Hemispheric Interference in Manual Verbal Tasks Psychology Essay
The most common paradigm for studying motor cognitive interference is the simultaneous execution of hand movements and verbal commands Simon and Sussman, 1987 Hiscock et al. 1989 Serrien, 2009. If interference effects in dual tasks are strictly due to manual dominance, symmetric decreases in tapping performance on concurrent tasks should occur for the dominant hand regardless of whether or not they correspond to: Barbara Cherry, Department of Psychology, University of Southern California, Los Angeles, Saul Mcleod, PhD. The left brain is associated with logic, analytical thinking and language processing, while the right brain is associated with creativity, intuition and holistic thinking. However, this is an oversimplification, as both hemispheres of the brain work together in most activities. Hemispheric lateralization is the idea that both hemispheres exist. This article presents a systematic review of the empirical literature using dual-task interference methods to investigate the online involvement of language in various cognitive tasks. In these studies, participants perform a primary task X, presumably recruiting linguistic resources, while also engaging in a secondary, concurrent task. Here, a dual-task approach was adopted for evaluating changes in neural activity associated with a motor command. To this end, participants performed a self-paced motor tapping task in a unimanual and bimanual context, together with a verbal counting task. Neural dynamics were assessed by EEG coherence in the. However, relatively little is known about the possible asymmetries in the hemispheric differences, perhaps because of the generally small hemispheric asymmetries in ERP amplitude observed, for example by Brown et al. 1985 Molfese et al. 1975 Neville, 1980, which may arise from an inadequate number or placement of electrodes. The current research suggests that two different forms of functional lateralization support individual differences in visuospatial and verbal divergent thinking. These findings have important implications for our understanding of hemispheric interaction mechanisms of creative thinking. 1 Introduction. Nearly zero differences were found for mathematical and verbal skills, both psychological domains for which strong gender differences have been proposed and reported in separate studies. Substantial performance differences have been identified only for the mental rotation D objects, with men and boys performing better than women. One of the most popular experimental paradigms for functional neuroimaging studies of working memory is the n-back task, in which subjects are asked to monitor the identity or location of a series of verbal or nonverbal stimuli and to indicate when the currently presented stimulus is received. the same as the one who presented n trials.
