ABSTRACT
Individuals differ in the kinds of capabilities they bring to the work situation. These capabilities are related to how well or how rapidly they will learn new tasks, how much they will benefit from different kinds of training, and to the level of performance they will eventually achieve (see Fleishman. 1966, 1972). The previous chapter dealt with issues of identifying classes and measures of human capabilities and establishing their linkages with measures of performance in job tasks. The emphasis was on the description and measurement of differences between individuals in human abilities and skills (inter-individual variation) and on the relation of these differences to job performance. The present chapter focuses on some additional issues concerning the relation of human capabilities to task performance. These issues concern variations in capabilities which occur within the individual, which we will call intra-individuai variation.
