A Format for Identifying Interactions Among Measures of Communication Skills

Abstract

A format for longitudinally tracking interactions among measures representing different domains of communication was developed in response to calls for integrative approaches to language assessment. This longitudinal case study examined measures of segmental phonology, nonsegmental phonology, and syntax/morphology in a child with language impairment in order to illustrate the effectiveness of this format in identifying interactions. The format detected trade-offs and co-occurrences, which changed during the 6 1/2 yearsof study. The results support Crystal’s (1987) "bucket" theory of language and the value of integrative approaches to assessment.
