The current study is the first reported use of both the other-rated and the self-rated forms of the Neuropsychology Behavior and Affect Profile (NBAP; Nelson, Satz, & DʹElia, 1994). Twenty-eight adult patients who were 7 to 27 months post predominantly mi

Recently, much research has focused on the development and utilization of various motivational assessment techniques designed to identify malingered neuropsychological test performance. Other findings have suggested a strong link between the motivation of the subject and the degree to which the neuropsychological test results validly represent the individualʹs true level of functioning. However, the majority of the empirical work in this area has focused on only one end of the motivational spectrum, decreased motivation. In order to obtain a more complete assessment of the relationship between motivation and neuropsychological of test results, the present study involved an evaluation of the effects of motivational differences on test performance across three levels of motivation: high, low, and standard in 75 head-injured college students. Results supported past research showing significant decreases in test performance by participants given individual financial incentives ($25.00) to perform poorly. Additionally, the sensitivity of several malingering tests to this response set was supported. However, no reliable differences were found on neuropsychological or motivational tests between the group given financial incentives ($25.00) to perform well and the standard instruction group.
