以往的词汇再认掩蔽启动研究表明，重复启动受实验信息结构的影响，如目标重复的比例。使用自然主义任务和眼动追踪的研究表明，人们使用语言知识来预测即将到来的单词。我们研究了实验中目标重复的比例是否对预期眼动有类似的影响。我们使用了单词到图片匹配任务（即，视觉世界范例），并仔细控制目标重复比例。参与者的眼球运动从图片出现时开始跟踪，在目标词出现前一秒。当目标重复比例高时，在此预览期内，重复目标的注视多于其他项目，而当目标重复比例低时，在此预览期内，重复目标的注视少于其他项目。这些结果表明，语言预期可以由短时实验内试验结构驱动，并对启动效应的泛化、预期眼动的基础和实验设计等方面具有启示意义。
Previous masked priming research in word recognition has demonstrated that repetition priming is influenced by experiment-wise information structure, such as proportion of target repetition. Research using naturalistic tasks and eye-tracking has shown that people use linguistic knowledge to anticipate upcoming words. We examined whether the proportion of target repetition within an experiment can have a similar effect on anticipatory eye movements. We used a word-to-picture matching task (i.e., the visual world paradigm) with target repetition proportion carefully controlled. Participants’ eye movements were tracked starting when the pictures appeared, one second prior to the onset of the target word. Targets repeated from the previous trial were fixated more than other items during this preview period when target repetition proportion was high and less than other items when target repetition proportion was low. These results indicate that linguistic anticipation can be driven by short-term within-experiment trial structure, with implications for the generalization of priming effects, the bases of anticipatory eye movements, and experiment design.
