Twenty‐four undergraduates were assigned to two groups to determine if the T3 computerized finger‐tapping task could discriminate between persons motivated to perform optimally and those motivated to perform sub‐optimally. Group HI was instructed to simulate a head‐injured person undergoing an insurance evaluation, whereas group J was instructed to simulate an applicant undergoing a job interview. Group HI tapped slower, demonstrated less fatigue, less similarity between their right‐ and left‐hand performance, and showed less of a speed advantage for the preferred hand. While group HI displayed less variability for the non‐preferred hand, the groups did not differ on variability for the preferred hand. Therefore, the T3 successfully discriminates on multiple measures between persons simulating optimal and sub‐optimal performance. © 2003 Wiley Periodicals, Inc. J Clin Psychol 59: 123–131, 2003.
