ETS Praxis Speech-Language Pathology (5331) Form 3 Practice Test

The chosen statement highlights the significance of stimulability in understanding a child's ability to produce specific sounds, particularly in the context of gliding, where /r/ sounds may be substituted with /w/ or /j/. Stimulability refers to a child's ability to produce a sound accurately when given cues or models by a speech-language pathologist (SLP). In this case, a child who is not stimulable for the /r/ sound suggests that they cannot produce this sound correctly even with assistance, indicating that there may be underlying difficulties in articulation or phonological processes.

This lack of stimulability is crucial for prognosis because it often indicates that the child may require targeted speech therapy to develop the ability to produce consonant sounds like /r/. When a child is not stimulable, it may reflect more entrenched speech errors, suggesting that without specialized intervention, the child is unlikely to spontaneously develop the correct production of /r/ over time.

In relation to other options, the notion that sounds could develop without treatment in the absence of stimulability does not align with typical speech development patterns observed in children with speech sound disorders. Similarly, the premise that stimulability can predict the rate of improvement for different sounds like /l/ and /r/ fails
