Abstract

Detecting and learning structure in sounds is fundamental to human auditory perception. Evidence for auditory perceptual learning comes from previous studies where listeners were better at detecting repetitions of a short noise snippet embedded in longer, ongoing noise when the same snippet recurred across trials compared with when the snippet was novel in each trial. However, previous work has mainly used (a) temporally regular presentations of the repeating noise snippet and (b) highly predictable intertrial onset timings for the snippet sequences. As a result, it is unclear how these temporal features affect perceptual learning. In five online experiments, participants judged whether a repeating noise snippet was present, unaware that the snippet could be unique to that trial or used in multiple trials. In two experiments, temporal regularity was manipulated by jittering the timing of noise-snippet repetitions within a trial. In two subsequent experiments, temporal onset certainty was manipulated by varying the onset time of the entire snippet sequence across trials. We found that both temporal jittering and onset uncertainty reduced auditory perceptual learning. In addition, we observed that these reductions in perceptual learning were ameliorated when the same snippet occurred in both temporally manipulated and unmanipulated trials. Our study demonstrates the importance of temporal regularity and onset certainty for auditory perceptual learning. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

摘要

检测和学习声音中的结构是人类听觉感知的基础。听觉感知学习的证据来自先前的研究,当相同的短噪声片段在试验中重复出现时,与在每个试验中都是新的片段相比,听众在检测嵌入在更长持续噪声中的短噪声片段的重复时表现得更好。然而,先前的工作主要使用了 (a) 重复噪声片段的时间规则呈现和 (b) 片段序列的高度可预测的试验间起始时间。因此,尚不清楚这些时间特征如何影响感知学习。在五个在线实验中,参与者判断重复的噪声片段是否存在,而不知道该片段可能是该试验特有的,也可能在多个试验中使用。在两个实验中,通过在试验内抖动噪声片段的重复时间来操纵时间规则性。在随后的两个实验中,通过在试验间改变整个片段序列的起始时间来操纵时间起始确定性。我们发现,时间抖动和起始不确定性都降低了听觉感知学习。此外,我们观察到,当相同的片段出现在时间上受干扰和不受干扰的试验中时,感知学习的这些减少得到了缓解。我们的研究表明,时间规则性和起始确定性对于听觉感知学习很重要。(PsycInfo 数据库记录(c)2022 APA,保留所有权利)。
