The Efficacy of Transfer of Learning and Retention with Short-Term Auditory Training: Evidences from Auditory Evoked Potential and Behavioral Tests

Purpose: The purpose of this study was to investigate whether short-term auditory training is associated with transfer of learning and retention through behavioral and auditory evoked potential tests the efficacy of short-term auditory training the efficacy. Methods: A total of twenty adult listeners with normal-hearing participated. Among them, eleven participants were randomly assigned as the experimental group. Two pairs of synthesized consonant-vowel (CV) were used, and only one pair of CV was used for the 20-minute auditory training. For the experimental group, behavioral tests and the mismatch negativity (MMN) were assessed using two pairs of CV sounds before and right after the auditory training. For the control group, behavioral and MMN were assessed twice with a 20-minute interval, without any auditory training. Also, all the tests were reassessed in one week after the training only for the experimental group. Results: In the experimental group, scores of the behavioral test increased significantly after the short auditory training for both stimuli sets (trained and untrained CV pairs). Onset latency and duration of MMN were significantly changed when elicited by both stimuli sets. Also, behavioral and MMN results were not significantly changed in one week after the auditory training. There were no significant changes in behavioral scores and onset latency and duration of MMN for the experimental group. Conclusion: The present findings support that short-term auditory training produced significant training effects in terms of transfer of learning and retention.
