Comparison of cross-language generalisation following speech therapy
Summary
Understanding bilingual phonological development is crucial for identifying speech disorders in young children. Intervention strategies depend on how speech sound errors generalize across languages.
Area of Science:
- Speech-Language Pathology
- Developmental Psychology
- Linguistics
Background:
- Limited normative data exists for sequential bilingual phonological development in preschoolers.
- Accurate assessment of speech disorders in bilingual children is challenging.
- Determining the need for intervention in one or both languages is complex.
Observation:
- This study reports treatment efficacy for two bilingual children with speech disorders.
- Phonological development in sequentially bilingual children varies.
- Cross-language generalization patterns differ based on underlying speech processing deficits.
Findings:
- Different patterns of cross-language generalization were observed in the treated children.
- The underlying deficit in speech processing influences how phonological errors transfer between languages.
- Intervention outcomes suggest tailored approaches are necessary.
Implications:
- Normative data for sequential bilingual phonological development is needed for accurate diagnosis.
- Intervention decisions should consider potential cross-language generalization.
- Understanding speech processing deficits can guide targeted bilingual speech therapy.
