论文摘要
新颖或意外的声音偏离相同声音的反复序列会导致行为分散注意力。最近的工作表明,在阅读期间,由于固定持续时间在单词的固定开始时出现了异常声音时,也会出现干扰。本研究检验了以下假设:固定持续时间的增加是由于saccadic抑制作用而发生的。这是通过操纵声音的时间发作相对于文本中单词的固定开始而完成的。如果新颖的声音会引起saccadic抑制作用,那么在扫视编程通常会发生时,在固定的后半部分出现时,它们应该会更加分散注意力。参与者阅读单句话,并在句子中固定五个目标单词时听到120毫秒的声音。在大多数情况下(p = 0.9),提出了相同的正弦波音(“标准”),而在其余的情况下(p = 0.1)提出了新的声音(“新颖”)。至关重要的是,在固定的上半场(0 ms延迟)或固定的下半部分(120毫秒延迟)播放声音。与Saccadic抑制假设一致,与0 ms延迟条件相比,新型声音在120毫秒内导致固定持续时间更长。但是,新颖的声音通常不会影响随后的扫视的执行。这些结果表明,意外的声音对扫视计划的影响很快,但没有扫视执行。
Novel or unexpected sounds that deviate from an otherwise repetitive sequence of the same sound cause behavioural distraction. Recent work has suggested that distraction also occurs during reading as fixation durations increased when a deviant sound was presented at the fixation onset of words. The present study tested the hypothesis that this increase in fixation durations occurs due to saccadic inhibition. This was done by manipulating the temporal onset of sounds relative to the fixation onset of words in the text. If novel sounds cause saccadic inhibition, they should be more distracting when presented during the second half of fixations when saccade programming usually takes place. Participants read single sentences and heard a 120 ms sound when they fixated five target words in the sentence. On most occasions (p= 0.9), the same sine wave tone was presented ("standard"), while on the remaining occasions (p= 0.1) a new sound was presented ("novel"). Critically, sounds were played either during the first half of the fixation (0 ms delay) or during the second half of the fixation (120 ms delay). Consistent with the saccadic inhibition hypothesis, novel sounds led to longer fixation durations in the 120 ms compared to the 0 ms delay condition. However, novel sounds did not generally influence the execution of the subsequent saccade. These results suggest that unexpected sounds have a rapid influence on saccade planning, but not saccade execution.
