在3个实验中考察了视觉言语知觉的偏侧化。参与者被呈现一张逼真的计算机动画脸，在没有声音的情况下表达4个辅音-元音音节中的1个。脸出现在视野中的5个位置中的1个。参与者的任务是识别每个测试音节。为了防止在面部呈现过程中的眼球运动，参与者必须在阅读语音的同时进行固定任务。在一项研究中，发现了偏心效应，沿着有一个小但显著的差异，有利于右视野（左半球）。同样的结果也出现在非语言性的嘴部运动（如接吻）中。这些结果表明，左半球的优势是基于动态视觉信息的处理，而不是从面部运动的语言意义的提取。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
The lateralization of visual speech perception was examined in 3 experiments. Participants were presented with a realistic computer-animated face articulating 1 of 4 consonant-vowel syllables without sound. The face appeared at 1 of 5 locations in the visual field. The participants' task was to identify each test syllable. To prevent eye movement during the presentation of the face, participants had to carry out a fixation task simultaneously with the speechreading task. In one study, an eccentricity effect was found along with a small but significant difference in favor of the right visual field (left hemisphere). The same results were found with the face articulating nonlinguistic mouth movements (eg, kiss). These results suggest that the left-hemisphere advantage is based on the processing of dynamic visual information rather than on the extraction of linguistic significance from facial movements.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
