Hemispheric interaction in the Stroop task

Abstract
The aim of this study was to explore the efficiency of solving the Stroop task under different conditions of stimulus presentation. Fifty psychology students participated in the experiment. The subjects were asked to solve two versions of the Stroop test, a congruent and an incongruent one, in five different conditions of stimulus presentation - two types of within-hemisphere presentation (to the left or right visual fields), two types of inter-hemisphere presentation and central presentation. Response time and accuracy were registered. The results confirmed the Stroop effect, as well as differences in the efficiency of solving the task under different conditions of stimulus presentation. Bilateral presentation and unilateral presentation to the right visual field were shown to be the most efficient. A significant interaction between the two variables of problem complexity and type of presentation was also found, and it was due primarily to the results in central presentation condition. This condition was the most efficient for the congruent task, but least efficient for the incongruent task. The results have not confirmed the main hypotheses of this study, due probably to the complexity of the investigated problems, as well as the existence of many relevant factors that were not sufficiently controlled.
