虽然语音类别是由多个声学维度定义的，但有些语音类别的感知权重比其他语音类别的感知权重大，并且在非母语语音感知中存在母语权重的残余影响。最近对非语言声音类别学习的研究表明，经验声音的分布特征会影响感知线索权重：在一个维度上增加可变性会导致听者在随后的类别学习中较少依赖它（Holt & Lotto，2006）。本实验探讨了这一现象对日本人学习英语/r/-/l/范畴的影响。训练是使用视频游戏范例来完成的，该范例强调声音类别、视觉信息和玩家对视频游戏角色的反应之间的关联，而不是公开的分类或明确的反馈。在5天内玩2.5小时游戏的受试者在/r/-/l/感知方面表现出与先前研究中2-4周的明确分类训练相当的改善，并表现出向更像本地人的感知线索权重的转变。
Although speech categories are defined by multiple acoustic dimensions, some are perceptually weighted more than others and there are residual effects of native-language weightings in non-native speech perception. Recent research on nonlinguistic sound category learning suggests that the distribution characteristics of experienced sounds influence perceptual cue weights: Increasing variability across a dimension leads listeners to rely upon it less in subsequent category learning (Holt & Lotto, 2006). The present experiment investigated the implications of this among native Japanese learning English /r/-/l/ categories. Training was accomplished using a videogame paradigm that emphasizes associations among sound categories, visual information, and players' responses to videogame characters rather than overt categorization or explicit feedback. Subjects who played the game for 2.5 h across 5 days exhibited improvements in /r/-/l/ perception on par with 2-4 weeks of explicit categorization training in previous research and exhibited a shift toward more native-like perceptual cue weights.
