词汇加工中视觉干扰效应及影响因素

Visual Interference Effect During Word Processing and Its Influential Factors

采用词汇判断任务,以中文词语、面孔图片和韩文非词为实验材料,通过三个实验考察了词汇加工中视觉干扰效应及影响因素。结果发现:(1)视野内的干扰材料会减慢目标词汇加工的速度;(2)词汇加工的干扰效应受到干扰材料和目标材料类别一致性的调节,同类别材料会引起更强的干扰效应。结果说明,词汇加工中视觉干扰效应可能反映了同类别的干扰刺激和目标刺激在类别特异性加工脑区内的资源竞争。

This study conducted three experiments,in which Chinese words,facial images,and Korean nonwords were used as materials.By using a lexical decision task,this study aimed to explore the visual interference effect during word processing and its influential factors.The results showed that:1)The interference materials in the visual field slowed down the reading speed of target word processing.2)The visual interference effect was regulated by the category consistency between the interference materials and the target materials,in which the materials belonging to the same category produced a stronger interference effect.These results suggest that the visual interference effect during word processing might be accounted by the potential competition for neural resources in the category-specific brain area.
