Abstract:
The roles of speed of processing, inhibition, and presentation order in the Trail Making Test (TMT) performance were examined. One-hundred ten undergraduates performed the TMT (1/2 received order Part A-Part B, 1/2 received order Part B-Part A) and also completed computerized tests of inhibitory functioning and speed of processing. Neither speed of processing nor inhibitory functioning affected TMT performance. However, order of presentation significantly affected TMT performance. Presentation order is an important variable to consider in TMT performance.
