对左右利手者的视简单反应时及空间方向识别能力的实验研究

本研究应用单侧视野速示技术对左右利手被试不同视野的简单反应时及空间方向识别能力进行测试与分析。实验结果表明,左利组在两项实验中的左、中、右视野上的反应时均快于右利组,且左利组在左视野上的优势最为显著。经分析发现:左利者优势手在操作速度上的优势主要是因其大脑右半球具有较高的分析处理形象信息的能力所致;左利者右脑的这种功能优势与其大脑神经传导过程的特点有很大关系。本实验为研究和培养左利手运动员提供了一些神经心理学方面的依据和参考。

An Experimental Study on Left- and Right- Handers' Visual Simple Reaction Time and Ability of Spatial-Direction Discrimination

Visual simple reaction time and ability of spatial-direction discrimination of left-and right-handed students were measured and compared with visual half field tachisto test. Results showed that reaction times of the left, right, and middle visual fields in left-handed group were all shorter than those in right-handed group, with superiority specially in the left visual field in left-handed group. After analysis it is discovered that: 1. the main reason the left-handers are superior in operational speed of dominant hand may be that right hemispheres are more capable of analysing and processing image messages; 2. lefthanders' superior function of right hemisphere has closs relationship with the characteristics of their cerebral nerve conduction. This study has provided the training of left-handed players with neuro-psychological basis and reference.
