This study presents detailed case studies of children with protracted phonological development (speech sound disorders) across 16 languages. These individual profiles reveal cross-linguistic similarities and differences in phonological systems and intervention needs.
Area of Science:
- Linguistics
- Speech-Language Pathology
- Developmental Psychology
Background:
- Group studies offer broad insights into phonological development, but individual case studies provide in-depth analysis of phonological systems.
- Cross-linguistic comparisons of individual phonological profiles can reveal subtle similarities and differences not apparent in group data.
- Protracted phonological development (PPD), or speech sound disorders, requires detailed examination for effective intervention.
Purpose of the Study:
- To present detailed individual phonological profiles of children with PPD from 16 diverse languages.
- To analyze phonological systems, including word structure, segments, and features, within a constraints-based nonlinear framework.
- To explore implications for phonological theory, developmental models, and clinical intervention strategies.
Main Methods:
- Utilized a constraints-based nonlinear phonological framework to analyze individual case studies.
- Collected and described phonological profiles for children with PPD across 16 languages.
- Included intervention plans and, where available, follow-up data post-clinical intervention.
Main Results:
- Each profile details a child's phonological strengths and needs, focusing on word structure, segments, features, and their interactions.
- The study highlights both unique and shared patterns in phonological development and disorders across different linguistic backgrounds.
- Follow-up data provides insights into the effectiveness of suggested intervention plans.
Conclusions:
- Individual case studies are crucial for a comprehensive understanding of phonological systems in children with PPD.
- Cross-linguistic analysis of phonological profiles enriches theoretical frameworks and informs clinical practice.
- The findings have significant implications for the diagnosis and treatment of speech sound disorders globally.
