Abstract
The aim of this study was to investigate the effect of different FPs duration 0.25, 0.5, 1, 1.5 and 2 seconds on simple and three choice visual RT performances in both simple and complex task. Participants were 351 right-handed male University students. The screening two choice RT test were administered and then 40 subjects were chosen and assigned on the base of block random allocation in two groups. Data gathering tool was researcher-made software that reliability and validity were confirmed. Data were analyzed by analysis of variance (ANOVA) with repeated measures and independent t-test. The results showed that simple RT was a significant differences between five FPs duration in simple task (p<0.005). Three choice RT was a significant differences between five FPs duration in simple task (p<0.001).Simple RT was significant difference in the five similar FPs durations in simple task compared to the complicated task (p<0.001).Three choice RT was significant difference in all similar FPs durations in simple task compared to complex task with the except for 1.5 second FP (p<0.001).It was concluded that the most of FPs duration effects were on simple RT and three choice RT in simple task and this effects on three choice RT more than simple RT.
