Abstract
The present study investigated laterality effect of visuospatial attention using a visual statistical learning. In a learning phase, two different unfamiliar letters were simultaneously presented to each of bilateral visual fields. Triplets consisting of three unfamiliar letters, which were always presented in the same order, appeared in the three visual-field conditions: a left (LVF), right (RVF) and bilateral visual-fields conditions (BVF). Participants were instructed to silently count a triangle occasionally presented to a fixation point. Immediately after the learning phase, the test phase were conducted. Recognition speed for each letter consisting the triplet was measured using a rapid serial visual presentation (RSVP) paradigm, in which participants had to detect a target within a stream of stimuli. The reaction time obviously decreased with the triplet position in the RVF condition relative to other conditions. These results suggested that attentional resources is dominantly distributed task irrelevant stimuli in right visual space.
