以前关于辅音词簇习得的研究表明，词尾词簇的习得往往先于词首词簇(Templin，1957；Lleó&Prince，1996；Levelt，Schiller&Levelt，2000)。本文通过对12名说英语的两岁儿童的图片识别任务，评估了这种不对称性可能的结构、形态、频率和发音方面的解释。结果表明，词尾+/S/词簇和鼻音+/z/词簇的产生比词首/S/+词尾簇和/S/+鼻音簇高得多。无论是结构性因素还是频率因素都无法解释这些发现。对2名1岁、1-2岁、6岁儿童的纵向自发生产数据的进一步分析，几乎不支持形态学在解释这些结果中所起的作用。我们认为，发音解释最好地解释了词首和词尾词簇产生的不对称性。
Previous work on the acquisition of consonant clusters points to a tendency for word-final clusters to be acquired before word-initial clusters (Templin, 1957; Lleó & Prinz, 1996; Levelt, Schiller & Levelt, 2000). This paper evaluates possible structural, morphological, frequency-based, and articulatory explanations for this asymmetry using a picture identification task with 12 English-speaking two-year-olds. The results show that word-final stop+/s/ clusters and nasal+/z/ clusters were produced much more accurately than word-initial /s/+stop clusters and /s/+nasal clusters. Neither structural nor frequency factors are able to account for these findings. Further analysis of longitudinal spontaneous production data from 2 children aged 1;1–2;6 provides little support for the role of morphology in explaining these results. We argue that an articulatory account best explains the asymmetries in the production of word-initial and word-final clusters.
