在一系列重复的声音（标准）中意外出现一个奇怪的听觉刺激（新奇），会对参与者在不相关的视觉任务中的表现产生负面影响。本研究试图验证Parmentier（2008）的听觉新奇性分心模型中出现的新预测。受试者将视觉箭头的方向归类为与任务无关的声音。两个时间间隔之间的干扰和目标进行了测试，在单独的试验块。罕见的听觉小说由“左”或“右”组成，这与即将到来的目标一致或不一致。这些数据证实了在面对一个新的（新奇的分心），以及在不一致的试验，由于干扰和目标（语义效应）之间的串扰干扰的进一步延迟的反应放缓。更重要的是，与我们的预测一致，结果进一步表明：（1）语义效应，而不是新奇的分心，随着分心物和目标之间的时间间隔而增加;（2）如果反应需要激活最近被抑制的网络（后新奇语义效应），那么在新试验后的第一次标准试验中产生的反应就会减慢。总的来说，这些数据支持这样一种观点，即听觉新奇性的行为分心反映了一个贡献者的马赛克，其影响可以在试验中产生涟漪。
The unexpected occurrence of an oddball auditory stimulus (novel) among an otherwise repeated stream of sounds (standards) is known to impact negatively on participants' performance in an unrelated visual task. The present study sought to test new predictions emerging from Parmentier's (2008) model of distraction by auditory novelty. Participants categorized the direction of visual arrows preceded by a task-irrelevant sound. Two time intervals between distractor and target were tested in separate blocks of trials. Rare auditory novels consisted of the words "left" or "right", which were either congruent or incongruent with the upcoming target. The data confirmed the slowing of response in the face of a novel (novelty distraction) as well as, on incongruent trials, a further delay due to cross-talk interference between distractor and target (semantic effect). More importantly, and in line with our predictions, the results further showed that (1) the semantic effect, but not novelty distraction, increased with the time interval between distractor and target; and that (2) the production of a response on the first standard trial following a novel trial was slowed if that response required the activation of a recently inhibited network (post-novelty semantic effect). Overall, the data lend support to the view that behavioral distraction by auditory novelty reflects a mosaic of contributors, the effects of which can ripple across trials.
