简要总结
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.
详细描述
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 3 to 9 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.

研究组 & 干预措施
Online Speech Training
Participants will be randomly assigned to transition from the baseline to the treatment condition at one of 7 possible points, ranging from 3 to 9 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.

结局指标
主要结局
Averaged Perception Percent Accuracy Score
时间窗: Participants' perception progress was tracked across all treatment phases. The averaged percent accuracy score reported here was collected during maintenance sessions (3 sessions across 1 week).
Averaged percent accuracy post-perception training.
次要结局
- Raw Change in Percent Accuracy Perception Task(Participants' progress was tracked across pre-treatment phase (averaged baselines) compared to post treatment phase (averaged three maintenance sessions which occurred over 1 week), up to 8 weeks, including baselines, treatment, and maintenance sessions.)
- Perceptually Rated Accuracy of /r/ Word Production(Participants' progress was tracked across pre-treatment phase (averaged baselines) compared to post treatment phase (averaged three maintenance sessions which occurred over 1 week), up to 8 weeks, including baselines, treatment, and maintenance sessions.)
