Interference between stimulus and response processing demands within a cerebral hemisphere.

TL;DR: Green et al. as mentioned in this paper examined the kind of interaction that occurs between stimulus and response processing demands within a cerebral hemisphere, with particular interest in whether interference between such demands occurs, in which subjects used a manual response to indicate whether a pair of stimuli, presented in the left, right, or center visual field, were the same or different, according to specified criteria.

Abstract: Interference Between Stimulus and ResDonse Processing Demands Within a Cerebral Hemisphere September, 1977 Joanne Green, B.A., Tufts University M.S., University of Massachusetts Ph.D., University of Massachusetts Directed by: Arnold D. V7ell The present research was designed to examine the kind of interaction that occurs between stimulus and response processing demands within a cerebral hemisphere, with particular interest in whether interference between such demands occurs. Four experiments were performed, in which subjects used a manual response to indicate v;hether a pair of stimuli, presented in the left, right, or center visual field, were the same or different, according to specified criteria. The presence of interference was inferred if response time was slowed when the stimulus v/as projected to the hemisphere controlling the response. Interference was observed in performance of a visuospatial , physical identity letter matching task, using either a bimanual or unimanual choice response. Interference was also observed in perform.ance of a verbal, letter name matching task, using a unimanual choice response, but not in perform.ance of a verbal,
