Nonverbal behavior of the type A individual

Area of Science:

• Psychology
• Behavioral Science
• Health Psychology

Background:

• The Type A behavior pattern is linked to cardiovascular disease.
• Understanding the nonverbal manifestations of Type A behavior is crucial for early identification and intervention.

Purpose of the Study:

• To investigate the nonverbal behaviors differentiating Type A and Type B individuals.
• To assess the efficacy of nonverbal cues in classifying behavior patterns.

Main Methods:

• Forty-one health professional students were videotaped during waiting, interview, and relaxation conditions.
• Participants were classified as Type A or Type B based on interview audiotapes.
• Nonverbal behaviors (activity, gestures, restlessness) were analyzed and compared between groups.

Main Results:

• Type A subjects displayed significantly more arm movements, exploration, and gestures than Type B subjects across conditions.
• Type A subjects exhibited less stillness and more exploratory behavior during waiting and relaxation periods.
• Nonverbal behaviors alone correctly identified behavior patterns in 71% of subjects, improving classification accuracy.

Conclusions:

• Increased physical activity, restlessness, and gestures are characteristic nonverbal markers of the Type A behavior pattern.
• Nonverbal behaviors provide a reliable method for distinguishing between Type A and Type B individuals.
• These findings support proposed etiologies linking Type A behavior to increased physiological arousal and activity.
