MINI-CPT: A continuous performance test program for the Tandy PC-8 Pocket Computer

MINI-CPT programs the miniature PC-8 computer (2K RAM) to administer a continuous performance test. After training to criterion, MINI-CPT presents a randomized series of 360 stimuli at 1-sec intervals. Upon completion of the 6-min task, statistics including reaction time (RT) mean, standard deviation, and distribution; errors of omission and commission; a percent correct score adjusted for response bias; and RTs for each of the 90 targets are displayed or printed via a PC-3 printer. User options include selecting immediate RT feedback, limiting the task to 3 min, and designating the randomization seed to generate replicable stimulus sequences. MINI-CPT provides a portable, inexpensive measure of attention suitable for use in field research in attentional-deficit disorders, circadian rhythm disturbances due to shift work or jet lag, and, in neuropsychological rehabilitation, as a directed-attention training device with immediate feedback.
