语言受到音位限制--对音序的限制。一种内隐学习范式考察了参与者是否能够通过接触一组音节在两个表征水平上获得限制。受试者被暴露于类别音段水平的限制(例如，/f/仅在起始处，/S/仅在尾部)以及梯度特征水平的限制(例如，唇部摩擦音/v/和IFF出现在起始点的时间为75%，尾部为25%)。言语错误显示，参与者在两个表征水平上都编码了约束。通过将错误偏向单音节位置，音段限制强化了错误保持目标音节位置的倾向(例如，几乎没有/S/错误发生在声母上)。相反，由于特征限制允许两个音节位置都出现错误，对其进行编码削弱了保留目标音节位置的倾向(例如，受特征和音段限制的影响，/f/错误出现在尾声中的频率比/S/错误在声头出现的频率更高)。最后，在第二项研究中，参与者未能学习到背部停止辅音的特征限制。讨论了这些结果对特征表示和处理的影响。(C)2004 Elsevier Inc.保留所有权利。
Languages are subject to phonotactic constraints-restrictions on sound sequences. An implicit learning paradigm examined whether participants could acquire constraints at two levels of representation through exposure to a set of syllables. Participants were exposed to categorical segment-level constraints (e.g., /f/ only in onset, /s/ only in coda) as well as gradient featural-level constraints (e.g., labiodental fricatives /v/ and Iff occurred in onset position 75% of the time, coda 25%). Speech errors revealed that participants encoded constraints at both levels of representation. By biasing errors towards a single syllable position, segmental constraints strengthened the tendency of errors to preserve target syllable position (e.g., virtually no /s/ errors occurred in onset). In contrast, since the featural constraint allowed errors to occur in both syllable positions, encoding it weakened the tendency to preserve target syllable position (e.g., /f/ errors, influenced by featural as well as segmental constraints, surfaced in coda more often than /s/ errors surfaced in onset). Finally, participants in a second study failed to learn featural constraints for dorsal stop consonants. The implications of these results for the representation and processing of features are discussed. (C) 2004 Elsevier Inc. All rights reserved.
