大多数研究长期记忆对非词重复（NWR）的影响集中在词汇水平变量上。音位层面的变量很少受到关注，虽然有理由期待显着的亚词汇效应在NWR。为了进一步了解NWR的基本过程，本研究通过测试当刺激物中含有在言语发展过程中较晚获得的辅音和较早获得的辅音时，是否表现出不同，来检验亚词汇长期语音知识的影响。（实验1）和20（实验2）大学生完成的任务，调查是否实验音素水平变量（辅音习得年龄）同样影响NWR和词汇通达任务，这些任务旨在改变发音，语音感知和语音短期记忆需求。词汇访问任务进行了沉默或并发的清晰度，以探讨是否辅音年龄的收购效果出现之前或之后的发音planning.ResultsNWR准确性下降的项目，包括后来与早期收购的音素。类似的辅音年龄的收购效果观察到的准确性措施的非字阅读和词汇的决定进行在沉默或并发articulation.ConclusionResults表明，NWR性能是敏感的音素级的语音知识在长期记忆。因此，NWR不应被视为单纯语音短期记忆损伤的诊断工具。补充材料shttps：doi.org/10.23641/asha.5435137
PurposeMost research examining long-term-memory effects on nonword repetition (NWR) has focused on lexical-level variables. Phoneme-level variables have received little attention, although there are reasons to expect significant sublexical effects in NWR. To further understand the underlying processes of NWR, this study examined effects of sublexical long-term phonological knowledge by testing whether performance differs when the stimuli comprise consonants acquired later versus earlier in speech development.MethodThirty (Experiment 1) and 20 (Experiment 2) college students completed tasks that investigated whether an experimental phoneme-level variable (consonant age of acquisition) similarly affects NWR and lexical-access tasks designed to vary in articulatory, auditory-perceptual, and phonological short-term-memory demands. The lexical-access tasks were performed in silence or with concurrent articulation to explore whether consonant age-of-acquisition effects arise before or after articulatory planning.ResultsNWR accuracy decreased on items comprising later- versus earlier-acquired phonemes. Similar consonant age-of-acquisition effects were observed in accuracy measures of nonword reading and lexical decision performed in silence or with concurrent articulation.ConclusionResults indicate that NWR performance is sensitive to phoneme-level phonological knowledge in long-term memory. NWR, accordingly, should not be regarded as a diagnostic tool for pure impairment of phonological short-term memory.Supplemental Materialshttps://doi.org/10.23641/asha.5435137
