Abstract
From a pool of female college students who volunteered and took the modified Jenkins Survey (Form T), 22 subjects were classified as Type A (scores of 11 or above) or as Type B (scores of 5 or below). Subjects were subdivided into six groups (Type A/B) as control, biofeedback/relaxation, or biofeedback/relaxation with competitive set. EMG (frontalis muscle tension) scores were assessed over five blocks of five trials. Pre- and postanxiety self-report measures were also obtained for all subjects. Analysis suggested an interaction of Type (A or B) with set (competitive only). EMG scores indicated that Type A subjects were more tense and remained more tense than Type B subjects under a competitive set. EMG tension scores diminished over trials for all groups. Pre- and postanxiety scores indicated a reduction in self-reported state anxiety for all groups combined, but no differential reductions with respect to group, condition, or set.
