Arousal and Cognition: Word Arousal and Visual Search
Perceptual and Motor Skills, 1976The influence of target-word affective properties on information processing time in a high speed visual-search task was studied. The 24 words were embedded in random-letter matrices, with one word per matrix. Subjects (5 male, 5 female) were tested. Words extreme on emotionality (positive vs negative affect) yielded significantly longer latencies than ...

Frontiers in Bioscience, 2003
The brain contains autochthonous neural systems that evoke waking from sleep in response to sensory stimuli, prolong or enhance arousal in response to special stimuli, and also generate and maintain wakefulness regardless of sensory stimuli during the active part of the day.

Stress is considered to be an important cause of disrupted sleep and insomnia. However, controlled and experimental studies in rodents indicate that effects of stress on sleep-wake regulation are complex and may strongly depend on the nature of the stressor.

Arousal and Arousability in Repeated Isolation Experiences
Perceptual and Motor Skills, 1987Four young adult college men provided estimates of 30 min. during three spaced trials of 6 hr. each Mean heart rates before and after estimates were significantly different. Mean preestimates of rates by trial were higher but postestimate rates were similar over trials. A stimulating event can arouse though the subject is relaxed.

Trait Arousability-An Alternative to Trait Arousal
1987This chapter presents the theoretical rationale and procedures used to develop a questionnaire measure of individual differences in stimulus screening and associated differences in arousability. The rationale for the scale is presented in some detail because of the novelty of the concept of stimulus screening and because of the complex set of ...

AROUSAL GRADIENT AND PERFORMANCE
Perceptual and Motor Skills, 1990A two-dimensional view of arousal was operationalized by controlling gradient and intensity of exercise-arousal in three experiments with 160 male subjects. In all three experiments, significant cognitive performance decrement occurred at moderate intensities of arousal during, or shortly after, steep-gradient arousal increases. These results could not

A two-dimensional view of arousal was operationalized by controlling gradient and intensity of exercise-induced arousal in two experiments with 80 undergraduate men. Significant cognitive performance decrement on a visual-search task occurred at high arousal intensity in the steep-gradient arousal conditions.
