- Аннотация: For successful goal-directed behavior in everyday life, it’s crucial to attend relevant stimuli in the visual field while ignoring distractor elements. The objective of this study was to estimate dependence of saccadic LP at the stimulation of dominant and subdominant eye in modified version of oculomotor capture task. Our findings show that when target and distracting stimuli were presented in one visual semifield at the distance of 5 degrees and visual information of the stimulus projected to one hemisphere, LP of voluntary correct saccades was shorter (on 30 ms) but in the same time the number of erroneous automatic saccades was bigger (more then 50%). It can be explained from positions of Posner and Rizzolatty theory of attention from one side and oculomotor competition processes from the other. Saccadic LP were shorter when stimuli were presented to the dominant eye from the left visual semifield in comparison with subdominant eye. Erroneous automatic saccades on distracters appeared in the case of decreasing of LP at 30-40 ms in comparison with correct saccades. We supposed unsuccessful suppress of saccade on distracting stimulus in this case
