PURPOSE
The purpose of this study was to assess intratest scatter (variability) on standardized tests of expressive language by preschool-age children who do (CWS) and do not stutter (CWNS).
METHOD
Participants were 40 preschool-age CWS and 46 CWNS. Between-group comparisons of intratest scatter were made based on participant responses to the Expressive subtest of the (TELD-Exp; Hresko, Reid, & Hamill, 1999) and the (EVT-2; Williams, 2007). Within-group correlational analyses between intratest scatter and stuttering frequency and severity were also conducted for CWS.
RESULTS
Findings indicated that, for CWS, categorical scatter on the EVT-2 was positively correlated with their stuttering frequency. No significant between-group differences in intratest scatter were found on the TELD-Exp or the EVT-2.
CONCLUSIONS
Consistent with earlier findings, variability in speech-language performance appears to be related to CWS' stuttering, a finding taken to suggest an underlying cognitive-linguistic variable (e.g., cognitive load) may be common to both variables.
目的
本研究旨在评估患有口吃（CWS）和未患口吃（CWNS）的学龄前儿童在表达性语言标准化测试中的测试内散点（变异性）。
方法
参与者包括40名学龄前CWS儿童和46名CWNS儿童。基于参与者对《皮博迪图片词汇测验-表达性》（TELD-Exp；赫雷斯科、里德和哈米尔，1999年）以及《表达性词汇测验第二版》（EVT-2；威廉姆斯，2007年）表达性子测验的回答，进行了组间测试内散点比较。还对CWS儿童进行了测试内散点与口吃频率和严重程度之间的组内相关性分析。
结果
研究结果表明，对于CWS儿童，EVT-2上的类别散点与他们的口吃频率呈正相关。在TELD-Exp或EVT-2上未发现组间测试内散点的显著差异。
结论
与早期研究结果一致，言语语言表现的变异性似乎与CWS儿童的口吃有关，这一发现表明潜在的认知语言变量（如认知负荷）可能是这两个变量共有的。
