Sixty male faculty and student volunteers were tested for autonomic nervous system ANS reactivity under relaxed, active task Stroop color-word problems combined with a gono go vigilance task and passive task cold pressor conditions, and completed questionnaires on Type A characteristics and behaviorssymptoms often associated with stress. Physiological variables including frontails muscle tension, skin temperature, heart rate, R-P interval and skin potential were measured over 30 second trial intervals for 5 trials Relaxl, Active Task, Relax 2, Passive Task, Relax 3 per session and 2 Test-retest reliabilities for these variables ranged from r.45 to r.71. As predicted, Type A characteristics were associated with greater task induced ANS reactivity p less than .05. The study also examined specific ANS reactivity patterns such as task induced heart rate changes. Author
