ABSTRACT
Up to now the focus has been on the interaction between participation and personality. Another interaction was also explored in the present study—that between ability and motivation variables in the determination of job performance. While ability and motivation have long been regarded as conceptually separable determinants of performance, their joint effects have seldom been studied. Traditionally the former variable has been within the province of psychologists interested in problems of selection and placement, while the latter has been studied most frequently by social psychologists interested in interpersonal relationships within organizations. Seldom have both ability and motivation been used together to predict performance. The implicit assumption seems to have been that the effects of each variable are independent and do not require simultaneous study.
