Auditory Learning and Generalization in Older Adults: Evidence from Voice Discrimination Training.
Auditory learning is essential for adapting to continuously changing acoustic environments. This adaptive capability, however, may be impacted by age-related declines in sensory and cognitive functions, potentially limiting learning efficiency and generalization in older adults. This study investigated auditory learning and generalization in 24 older (65-82 years) and 24 younger (18-34 years) adults through voice discrimination (VD) training. Participants were divided into training (12 older, 12 younger adults) and control groups (12 older, 12 younger adults). Trained participants completed five sessions: Two testing sessions assessing VD performance using a 2-down 1-up adaptive procedure with F0-only, formant-only, and combined F0 + formant cues, and three training sessions focusing exclusively on VD with F0 cues. Control groups participated only in the two testing sessions, with no intermediate training. Results revealed significant training-induced improvements in VD with F0 cues for both younger and older adults, with comparable learning efficiency and gains across groups. However, generalization to the formant-only cue was observed only in younger adults, suggesting limited learning transfer in older adults. Additionally, VD training did not improve performance in the combined F0 + formant condition beyond control group improvements, underscoring the specificity of perceptual learning. These findings provide novel insights into auditory learning in older adults, showing that while they retain the ability for significant auditory skill acquisition, age-related declines in perceptual flexibility may limit broader generalization. This study highlights the importance of designing targeted auditory interventions for older adults, considering their specific limitations in generalizing learning gains across different acoustic cues.

期刊介绍:
Trends in Hearing is an open access journal completely dedicated to publishing original research and reviews focusing on human hearing, hearing loss, hearing aids, auditory implants, and aural rehabilitation. Under its former name, Trends in Amplification, the journal established itself as a forum for concise explorations of all areas of translational hearing research by leaders in the field. Trends in Hearing has now expanded its focus to include original research articles, with the goal of becoming the premier venue for research related to human hearing and hearing loss.
