title: Task-related arousal of type A and type B persons: level of challenge and response specificity.
abstract: To determine whether different levels of challenge had differential effects on the arousal levels of Type A and Type B persons, 30 Type A and 30 Type B male subjects worked on an intelligence test task (digits backwards recall) that was easy, moderately difficult, or extremely difficult. Arousal was measured in terms of systolic blood pressure, diastolic blood pressure, pulse rate, pulse volume, skin resistance, and subjective arousal. Results indicated that while working on the extremely difficult task, the Type A subjects evidenced reliably higher systolic blood pressure than did the Type B subjects (p = 0.1; difference = 7.52 mm of Hg) and that there were not reliable differences between the subjects in systolic blood pressure at other levels of challenge or on other measures of arousal.
