A framework for dynamic assessment in phonology: stimulability revisited

Area of Science:

• Speech-Language Pathology
• Developmental Psychology
• Linguistics

Background:

• Phonological disorders affect children's speech sound acquisition.
• Assessing stimulability is crucial for treatment planning.
• Vygotsky's theory provides a foundation for dynamic assessment.

Purpose of the Study:

• To explore and evaluate the concept of stimulability in phonological disorders.
• To propose a dynamic assessment framework for evaluating children's learning potential.
• To identify factors influencing and facilitating speech sound development.

Main Methods:

• Utilizing Vygotsky's principles for a dynamic assessment framework.
• Identifying eight hierarchical antecedent cues to facilitate target sound learning.
• Systematically manipulating response complexity and clinician-provided consequent events.

Main Results:

• Stimulability can serve as a prognostic indicator for phonological disorders.
• The dynamic assessment framework aids in determining learning potential and influential factors.
• Identified cues and systematic manipulations can facilitate speech sound acquisition.

Conclusions:

• Stimulability is a valuable prognostic tool for children with phonological disorders.
• Dynamic assessment offers clinical utility in understanding a child's learning trajectory.
• A structured approach can effectively address key clinical questions in speech therapy.
