This article examines the idea that there is a dynamic link between 2 quite separately formulated typologies of personality—namely the Kleinian typology according to paranoid-schizoid (PS) and depressive positions and the Type A-Type B typology proposed by M. Friedman and R. Rosenman in 1959. The article provides an account of the nature of these 2 typologies and examines the nature of the convergence that specifically exists between Type A personality and the PS position. The highly pressured, competitive, covertly and overtly hostile, as well as highly conscientious and cynical, propensities of the Type A personality are examined as manifestations of PS functioning. The traits are manifestations of the kinds of defenses that occur during the PS position—namely splitting, denial, and omnipotence.
