Success is left and control is right? Intercultural, TMS, and stimulus-varying experiments on the left-hemifield advantage in identifying targets among rapid series of letters

Introduction: In the dual-stream task, rapid sequences of stimuli (10/s) are presented left and right, including two target stimuli. In a number of studies, the second target was found to be identified much better in the left than in the right visual field. Thus, this might be a task that shows the presumed dominance of the right hemisphere for attention-requiring processing in healthy participants. Material and Methods: Based on these preceding studies, here we tested generality and mechanisms of the effect in an intercultural study: Hebrew letters (Israelis) vs. Chinese symbols (Taiwanese) vs. Latin letters (b…
