To examine the role of inter-word spaces during reading, we used a gaze-contingent boundary paradigm to manipulate parafoveal preview (i.e., valid vs. invalid preview) in a normal text condition that contained spaces (e.g., "John decided to sell the table") and in an unsegmented text condition that contained random numbers instead of spaces (e.g.,"John4decided8to5sell9the7table"). Preview effects on mean first-fixation durations were larger for normal than unsegmented text conditions, and survival analyses revealed a delay in the onset of both preview validity and word-frequency effects on first-fixation durations for unsegmented relative to normal text. Taken together with simulations that were conducted using the E-Z Reader model, the present findings indicated that unsegmented text deficits reflect disruptions to both parafoveal processing and lexical processing. We discuss the implications of our results for models of eye-movement control.
为了研究阅读过程中单词间距的作用，我们使用了注视点连续边界范式，在包含空格的正常文本条件下（例如，“John decided to sell the table”）和包含随机数字而非空格的无分割文本条件下（例如，“John4decided8to5sell9the7table”）操纵副中央凹预视（即有效预视与无效预视）。正常文本条件下，预视对首次注视平均持续时间的影响大于无分割文本条件，生存分析表明，相对于正常文本，无分割文本在预视有效性和词频对首次注视持续时间的影响出现上存在延迟。结合使用E-Z Reader模型进行的模拟，目前的研究结果表明，无分割文本缺陷反映了副中央凹加工和词汇加工的中断。我们讨论了研究结果对眼动控制模型的意义。
