stimulability
A diagnostic technique measuring a client's ability to produce target sounds with various types and levels of clinician support.
Full Definition
Stimulability refers to a client's responsiveness to stimulation or cueing when attempting to produce speech sounds they typically produce in error. During stimulability testing, the speech-language pathologist provides various levels of support including auditory models, visual cues, tactile prompts, and phonetic placement instruction to determine if the client can achieve more accurate productions. High stimulability often indicates a favorable prognosis for treatment, as it suggests the client has the motor capability to produce the target sound. Stimulability results guide treatment planning, goal prioritization, and intervention approach selection in articulation and phonological therapy.
Usage
Usage note: Key prognostic indicator for articulation therapy success. Test at various linguistic levels (isolation, syllable, word).
