The Comparative Study Of Numerical Processing In Auditory And Visual Channel

Recently, the research of mathematical psychology continued to increase, especiallyin the field of numerical processing. Many aspects of this problem have been discussed bya lot of researchers, but the most studies of the numerical space representation are focusedon the subject if there is SNARC effect in visual channel so far. For the auditory channel,the number of the research is very small both here and abroad. Especially the SNARCeffect of the Chinese-character in visual channel and auditory channel, the research isfewer.In view of the above problem, there are two experiments which use SNACR classicresearch paradigm in the study. Numerical stimuli were presented in two different channels(visual and auditory channel).Participants are asked to react to the stimuli fast ancorrectly.Experiment1was carried on in auditory channel, participants should decide ifa numerical stimulus was greater than5or less than5by pressing the right or the leftresponse key. Experiment2were carried on in visual channel, the numerical stimulus werevisual number words rather than auditory number words, and the rest were the same withexperiment1. The two experiments were designed for discussing the SNARC effect invisual and auditory channel and then for comparison. The main conclusions of this studyare:(1) In experiment1, the SNARC effect of Chinese-character numbers in auditoryreached significance. That is mean, left hand had a fast reaction to small numbers whileright hand respond quickly to large numbers.(2) In experiment2, the SNARC effect of Chinese-character numbers in auditory isalso significant.(3) Comparing the two experiments, it suggests the pattern of SNARC effect inauditory an visual channel seems to be similar.But the RT of auditory number words islarger than visual number words, the accuracy is higher.
