Summary
This study examined speech sound disorders in young children, finding that their phonological systems follow strict rules similar to typical language development. These findings suggest speech sound delays, not unique deviations, guiding assessment and treatment strategies.
Area of Science:
- Linguistics
- Speech-Language Pathology
- Developmental Psychology
Background:
- Functional speech sound disorders affect phonological system development.
- Understanding these systems is crucial for effective intervention.
Purpose of the Study:
- To analyze the phonetic inventories and phonotactic constraints in children with functional speech sound disorders.
- To characterize the typological nature of these disordered phonological systems.
- To compare disordered systems with principles of normal first language acquisition.
Main Methods:
- Examined phonological systems of 40 children (40-80 months) with functional misarticulations.
- Analyzed phonetic inventories and phonotactic constraints.
- Identified governing principles and implicational laws.
Main Results:
- Disordered phonological systems exhibit severe constraints.
- These constraints allow for typological characterization and implicational laws.
- Principles governing disordered systems closely parallel normal first language acquisition.
Conclusions:
- Properties of functional speech sound disorders represent delays, not deviations, in normal acquisition.
- Assessment and treatment can leverage principles of normal phonological development.
- Learning patterns in disordered systems align with typical developmental trajectories.
