Background & Aims: The aim of this study is to investigate the effect of strop on the psychological refractory period.

 Materials & Methods: The present study is of semi-experimental. 20 students of Chamran University of Ahwaz, chosen in reach; participated in the study with average age of 23/45±1/45. Each of the participants did a test of strop effect dual task within four intervals of 50, 100, 300, 900 ms between asynchronous onset of the tasks in both congruent and incongruent conditions.

Results: The results of repeated measurement test with (p>0/05) significant indicate that response time of the congruent stimulant is quicker compared with the incongruent one. In short intervals, the automatic process of reading the word had no overlap with the process of naming the word.

Conclusion: Therefore, strop effect in short intervals was not effective and the incongruent condition of strop effect makes the analysis of stimulant complex during the phase of choosing the response. Intra-group difference and internal inconsistency of two stimulants within the sequence of congruent and incongruent dual task increased the response time of the second stimulant. So, increase in the complexity of the first stimulant causes the longest delay of the second one.

Keywords: stroop effect, Reaction Time, Dual task, Sectional attention, congruent, incongruent
