DOES THE HEMISPHERE STIMULATED PLAY A SPECIFIC ROLE IN DELAYED RECOGNITION OF COMPLEX ABSTRACT PATTERNS - TACHISTOSCOPIC STUDY

Abstract visual patterns were projected tachistoscopically to the left and right striate cortex of 50 undergraduates. After a delay of 0, 5, 15, 30 and 60 sec the recognition of the target was checked without time constraints on a six-alternatives set. The result was that stimuli projected to the left striate area at a 15 sec retention interval were better recognized than those projected to the right, whereas the opposite was true when the stimuli were recognized at a 60 sec delay. © 1979.
