Music and Visual Art Training Increase Auditory-Evoked Theta Oscillations in Older Adults.

Music training was shown to induce changes in auditory processing in older adults. However, most findings stem from correlational studies and fewer examine long-term sustainable benefits. Moreover, research shows small and variable changes in auditory event-related potential (ERP) amplitudes and/or latencies in older adults. Conventional time domain analysis methods, however, are susceptible to latency jitter in evoked responses and may miss important information of brain processing. Here, we used time-frequency analyses to examine training-related changes in auditory-evoked oscillatory activity in healthy older adults (N = 50) assigned to a music training (n = 16), visual art training (n = 17), or a no-treatment control (n = 17) group. All three groups were presented with oddball auditory paradigms with synthesized piano tones or vowels during the acquisition of high-density EEG. Neurophysiological measures were collected at three-time points: pre-training, post-training, and at a three-month follow-up. Training programs were administered for 12-weeks. Increased theta power was found pre and post- training for the music (p = 0.010) and visual art group (p = 0.010) as compared to controls (p = 0.776) and maintained at the three-month follow-up. Results showed training-related plasticity on auditory processing in aging adults. Neuroplastic changes were maintained three months post-training, suggesting music and visual art programs yield lasting benefits that might facilitate encoding, retention, and memory retrieval.

Multimodal music training enhances executive functions in children: Results of a randomized controlled trial.

Music training programs have shown mixed results on children's executive functions. The purpose of the present study was to evaluate the impact of a 10-week multimodal music program with vocal development, bimanual coordination, and musical improvisation, on children's executive functions. We hypothesized that a 10-week music program would enhance executive functions in working memory in 4- to 6-year-old children. Eighty-four children were randomly assigned to a multimodal music program, an active control Lego program, or no treatment control condition (i.e., randomized controlled design). All children completed measures of music aptitude, music achievement, and executive functions (i.e., EF Touch) pre- and post-training. Results revealed enhanced pitch accuracy and working memory for children in the music training group as compared to the other conditions. Children in the Lego condition demonstrated significant enhancements of spatial working memory. Tonal music aptitude significantly predicted performance on measures of working memory. Contributions to the literature include the randomized controlled design, group multimodal music program appropriate for 4- to 6-year-old children, and the use of executive function measures sensitive to individual differences.

Feasibility and Acceptability of a Group Music Intervention in Memory Care Communities.

Music-based interventions have been shown to reduce behavioral expressions among persons with dementia. The goal of this study was to examine the feasibility and acceptability of a group music intervention to reduce agitation. Two memory care communities were recruited to participate in this single-arm mixed-methods study. The group music intervention program included a total of 12 sessions delivered over 4 weeks. Agitation was assessed quantitatively at weeks 0, 2, and 4. Qualitative interviews of memory care staff were conducted post-intervention. Data were analyzed using linear mixed-effects models and qualitative content analysis. The study sample (N = 19) had a mean age of 82.74, and 73.7% were female. The great majority of participants completed the intervention and 63.2% experienced a reduction in agitation, suggesting that the intervention is feasible and acceptable in memory care and may be efficacious. Future research should evaluate the efficacy of the intervention in a randomized controlled trial.

Piano Training Enhances Executive Functions and Psychosocial Outcomes in Aging: Results of a Randomized Controlled Trial.

OBJECTIVES: Preliminary evidence suggests that piano training may enhance areas of executive functions and psychosocial outcomes in aging adults. However, little is known regarding specific cognitive outcomes affected and whether or not enhancements are sustainable. We conducted a randomized controlled trial to evaluate the effects of piano training on cognitive performance, psychosocial well-being, and physiological stress and immune function in older adults. METHODS: Older adults (N = 155, 60-80 years) completed an initial 3-h assessment of standardized cognitive and psychosocial measures. Participants were randomly assigned to one of the 3 groups: piano training, computer-assisted cognitive training, or a no-treatment control group. Training groups completed a 16-week program with 2 group training sessions per week for 90 min each session. All participants completed a standard battery of executive functions (working memory, processing speed, verbal fluency), psychosocial measures (musical and general self-efficacy, mood), and physiological measures (cortisol and immune function) at pretesting, posttesting, and at a 3-month follow-up time point. RESULTS: The results showed that piano training and computer-assisted cognitive training enhanced working memory and processing speed as compared to controls. Piano training significantly increased verbal fluency skills in category switching, as compared to computer-assisted cognitive training and no-treatment controls. Participants in piano training demonstrated enhanced general and musical self-efficacy posttraining; however, no significant differences were found for physiological measures. DISCUSSION: Piano training resulted in a unique advantage in category switching as compared to computer-assisted cognitive training and no-treatment controls. Music training programs may mitigate or prevent cognitive deficits in verbal skills. CLINICAL TRIAL REGISTRATION: NCT02564601.

Association Between Music Engagement and Episodic Memory Among Middle-Aged and Older Adults: A National Cross-Sectional Analysis.

