We posited that the form of the joint effects of motivation and ability in traditional performance models are interactive because motivation triggers the use of energy resources required to deploy ability at work. Moreover, we posited that achievement might best represent motivation compared to five other facets of Conscientiousness or global Conscientiousness. In two samples of customer service representatives, achievement interacted with general mental ability (GMA) in predicting task performance, whereas global Conscientiousness and the other five facets did not. This suggests that researchers examining the motivational aspects of Conscientiousness might uncover a more consistent pattern of results for task performance if they focus on the achievement facet. Furthermore, managers might see the highest levels of task performance in certain contexts when hiring individuals based on both achievement and GMA.
