Relationship Between Attention and Accuracy During Dynamic Temporal and Tactile Cueing Treatment for Childhood Apraxia of Speech
Jessica Katz, Maria I. Grigos, Julie CasePurpose:
This study explored the relationship between attention and speech accuracy over the course of Dynamic Temporal and Tactile Cueing (DTTC) treatment with varied practice partners. DTTC is a motor-based intervention that emphasizes conscious practice. The relationship between attention and motor learning has not been explored in the context of DTTC. In addition, it is unknown whether attention and performance differ with varied practice partners, such as caregivers who often engage in home practice with their children.
Method:
Eight children with childhood apraxia of speech (2;6–7;11 [years;months]) received 8 weeks of DTTC. Half of the children engaged in practice with just a clinician, and the other half engaged in practice with both a clinician and caregiver. Attention was measured through time-on-task (TOT) and the number of treatment target productions (productivity). Speech accuracy was measured to examine the relationship of attention with speech performance. Correlation analyses measured the relationship between attention and accuracy. A one-way analysis of variance analyzed differences in attention during sessions with only a clinician as compared to a clinician and caregiver.
Results:
Analyses revealed a positive relationship between productivity and speech accuracy, specifically for children who only practiced with their clinician. In addition, greater productivity and TOT were observed for children who only practiced with a clinician, as compared to both a clinician and caregiver.
Conclusions:
The relationship between productivity and speech accuracy supports the value of high-intensity practice for speech motor learning. Group differences in attention are attributed to the structure of sessions when treatment is solely administered by a clinician, as compared to sessions that redirect practice time to involve caregivers. Clinical implications for caregiver involvement are addressed.
