The Effect of Analytic Versus Holistic Encoding Instructions on Hemispheric Superiority

Abstract

A modification of the tachistoscopic letter detection task employed by Neisser (1963) was utilized to examine hemispheric differences in employing analytic and holistic processing strategies. Stimulus arrays designed to elicit either serial or parallel processing sets were presented to the right hemisphere-left visual field (RH-LVF) or to the left hemisphere-right visual field (LH-RVF). Subjects were explicitly directed to perform an analytic or holistic encoding process on both types of stimulus arrays. The serial array produced longer reaction times than the parallel array for both hemispheres. A RH-LVF reaction time advantage was found across both stimulus sets and instructions. In addition, an overall reaction time advantage was found for holistic instructions relative to analytic instructions, but this superiority was not effected by hemisphere or contextual stimuli.

“…One of them is the technique of brief tachistoscopic presentation of stimuli to the left(LVF) or right(RVF) visual fields, which has been extensively used over the past several years (Chiarello, Maxfield, Richards, & Kahan, 1995;Faust & Babcoff, 1997;Magaro & Moss, 1989;Ortells, Tudela, Noguera, & Abab, 1998;Vaid, 1983Vaid, , 1987Young & Ellis, 1985). This technique relies on the structure of the afferent pathways within the visual system, which ensures that the material presented to either the LVF or RVF is delivered to the contralateral hemisphere.…”
