In the present study, we provide compelling evidence that viewing objects automatically activates linguistic labels and that this activation is not due to task-specific memory demands. In two experiments, eye-movements of English speakers were tracked while they identified a visual target among an array of four images, including a phonological competitor (e.g., flower-flag). Experiment 1 manipulated the capacity to subvocally rehearse the target label by imposing linguistic, spatial, or no working memory load. Experiment 2 manipulated the need to encode target objects by presenting target images either before or concurrently with the search display. While the timing and magnitude of competitor activation varied across conditions, we observed consistent evidence of language activation regardless of the capacity or need to maintain object labels in memory. We propose that language activation is automatic and not contingent upon working memory capacity or demands, and conclude that objects' labels influence visual search.
在本研究中,我们提供了令人信服的证据,表明观看物体自动激活语言标签,而这种激活不是由于特定任务的记忆需求。在两项实验中,我们跟踪了英语使用者的眼动,让他们在一组四张图像中识别一个视觉目标,包括一个语音竞争对手(例如,花旗)。实验 1 通过施加语言、空间或无工作记忆负荷来操纵对目标标签进行内心默读的能力。实验 2 通过在呈现搜索显示之前或同时呈现目标图像来操纵对目标对象进行编码的需求。虽然竞争对象的激活时间和幅度因条件而异,但我们观察到无论记忆中保持对象标签的能力或需求如何,语言激活的一致证据。我们提出语言激活是自动的,不依赖于工作记忆容量或需求,并得出结论,对象的标签会影响视觉搜索。
