为了研究刺激结构和可变性对感知学习的影响，我们比较了训练前后的转录准确率与规则产生的合成语音。受试者接受了单独的单词或合成语音的流畅句子的训练，这些句子要么是新颖的刺激，要么是重复的固定刺激列表。每天接受相同刺激训练的受试者的改善程度与接受新刺激的受试者一样。在第二个实验中，减少了重复刺激集的大小。在这些条件下，重复刺激训练的受试者没有概括到新的刺激，以及与新的刺激训练的受试者。我们的研究结果表明，知觉学习取决于在何种程度上的训练刺激表征的基本结构的完整的刺激集。此外，我们发现，孤立词的训练只增加了孤立词的可理解性，尽管句子的训练增加了孤立词和句子的可理解性。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
To examine the effects of stimulus structure and variability on perceptual learning, we compared transcription accuracy before and after training with synthetic speech produced by rule. Subjects were trained with either isolated words or fluent sentences of synthetic speech that were either novel stimuli or a fixed list of stimuli that was repeated. Subjects who were trained on the same stimuli every day improved as much as did the subjects who were given novel stimuli. In a second experiment, the size of the repeated stimulus set was reduced. Under these conditions, subjects trained with repeated stimuli did not generalize to novel stimuli as well as did subjects trained with novel stimuli. Our results suggest that perceptual learning depends on the degree to which the training stimuli characterize the underlying structure of the full stimulus set. Furthermore, we found that training with isolated words only increased the intelligibility of isolated words, although training with sentences increased the intelligibility of both isolated words and sentences.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
