“…Like the first experiment, the design allowed for a consideration of the effects of I-eval and E-eval conditions in the case of easy and hard tasks. Additionally, Experiment II introduced two new independent variables, sex and need achievement (nAch) (Atkinson & Feather, 1966;McClelland, Atkinson, Clark, & Lowell 1953; see also Maehr & Sjogren 1971). These two other independent variables could not be used simultaneously in a four-way design because the measure of nAch chosen for this study (Mehrabian 1958) requires a different form of the instrument for males and females.…”
