Worry was found to be more highly negatively related to examination grades than was Emotionality or pulse rate and worry was more highly negatively related to expectancy than was Emotionality. However, pulse rate was no more highly related to Emotionality than to Worry, suggesting that questionnaire and direct measures of autonomic arousal are…

Considers current knowledge of the evolutionary origin, the development of the structure, the composition, and the morphogenetic regulation of chloroplasts. (AL)

The MAS was administered while drive level was systematically manipulated. Drive state was varied at four levels by the induced muscular tension technique while heart rate (HR) and galvanic skin response (GSR) activity were recorded. No meaningful relationship between MAS scores and HR and GSR activity was observed. The intercorrelation between HR…

This study is based upon a doctoral dissertation completed at the University of Southern California, 1965.

Examines teaching-style preference as a function of individual differences in physiological arousal/stimulation seeking. Reports responses of 29 teachers to the Sensation Seeking Scale, the Two-Flash Threshold, and a questionnarie. Shows low-arousal teachers tended to prefer a "traditional style" and high-arousal teachers tended to…

Running can be used effectively to produce positive physiological and psychological changes, including cardiovascular and physical fitness, reduction of anxiety, and more effective management of stress. (CJ)

The neural networks of several invertebrate animals are currently being studied for clues to cerebral function. The major goal of the studies is an understanding of the neural mechanisms behind learning. Organisms used, examples of research studies, and implications are discussed. (Author/JN)

The article reviews the physiological studies (excluding electrocortical and electroencephalographic literature) that have been done on nonhyperactive learning disabled (LD) youngsters. The evidence reviewed indicates some degree of attentional deficit in LD children but does not necessarily imply brain damage or brain dysfunction. (Author/CL)

Compared physiological effects of progressive relaxation, alpha feedback, and a no-treatment condition. Nonpatients showed more psychophysiological habituation than patients in response to hearing very loud tones and to reaction time tasks. Patients showed greater physiological response to relaxation than nonpatients. After relaxation, autonomic…

Sleep positions, particularly the full fetal position, appear to be related to California Psychological Inventory (CPI) variables of sociability, sense of well being, achievement by conformance, femininity, and social maturity. (Author)
