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.

摘要

与在右视野 (RVF) 中呈现的单词相比，在左视野 (LVF) 中呈现单词时，已报告了更大的单词长度效应。目前的研究采用 2 个实验来检查不对称字长效应的视觉感知位点，同时测试 RVF 的物理和语言长度效应以及视角增加的影响。实验 1 显示对两个 VHF（视觉半场）中的笔划数有显着影响，并且 LVF 中的音节数具有额外的重要性，这表明与语言长度因素相比，两个副中央凹场都受到物理长度因素的影响，在旁中心视觉中对称呈现的单词识别中诱导不对称单词长度效应。实验 2 扩大了 RVF 演示的视角，以测试 VHF 视觉感知困难的差异效应。它显示成功中断 RVF 单词识别和 LVF 和 RVF 之间可比较的单词长度效果。因此，这项研究表明，副中央凹单词识别中的不对称单词长度效应可归因于 LVF 比 RVF 更大的视觉感知困难。
