A Format for Identifying Interactions Among Measures of Communication Skills: A Case Study

Area of Science:

• Speech and Language Pathology
• Developmental Linguistics
• Child Language Acquisition

Background:

• Existing language assessments often lack integrative approaches to track developmental changes.
• There is a need for methods to longitudinally analyze interactions across different linguistic domains.
• Crystal's (1987) 'bucket' theory suggests interconnectedness in language development.

Purpose of the Study:

• To present a novel format for longitudinally tracking interactions among communication measures.
• To examine the effectiveness of this format in a case study of a child with language impairment.
• To illustrate how the format identifies dynamic relationships between phonology and syntax/morphology.

Main Methods:

• A longitudinal case study design was employed.
• Measures of segmental phonology, nonsegmental phonology, and syntax/morphology were tracked over 6.5 years.
• A new format was used to analyze interactions, trade-offs, and co-occurrences among these measures.

Main Results:

• The developed format successfully identified dynamic trade-offs and co-occurrences between linguistic domains.
• These interactions showed changes throughout the 6.5-year observation period.
• The findings demonstrate the utility of the format in capturing complex developmental patterns.

Conclusions:

• The proposed format is effective for integrative, longitudinal language assessment.
• Results support the interconnectedness of language components as suggested by Crystal's 'bucket' theory.
• This approach enhances understanding of language impairment development and intervention.
