The purpose of this study was to describe the process of /s/ acquisition among young children who substituted an interdental fricative for /s/. The Deep Test of Articulation for /s/ was administered once a month during seven consecutive months to 11 kindergarten children who misarticulated /s/. Results indicate that acquisition of /s/ was not influenced by its function as a syllable-releasing or syllable-arresting consonant. One factor associated with /s/ acquisition was the presence of adjacent palatal-fricative/affricate sounds. Although there was considerable variability among subjects in rate of /s/ acquisition, when a score of 38% correct /s/ productions or better during two consecutive testing periods on The Deep Test of Articulation was obtained, four out of five subjects continued to produce high rates of correct /s/ responses. Implications of these data are discussed.
本研究的目的是描述那些用齿间擦音替代/s/的幼儿习得/s/的过程。对11名/s/发音错误的幼儿园儿童连续七个月每月进行一次/s/发音深度测试。结果表明，/s/的习得不受其作为音节释放或音节阻碍辅音功能的影响。与/s/习得相关的一个因素是相邻腭擦音/塞擦音的存在。尽管受试者在/s/习得速度上存在很大差异，但当在发音深度测试中连续两个测试期获得38%或更高的/s/正确发音分数时，五分之四的受试者继续保持较高的/s/正确反应率。文中讨论了这些数据的意义。
