A crucial question in cognitive science is how linguistic and visual information are integrated. Previous research has shown that eye movements to objects in the visual environment are locked to linguistic input. More surprisingly, listeners fixate on now-empty regions that had previously been occupied by relevant objects. This 'looking at nothing' phenomenon has been linked to the claim that the visual system constructs sparse representations of the external world and relies on saccades and fixations to extract information in a just-in-time manner. Our model provides a different explanation: based on recent work in visual cognition and memory, it assumes that the visual system creates and stores detailed internal memory representations, and that looking at nothing facilitates retrieval of those representations.
认知科学中的一个关键问题是语言信息与视觉信息如何整合。先前的研究表明,视觉环境中对物体的眼动与语言输入相关联。更令人惊讶的是,听者会注视先前被相关物体占据、现在已空无一物的区域。这种“注视虚无”现象与视觉系统构建外部世界的稀疏表征并依靠扫视和注视即时提取信息的观点有关。我们的模型给出了不同的解释:基于视觉认知与记忆方面的最新研究,它假定视觉系统创建并存储详细的内部记忆表征,而注视虚无有助于这些表征的提取。
