The present work examined the hostility dimension of Type A by focusing on aberrant cognitions that may play an important role in the anger and aggressive experiences of Type A individuals. Study 1 employed several Type A measures to determine the interrelationships among general hostile cognitions, anger, and Type A characteristics. As predicted, those individuals scoring high on certain Type A measures, namely, the Survey of Work Styles and Framingham Type A Scale, endorsed a large number of general hostile attitudes, and also displayed more frequent and intense anger experiences, relative to those individuals scoring low on these measures. Also as predicted, this pattern was not evident for those individuals scoring high on a third Type A measure, the Jenkins Activity Survey. Study 1 also found that Type As, again as defined by both the Survey of Work Styles and Framingham Type A measures, viewed both themselves and others as generally being more hostile and angry. Study 2 replicated several Study 1 findings, and in addition, examined the specific Type A beliefs and fears outlined in Price's cognitive social-learning model of Type A. In support of Price's model, all of the specific Type A beliefs measured were significantly related to Type A, as assessed by both the Survey of Work Styles and Framingham measures. Further analyses, however, suggested that only those specific beliefs reflecting a cynical philosophical attitude contributed to the prediction of anger in Type As, above and beyond that predicted by general hostile attitudes. Study 2 also provided empirical evidence for a distinction between the cognitive (hostile attitudes) and affective (anger) components of the Type A hostility dimension. Results from both studies were then discussed with regard to the possible role of hostile cognitions in contributing to exhanced anger and aggressive social interactions in Type A individuals.
