This paper is concerned with how Type A and B subjects perceive themselves. Subjects first completed a unidimensional A type measure, then rated themselves and their ideal selves on various personality traits. As expected, Type A was associated with negative self-ratings and high actual-ideal self-discrepancy scores. However, it is argued that self-evaluation in negative terms by Type As is not necessarily synonymous with low self-esteem. Negative self-ratings may be an important factor in the aetiology and maintenance of the Type A behaviour pattern.
