The purpose of this capstone is to determine if certain items from the CDI: WS could be used to assess the productivity of tense marking in young children at risk for specific language impairment at 36 months. Recently, Hadley and Short (2005) devised cumulative measures of capturing the onset of tense marking during the earliest period of grammatical development. Their investigation was driven by the need to determine if the late emergence and limited productivity of tense morphemes could be used to detect children at risk for SLI at younger ages. However, their methods, which rely upon comprehensive, longitudinal language samples, are not likely to be adopted by practitioners. As such, it is important to determine if similar results can be obtained using a parent report approach for documenting the emergence tense morphemes. The overall objective of this study will be to determine if a parent report approach to assessment will produce similar results. If less costly approaches can be devised and shown to be valid, this will have enormous utility for practicing speech-language clinicians. The literature review is organized in the following fashion. The first section will address the validity and utility of parent report as a method of early identification. The following section will address the early identification of children at-risk for SLI, framed within a clinical marker approach. Finally, the results of previous parent report studies will be reviewed in detail providing the rationale for the current study and the methods used (Dale, 1991; Thal et al., 1999; Bryant, 2003; Heilman et al., 2005).
