Participants' eye movements to four objects displayed on a computer screen were monitored as the participants clicked on the object named in a spoken instruction. The display contained pictures of the referent (e.g., a snake), a competitor that shared features with the visual representation associated with the referent's concept (e.g., a rope), and two distractor objects (e.g., a couch and an umbrella). As the first sounds of the referent's name were heard, the participants were more likely to fixate the visual competitor than to fixate either of the distractor objects. Moreover, this effect was not modulated by the visual similarity between the referent and competitor pictures, independently estimated in a visual similarity rating task. Because the name of the visual competitor did not overlap with the phonetic input, eye movements reflected word-object matching at the level of lexically activated perceptual features and not merely at the level of preactivated sound forms.
当参与者点击语音指令中提到的物体时,研究人员监测了他们对电脑屏幕上显示的四个物体的眼动情况。屏幕显示中包含所指对象的图片(例如一条蛇)、与所指对象概念相关的视觉表征具有共同特征的竞争对象(例如一根绳子),以及两个干扰对象(例如一张沙发和一把伞)。在所指对象名称的第一个音节被听到时,参与者更有可能注视视觉竞争对象,而不是两个干扰对象中的任何一个。此外,在一项视觉相似性评级任务中独立评估发现,这种效应不受所指对象和竞争对象图片之间视觉相似性的调节。由于视觉竞争对象的名称与语音输入不重叠,眼动反映了在词汇激活的感知特征层面上的词-物匹配,而不仅仅是在预激活的语音形式层面上。
