Do you listen to music while studying? A portrait of how people use music to optimize their cognitive performance

Contains fulltext : 239174.pdf (Publisher’s version ) (Open Access)The effect of background music (BGM) on cognitive task performance is a popular topic. However, the evidence is not converging: experimental studies show mixed results depending on the task, the type of music used and individual characteristics. Here, we explored how people use BGM while optimally performing various cognitive tasks in everyday life, such as reading, writing, memorizing, and critical thinking. Specifically, the frequency of BGM usage, preferred music types, beliefs about the scientific evidence on BGM, and individual characteristics, such as age, extraversion and musical background were investigated. Although the results confirmed highly diverse strategies among individuals regarding when, how often, why and what type of BGM is used, we found several general tendencies: people tend to use less BGM when engaged in more difficult tasks, they become less critical about the type of BGM when engaged in easier tasks, and there is a negative correlation between the frequency of BGM and age, indicating that younger generations tend to use more BGM than older adults. The current and previous evidence are discussed in light of existing theories. Altogether, this study identifies essential variables to consider in future research and further forwards a theory-driven perspective in the field.11 p

Nonlinear Changes in the Rhythm of European Art Music: Quantitative Support for Historical Musicology

Research has used the normalized pairwise variability index (nPVI) to examine relationships between musical rhythm and durational contrast in composers’ native languages. Applying this methodology, linearly increasing nPVI in Austro-German, but not Italian music has recently been ascribed to waning Italian and increasing German influence on Austro-German music after the Baroque Era. The inapplicability of controlled experimental methods to historical data necessitates further replication with more sensitive methods and new repertoire. Using novel polynomial modelling procedures, we demonstrate an initial increase and a subsequent decrease in nPVI in music by 34 French composers. Moreover, previous findings for 21 Austro-German (linear increase) and 15 Italian composers (no change) are replicated. Our results provide promissory quantitative support for accounts from historical musicology of an Italian-dominated Baroque (1600-1750), a Classical Era (1750-1820) with Austro-German centres of gravity (e.g., Mannheim, Vienna), and a Romantic Era (1820-1900) with greater national independence. Future studies should aim to replicate these findings with larger corpora with greater historical representability

Music in Quarantine: Connections Between Changes in Lifestyle, Psychological States, and Musical Behaviors During COVID-19 Pandemic

Music is not only the art of organized sound but also a compound of social interaction among people, built upon social and environmental foundations. Since the beginning of the COVID-19 outbreak, containment measures such as shelter-in-place, lockdown, social distancing, and self-quarantine have severely impacted the foundation of human society, resulting in a drastic change in our everyday experience. In this paper, the relationships between musical behavior, lifestyle, and psychological states during the shelter-in-place period of the COVID-19 pandemic are investigated. An online survey on musical experience, lifestyle changes, stress level, musical behaviors, media usage, and environmental sound perception was conducted. The survey was conducted in early June 2020. Responses from 620 people in 24 countries were collected, with the large proportion of the responses coming from the U.S. (55.5%) and India (21.4%). Structural equation modeling (SEM) analysis revealed causal relationships between lifestyle, stress, and music behaviors. Elements such as stress-level change, work risk, and staying home contribute to changes in musical experiences, such as moderating emotion with music, feeling emotional with music, and being more attentive to music. Stress-level change was correlated with work risk and income change, and people who started living with others due to the outbreak, especially with their children, indicated less change in stress level. People with more stress-level change tended to use music more purposefully for their mental well-being, such as to moderate emotions, to influence mood, and to relax. In addition, people with more stress-level change tend to be more annoyed by neighbors' noise. Housing type was not directly associated with annoyance; however, attention to environmental sounds decreased when the housing type was smaller. Attention to environmental and musical sounds and the emotional responses to them are highly inter-correlated. Multi-group SEM based on musicians showed that the causal relationship structure for professional musicians differs from that of less-experienced musicians. For professional musicians, staying at home was the only component that caused all musical behavior changes; stress did not cause musical behavior changes. Regarding Internet use, listening to music via YouTube and streaming was preferred over TV and radio, especially among less-experienced musicians, while participation in the online music community was preferred by more advanced musicians. This work suggests that social, environmental, and personal factors and limitations influence the changes in our musical behavior, perception of sonic experience, and emotional recognition, and that people actively accommodated the unusual pandemic situations using music and Internet technologies

The Role of Visual Feedback and Creative Exploration for the Improvement of Timing Accuracy in Performing Musical Ornaments

IN DEVELOPING A VISUAL FEEDBACK SYSTEM FOR A CREATIVE activity such as music performance, the objective is not just to reinforce one particular manner of performing. Instead, a desirable characteristic might be that the visual feedback enhances flexibility and originality, in addition to contributing to performance precision. In an experimental study focused on the timing of a musical ornament, we examined whether the instruction to explore ornament timing in training trials with or without visual feedback leads to improved temporal precision in imitating target performances of the ornament, and whether visual feedback enhances the performance diversity during training. The study uncovered distinct strategies of exploration of the performance of the musical ornament and highlighted the dynamics of exploration behavior during training. Visual feedback enhanced exploration of temporal characteristics and influenced imitation accuracy. This study opens up educational possibilities for the training of performance skills and provides direction for further investigation of creative processes in performance

Neural Advantages of Older Musicians Involve the Cerebellum: Implications for Healthy Aging Through Lifelong Musical Instrument Training

This study compared 30 older musicians and 30 age-matched non-musicians to investigate the association between lifelong musical instrument training and age-related cognitive decline and brain atrophy (musicians: mean age 70.8 years, musical experience 52.7 years; non-musicians: mean age 71.4 years, no or less than 3 years of musical experience). Although previous research has demonstrated that young musicians have larger gray matter volume (GMV) in the auditory-motor cortices and cerebellum than non-musicians, little is known about older musicians. Music imagery in young musicians is also known to share a neural underpinning [the supramarginal gyrus (SMG) and cerebellum] with music performance. Thus, we hypothesized that older musicians would show superiority to non-musicians in some of the abovementioned brain regions. Behavioral performance, GMV, and brain activity, including functional connectivity (FC) during melodic working memory (MWM) tasks, were evaluated in both groups. Behaviorally, musicians exhibited a much higher tapping speed than non-musicians, and tapping speed was correlated with executive function in musicians. Structural analyses revealed larger GMVs in both sides of the cerebellum of musicians, and importantly, this was maintained until very old age. Task-related FC analyses revealed that musicians possessed greater cerebellar-hippocampal FC, which was correlated with tapping speed. Furthermore, musicians showed higher activation in the SMG during MWM tasks; this was correlated with earlier commencement of instrumental training. These results indicate advantages or heightened coupling in brain regions associated with music performance and imagery in musicians. We suggest that lifelong instrumental training highly predicts the structural maintenance of the cerebellum and related cognitive maintenance in old age
