    Long-term musical experience and auditory and visual perceptual abilities under adverse conditions
    (ASA, 2016-09) Anaya, Esperanza M.; Pisoni, David B.; Kronenberger, William G.; Department of Psychiatry, IU School of Medicine
    Musicians have been shown to have enhanced speech perception in noise skills. It is unclear whether these improvements are limited to the auditory modality, as no research has examined musicians' visual perceptual abilities under degraded conditions. The current study examined associations between long-term musical experience and visual perception under noisy or degraded conditions. The performance of 11 musicians and 11 age-matched nonmusicians was compared on several auditory and visual perceptions in noise measures. Auditory perception tests included speech-in-noise tests and an environmental sound in noise test. Visual perception tasks included a fragmented sentences task, an object recognition task, and a lip-reading measure. Participants' vocabulary knowledge and nonverbal reasoning abilities were also assessed. Musicians outperformed nonmusicians on the speech perception in noise measures as well as the visual fragmented sentences task. Musicians also displayed better vocabulary knowledge in comparison to nonmusicians. Associations were found between perception of speech and visually degraded text. The findings show that long-term musical experience is associated with modality-general improvements in perceptual abilities. Possible systems supporting musicians' perceptual abilities are discussed.

    Visual-spatial sequence learning and memory in trained musicians
    (Sage, 2017-01) Anaya, Esperanza M.; Pisoni, David B.; Kronenberger, William G.; Psychiatry, School of Medicine
    Previous research has shown that musicians have enhanced visual-spatial abilities and sensorymotor skills. As a result of their long-term musical training and their experience-dependent activities, musicians may learn to associate sensory information with fine motor movements. Playing a musical instrument requires musicians to rapidly translate musical symbols into specific sensory-motor actions while also simultaneously monitoring the auditory signals produced by their instrument. In this study, we assessed the visual-spatial sequence learning and memory abilities of long-term musicians. We recruited 24 highly trained musicians and 24 nonmusicians, individuals with little or no musical training experience. Participants completed a visual-spatial sequence learning task as well as receptive vocabulary, nonverbal reasoning, and short-term memory tasks. Results revealed that musicians have enhanced visual-spatial sequence learning abilities relative to nonmusicians. Musicians also performed better than nonmusicians on the vocabulary and nonverbal reasoning measures. Additional analyses revealed that the large group difference observed on the visualspatial sequencing task between musicians and nonmusicians remained even after controlling for vocabulary, nonverbal reasoning, and short-term memory abilities. Musicians' improved visualspatial sequence learning may stem from basic underlying differences in visual-spatial and sensorymotor skills resulting from long-term experience and activities associated with playing a musical instrument.
