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.

Intervention

Intervention Type: Behavioral

Intervention Name: Perceptual training

Description: Perceptual training involves self-paced presentation of auditory stimuli via a computerized software program. Stimuli are organized into three separate tasks: Tasks 1 and 3 will train category goodness judgment: Participants will hear 75 naturally produced speech tokens containing /r/ from various speakers, with a balance of correct and incorrect productions. They will classify each /r/ as correct or incorrect and receive feedback on the accuracy of their classification. Tasks 1 and 3 differ in that task 1 will feature a subset of items designed to provide focused practice on a specific context (e.g., initial /r/ as in red; /r/ as syllable nucleus as in sir), with increasing difficulty over time, whereas task 3 will feature randomly selected items representing all contexts and difficulty levels. Task 2: Participants will hear 75 items drawn from the synthetic rake-wake continuum used in the identification task administered at baseline.

Arm Group Label: Online Speech Training

Intervention Type: Behavioral

Intervention Name: Production training

Description: Instruction: Discuss tongue shapes for /r/. Pre-practice: relatively unstructured, highly interactive elicitation; provide models and placement cue and KP on every trial. Structured syllable practice: Practice will occur in blocks of 10 consecutive trials on the same syllable (e.g., 10 /ra/), after which a new syllable will be addressed (e.g., 10 /re/--but note that in the fully blocked condition, the same syllable should occur in two consecutive blocks of 10).

Type: Experimental

Description: 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.

Study Design Info

Allocation: N/A

Intervention Model: Single Group Assignment

Intervention Model Description: This study follows a multiple-baseline across-subjects design with random assignment of participants to different baseline durations. 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. Perception will be measured using the online identification and category goodness tasks and production will be measured from standard probes (20 syllables, 30 words, and 10 sentences containing /r/ in various phonetic contexts). 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 followed by 4 sessions of production training over 2 weeks.

Primary Purpose: Treatment