OBJECTIVES: To determine whether music engagement influences middle-aged and older adults' performance on episodic memory tasks. METHOD: Secondary data analysis of a sample (N = 4,592) of cognitively healthy adults from the 2016 Health and Retirement Study was used for this study. Multivariable regression models were used to analyze the cross-sectional differences in performance on tasks of episodic memory between participants who listened to music (n = 3,659) or sang or played an instrument (n = 989). RESULTS: On average, participants recalled 10.3 words out of a possible 20. Regression analyses showed that both listening to music and singing or playing an instrument were independently associated with significantly better episodic memory. DISCUSSION: The findings provide the first population-based evidence that music engagement is associated with better episodic memory among middle-aged and older adults. Future studies should examine whether the relationship between music engagement and episodic memory can be replicated in other populations and that the association persists in longitudinal studies.

Music is similar to language in terms of working memory interference.

Some researchers theorize that musicians' greater language ability is mediated by greater working memory because music and language share the same processing resources. Prior work using working memory sentence processing dual-task paradigms have shown that holding verbal information (e.g., words) in working memory interferes with sentence processing. In contrast, visuospatial stimuli are processed in a different working memory store and should not interfere with sentence processing. We tested whether music showed similar interference to sentence processing as opposed to noninterference like visuospatial stimuli. We also compared musicians to nonmusicians to investigate whether musical training improves verbal working memory. Findings revealed that musical stimuli produced similar working memory interference as linguistic stimuli, but visuospatial stimuli did not-suggesting that music and language rely on similar working memory resources (i.e., verbal skills) that are distinct from visuospatial skills. Musicians performed more accurately on the working memory tasks, particularly for the verbal and musical working memory stimuli, supporting an association between musicianship and greater verbal working memory capacity. Future research is necessary to evaluate the role of music training as a cognitive intervention or educational strategy to enhance reading fluency.

The Effects of Bimanual Coordination in Music Interventions on Executive Functions in Aging Adults.

Music training programs have been shown to enhance executive functions in aging adults; however, little is known regarding the extent to which different types of bimanual coordination (i.e., fine and gross motor) in music instruction contribute to these outcomes. The aim of this study was to examine the effects of bimanual coordination in music interventions on cognitive performance in healthy older adults (60-80 years). Participants (N = 135) completed motor measures and battery of standardized cognitive measures, before and after a 16-week music training program with a 3 h practice requirement. All participants were matched by age, education, and estimate of intelligence to one of three training programs: piano training (fine motor); percussion instruction (gross motor), and music listening instruction (MLI) (no motor control condition). Results of a Repeated Measures ANOVA revealed significant enhancements in bimanual synchronization and visual scanning/working memory abilities for fine and gross motor training groups as compared to MLI. Pairwise comparisons revealed that piano training significantly improved motor synchronization skills as compared to percussion instruction or music listening. Results suggest that active music performance may benefit working memory, the extent of these benefits may depend upon coordination demands.

A Rationale for Music Training to Enhance Executive Functions in Parkinson's Disease: An Overview of the Problem.

Music listening interventions such as Rhythmic Auditory Stimulation can improve mobility, balance, and gait in Parkinson’s Disease (PD). Yet, the impact of music training on executive functions is not yet known. Deficits in executive functions (e.g., attention, processing speed) in patients with PD result in gait interference, deficits in emotional processing, loss of functional capacity (e.g., intellectual activity, social participation), and reduced quality of life. The model of temporal prediction and timing suggests two networks collectively contribute to movement generation and execution: the basal ganglia-thalamocortical network (BGTC) and the cerebellar-thalamocortical network (CTC). Due to decreases in dopamine responsible for the disruption of the BGTC network in adults with PD, it is hypothesized that rhythmic auditory cues assist patients through recruiting an alternate network, the CTC, which extends to the supplementary motor areas (SMA) and the frontal cortices. In piano training, fine motor finger movements activate the cerebellum and SMA, thereby exercising the CTC network. We hypothesize that exercising the CTC network through music training will contribute to enhanced executive functions. Previous research suggested that music training enhances cognitive performance (i.e., working memory and processing speed) in healthy adults and adults with cognitive impairments. This review and rationale provides support for the use of music training to enhance cognitive outcomes in patients with Parkinson’s Disease (PD).

Intense piano training on self-efficacy and physiological stress in aging.

The aim of this study was to evaluate the effects of an intense piano training program on general self-efficacy, musical self-efficacy, and physiological stress in older adults. Self-efficacy refers to perceived beliefs regarding the performance of domain-specific tasks or activities, which contribute to psychological and physical health. A key challenge is to identify activities that promote self-efficacy in the aging population. Seventeen healthy community-dwelling older adults (60-85 years) with little to no previous musical training participated in a within subjects experimental design. Measures of self-efficacy and cortisol levels were administered over three time points: an initial pre-testing session, a second pre-testing following a two-week no treatment control period, and a post-testing session upon the completion of piano training. Intense piano training consisted of 30 hours of training (3 hours per day) in which high levels of achievement were required. Results of a three-way Repeated Measures ANOVA over all time points with pairwise comparisons revealed significantly (p < .05) enhanced musical self-efficacy post-training, F (2, 32) = 11.5, p < .001, d = .79. No significant changes in general self-efficacy or cortisol levels were found. These results suggest that domain-specific self-efficacy may increase as a result of short-term intense music training; however, short-term music training may not be sufficient to transfer to general self-efficacy.
