Twenty Type A (coronary-prone) and 20 Type B (coronary-resistant) college aged females were compared on alpha production, time estimation, locus of control, androgyny, self concept, and state and trait anxiety. Type B females spent significantly more time, during a 10 minute recording session, in alpha at both the 20uv and 30uv levels than Type A females (t_ = 3.91, p < .001; t = 3.09, p < .01). Additionally, Type B females had a greater number of discrete periods of alpha activity at both the 20uv and 30uv levels (t = 1.706, p < .05; t = 2.37, p < .025). Differences were found between Type A's and Type B's on three of four unfilled time estimation tasks: 7 sec (t = 2.59, p < .01), 15 sec (t = 3.86, p < .0005), and 30 sec (t = 5.00, p < .0005). In each case, Type A's estimated significantly shorter intervals; however, no differences were observed between the two groups on a filled time estimation task. A's and B's did not differ in terms of locus of control. A greater proportion of Type A females were categorized as androgynous than were Type B females. Type A females were found to be significantly more certain of their self perceptions and more defensive than Type B's. There were no differences between Type A and B females on state and trait measures of anxiety.
