- NCT04858035
- Lead Sponsor
- Montclair State University
- Brief Summary
The objective of this study is to measure the effects of online perceptual training on perception and production in children with RSE who exhibit atypical perception relative to norms from our lab-based pilot data. In a multiple-baseline across-subjects design, 10 children with RSE will begin in a baseline phase probing perceptual acuity for /r/. Perceptual training with multiple types of stimuli will be initiated in a staggered fashion. Production probes elicited before and after treatment will assess the extent to which perception gains transfer to /r/ production.
- Detailed Description
Following the initial evaluation to determine eligibility, participants will be enrolled in a baseline phase in which perception and production abilities will be probed but not treated. In a multiple-baseline across-subjects design with randomization, the 10 participants will be randomly assigned to transition from the baseline to the treatment condition at one of 7 possible points, ranging from 4 to 10 baseline sessions. After baseline sessions, perceptual training will be delivered in twelve 30-minute sessions occurring 3 times per week for 4 weeks. The training is fully computerized and can be self-administered, but a study clinician will attend one session per participant per week to ensure attention to study tasks. Each session will feature three listening tasks of approximately equal duration. Following perceptual training, participants will receive 4 60-minute sessions of production training completed over two weeks.

Group Intervention Description Online Speech Training Production training Participants will be randomly assigned to transition from the baseline to the treatment condition at one of 7 possible points, ranging from 4 to 10 baseline sessions. All participants will receive 12 sessions of perceptual training over 4 weeks. Finally, participants will complete a 3-session maintenance phase in which perception and production are probed but not treated. Perception will be measured using the identification and category goodness judgment. Following completion of perception training all participants will complete two weeks of production training. The production training will consists of 4, 60-minute sessions. Each session will provide instruction and practice trials.

- Primary Outcome Measures
Name Time Method Change in percent accuracy pooled across perception tasks Pre- and within-treatment (up to one month); pre and 1 week post-treatment Treatment tasks 2 (identification) and 3 (category goodness judgment) are identical to the tasks used to assess performance in the baseline phase, with the single exception that accuracy feedback is provided during the treatment phase.
Participants' progress will be tracked continuously across baseline and treatment phases using percent accuracy on these two tasks. In Task 2, accuracy in classifying stimuli as /r/ or /w/ will be assessed relative to the mean across responses from typical participants in the research team's lab-based pilot data. In Task 3, accuracy in category goodness judgment will be assessed relative to the "goldstandard" ratings determined by consensus across at least four expert listeners.
- Secondary Outcome Measures
Name Time Method Perceptually rated accuracy of /r/ production Pre- and 1 week post-treatment To assess generalization of perceptual training to production, participants will be assessed with standard probes administered in the first three baseline sessions and in three post-treatment maintenance sessions. Probes will elicit 30 words \[considered the primary target\], 20 syllables, and 10 sentences containing /r/ in various phonetic contexts. Stimuli in each probe will be presented individually in randomized order. No auditory models will be provided; for children with reading difficulty, semantic cues will be provided to elicit the intended word. Individual words will be isolated from the audio record of each word probe and presented in randomized order for binary rating (1=correct; 0=incorrect) by 9 naive listeners who are blind to treatment condition and time point (but will see the written representation of each target word). The research team will use the proportion of "correct" ratings for each token as our measure of perceptually rated accuracy.
Change in percent accuracy per perception task Pre- and within-treatment (up to one month); pre- and 1 week post-treatment Consistent with the primary analysis, participants' progress will be tracked continuously across baseline and treatment phases using percent accuracy; however, percent accuracy scores will be analyzed separately for comparison between tasks (category goodness judgment and identification tasks) using the same analyses as the primary outcome.
