The effects of nicotine and extraversion on self-report, skin conductance, electromyographic, and heart responses to emotional stimuli.

摘要: Abstract Eysenck's hypothesis that nicotine reduces emotional reactions by reducing cortical arousal and Gilbert's alternative this effect of occurs because its tendency to increase perceptual thresholds and/or reduce muscular tension were tested having 48 habitual smokers smoke either high (1.3 mg) or low (0.2 cigarettes just prior viewing a series videotaped emotion-producing scenes. Consistent with predictions, the skin conductance response magnitudes subjects who smoked high-nicotine significantly smaller than those low-nicotine cigarettes. On other hand, contrary there was no significant interaction between extraversion for self-report responses. Day 2, but not 1, reduced self-reports perceived startle did cause perception increased heart activity in spite an actual rate.
