Abstract

Greater word length effects have been reported when a word was presented in the left visual field (LVF) than when presented in the right visual field (RVF). The current study employed 2 experiments to examine the visual-perceptual loci of asymmetric word length effect while testing the physical and linguistic length effects and the effect of visual angle increase at the RVF. Experiment 1 showed significant effects on the number of strokes in both VHFs (visual half fields) with the added significance of the number of syllables in the LVF, suggesting both parafoveal fields were affected by the physical length factors in contrast with the linguistic length factors, inducing asymmetric word length effects in the symmetrically presented word recognition in parafoveal vision. Experiment 2 widened the visual angle of the RVF presentation to test the differential effects of the visual-perceptual difficulty across the VHFs. It showed successful interruption at the RVF word recognition and comparable word length effects between the LVF and RVF. Therefore, this study suggests that the asymmetric word length effects in the parafoveal word recognition are attributable to the greater visual-perceptual difficulty at the LVF than at the RVF.

用韩语视觉词考察词长效应的半球偏侧性视知觉轨迹。
据报道,当一个单词在左视野(LVF)中呈现时,比在右视野(RVF)中呈现时,单词长度效应更大。本研究采用2个实验考察了非对称字长效应的视觉知觉位点,同时测试了物理和语言长度效应以及视觉角度增加对RVF的影响。实验1显示,随着LVF中音节数的增加,两个视觉半视野的笔画数都受到显著影响,这表明两个旁中央凹视野都受到物理长度因素的影响,而不是语言长度因素的影响,从而在对称呈现的旁中央凹视觉单词识别中产生不对称的单词长度效应。实验2拓宽了RVF呈现的视角,考察了视觉知觉困难在不同视点间的差异效应。它显示了裂谷热单词识别的成功中断,并且在LVF和RVF之间具有可比的单词长度效应。因此,本研究表明,旁中央凹单词识别中的不对称单词长度效应可归因于左心凹比右心凹更大的视觉知觉困难。

期刊介绍: Laterality: Asymmetries of Body, Brain and Cognition publishes high quality research on all aspects of lateralisation in humans and non-human species. Laterality"s principal interest is in the psychological, behavioural and neurological correlates of lateralisation. The editors will also consider accessible papers from any discipline which can illuminate the general problems of the evolution of biological and neural asymmetry, papers on the cultural, linguistic, artistic and social consequences of lateral asymmetry, and papers on its historical origins and development. The interests of workers in laterality are typically broad.
