. According to this theory, the evaluation of a stimulus — based on personal values, goals, beliefs, and expectations — mediates the emotional response. This appraisal process is immediate and often occurs unconsciously, influencing the intensity and nature of the resulting emotion.

Summary
This summary is machine-generated.

Presleep arousal-cognitive and sleep onset latency predict posttrauma nightmares. Physiological arousal was higher on nightmare nights, supporting therapies targeting these factors.

Area of Science:

  • Psychology
  • Sleep Science
  • Trauma Studies

Background:

  • Posttrauma nightmares are common after traumatic events.
  • Previous research identified potential predictors like presleep arousal and sleep onset latency, but with limitations.
  • Replication and generalizability are needed in diverse trauma populations.

Purpose of the Study:

  • To replicate findings on predictors of posttrauma nightmares.
  • To investigate presleep arousal (cognitive and physiological) and sleep onset latency.
  • To examine these predictors in male inpatient veterans with mixed trauma histories.

Main Methods:

  • 15 male inpatient veterans participated.
  • Collected data via initial assessments and 7-day pre/post sleep diaries.
  • Utilized portable objective measures for sleep quality and presleep arousal.

Main Results:

  • Presleep arousal-cognitive and sleep onset latency significantly predicted nightmare occurrences.
  • Presleep arousal-physiological was notably higher on nights with nightmares.

Conclusions:

  • Findings replicate the role of presleep arousal and sleep onset latency in triggering posttrauma nightmares.
  • Results suggest potential therapeutic targets for posttrauma nightmares.
  • Therapies focusing on presleep cognitions, sleep onset latency, and arousal may be beneficial.
