当一个口语单词展开时，视觉注意力可以立即指向概念上相关但不相关的物体，即使它们在其他维度上不匹配，这些维度通常会决定场景中的哪些物体是展开单词的适当指涉物（Huettig & Altmann，2005）。在这里，我们表明，语言和并发的视觉对象之间的映射也可以介导的视觉形状的关系。在听到“蛇”，参与者直接公开的注意力立即，在一个视觉显示描绘四个对象，一张图片的电缆，虽然参与者已经看到了约5秒的视觉显示与四个对象之前，听到的目标词足够的时间来认识到他们是什么对象。花在固定电缆上的时间与一般蛇和这种特殊电缆之间的视觉相似性的评级显着相关。重要的是，由于句子的上下文偏向于蛇的概念，参与者在“蛇”出现之前就看了蛇，但他们直到听到“蛇”才看视觉上相似的电缆。最后，我们证明，这种激活，在某些情况下（e。例如，在一个实施例中，在处理同音异义词的主导意义时），限制视觉注意力的方向，即使它在上下文中明显不合适。我们的结论是，语言介导的注意力可以引导口语和视觉对象之间的视觉匹配，但这样的匹配是基于词汇输入，可能不会被调制的上下文适当性。
Visual attention can be directed immediately, as a spoken word unfolds, towards conceptually related but nonassociated objects, even if they mismatch on other dimensions that would normally determine which objects in the scene were appropriate referents for the unfolding word (Huettig & Altmann, 2005). Here we demonstrate that the mapping between language and concurrent visual objects can also be mediated by visual-shape relations. On hearing "snake", participants directed overt attention immediately, within a visual display depicting four objects, to a picture of an electric cable, although participants had viewed the visual display with four objects for approximately 5 s before hearing the target word-sufficient time to recognize the objects for what they were. The time spent fixating the cable correlated significantly with ratings of the visual similarity between snakes in general and this particular cable. Importantly, with sentences contextually biased towards the concept snake, participants looked at the snake well before the onset of "snake'', but they did not look at the visually similar cable until hearing "snake''. Finally, we demonstrate that such activation can, under certain circumstances (e. g., during the processing of dominant meanings of homonyms), constrain the direction of visual attention even when it is clearly contextually inappropriate. We conclude that language-mediated attention can be guided by a visual match between spoken words and visual objects, but that such a match is based on lexical input and may not be modulated by contextual appropriateness.
