Auditory-Perceptual Training Via Telepractice

"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."

"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)."
