Musicians' pursuit of expertise-related goals is characterised by strategic regulation of functional and counterproductive affect.

Background: Emotion regulation is an important part of effective goal pursuit. Functional accounts of emotion regulation suggest that the attainment of challenging goals may be supported by regulating emotions which promote utilitarian over hedonic outcomes. When pursuing the challenging, long-term goal of acquiring expert musical skills and knowledge, musicians may wish to prioritise whichever emotions are most conducive to attaining this goal, even if those emotions are not necessarily positive.

Hierarchical syntax model of music predicts theta power during music listening.

Linguistic research showed that the depth of syntactic embedding is reflected in brain theta power. Here, we test whether this also extends to non-linguistic stimuli, specifically music. We used a hierarchical model of musical syntax to continuously quantify two types of expert-annotated harmonic dependencies throughout a piece of Western classical music: prolongation and preparation.

Translocator protein (TSPO) ligands attenuate mitophagy deficits in the SH-SY5Y cellular model of Alzheimer's disease via the autophagy adaptor P62.

Mitochondrial dysfunction has been widely implicated in the pathogenesis of Alzheimer's disease (AD), with accumulation of damaged and dysfunctional mitochondria occurring early in the disease. Mitophagy, which governs mitochondrial turnover and quality control, is impaired in the AD brain, and strategies aimed at enhancing mitophagy have been identified as promising therapeutic targets. The translocator protein (TSPO) is an outer mitochondrial membrane protein that is upregulated in AD, and ligands targeting TSPO have been shown to exert neuroprotective effects in mouse models of AD.

Interpreting Rhythm as Parsing: Syntactic-Processing Operations Predict the Migration of Visual Flashes as Perceived During Listening to Musical Rhythms.

Music can be interpreted by attributing syntactic relationships to sequential musical events, and, computationally, such musical interpretation represents an analogous combinatorial task to syntactic processing in language. While this perspective has been primarily addressed in the domain of harmony, we focus here on rhythm in the Western tonal idiom, and we propose for the first time a framework for modeling the moment-by-moment execution of processing operations involved in the interpretation of music. Our approach is based on (1) a music-theoretically motivated grammar formalizing the competence of rhythmic interpretation in terms of three basic types of dependency (preparation, syncopation, and split; Rohrmeier, 2020), and (2) psychologically plausible predictions about the complexity of structural integration and memory storage operations, necessary for parsing hierarchical dependencies, derived from the dependency locality theory (Gibson, 2000).

Thematic Contents of Mental Imagery are Shaped by Concurrent Task-Irrelevant Music.

Imagination plays a key role in evidence-based, cognitive therapies, and recent research highlights that music - a perceptual stimulus imbued with affective and social meaning - can influence some aspects of imagination, such as vividness and emotional tone. However, little is known about music's capability to facilitate specific imagery themes that may be relevant for therapy. Here, we examine whether the quantity and quality (related to themes of affect, social dynamics, and confidence) of people's imagery is affected by the presence of task-irrelevant background music.

Emotional cherry picking: the role of personality and goal orientation in selective emotion regulation for musical practice.

Introduction: Emotion regulation is an important part of optimising performance and successful goal pursuit in practice-based tasks such as making music. Musicians may regulate their own emotions during the course of their musical practice in order to improve their performance and ultimately attain their practice-related goals. The specific emotions they target may depend upon their personality traits but may also relate to the nature of their goal orientation, and the interaction between the two.

Information processing biases: The effects of negative emotional symptoms on sampling pleasant and unpleasant information.

Although theories of emotion associate negative emotional symptoms with cognitive biases in information processing, they rarely specify the details. Here, we characterize cognitive biases in information processing of and information, and how these biases covary with anxious and depressive symptoms, while controlling for general stress and cognitive ability. Forty undergraduates provided emotional symptom scores (Depression Anxiety Stress Scale-21) and performed a statistical learning task that required predicting the next sound in a long sequence of either or naturalistic sounds (blocks).

Musical Garden Paths: Evidence for Syntactic Revision Beyond the Linguistic Domain.

While theoretical and empirical insights suggest that the capacity to represent and process complex syntax is crucial in language as well as other domains, it is still unclear whether specific parsing mechanisms are also shared across domains. Focusing on the musical domain, we developed a novel behavioral paradigm to investigate whether a phenomenon of syntactic revision occurs in the processing of tonal melodies under analogous conditions as in language. We present the first proof-of-existence for syntactic revision in a set of tonally ambiguous melodies, supporting the relevance of syntactic representations and parsing with language-like characteristics in a nonlinguistic domain.

The influence of anodal transcranial direct current stimulation over the right auditory cortex on interference effects in memory for melodies.

The study investigates how transcranial direct current stimulation (tDCS) over the auditory cortex (AC) modulates memory for melodies under different noise conditions, whilst also considering cumulative disruptive interference effects. Forty-one participants completed a continuous recognition melody task, as well as a visual control task, which included four noise conditions for which noise was either present only during encoding (N-C), only during retrieval (C-N), during both (N-N) or not at all (C-C) and completed the tasks after receiving anodal or sham tDCS over the right AC. The results of the sham session replicate previous findings by revealing that memory for melodies is worse when noise in added to the encoding phase (N-C) whereas the N-N condition shows good performance, highlighting a context effect, and that cumulative disruptive interference is not present in memory for melodies except in the N-C condition.

Corrigendum: Expertise-Related Differences in Wrist Muscle Co-contraction in Drummers.

Music influences vividness and content of imagined journeys in a directed visual imagery task.

Directed, intentional imagination is pivotal for self-regulation in the form of escapism and therapies for a wide variety of mental health conditions, such anxiety and stress disorders, as well as phobias. Clinical application in particular benefits from increasing our understanding of imagination, as well as non-invasive means of influencing it. To investigate imagination, this study draws from the prior observation that music can influence the imagined content during non-directed mind-wandering, as well as the finding that relative orientation within time and space is retained in imagination.

The effect of low-frequency equalisation on preference and sensorimotor synchronisation in music.

Equalisation, a signal processing technique commonly used to shape the sound of music, is defined as the adjustment of the energy in specific frequency components of a signal. In this work, we investigate the effects of equalisation on preference and sensorimotor synchronisation in music. A total of 21 participants engaged in a goal-directed upper body movements in synchrony with stimuli equalised in three low-frequency sub-bands (0-50, 50-100, and 100-200 Hz).

Expertise-Related Differences in Wrist Muscle Co-contraction in Drummers.

Drumming requires excellent motor control and temporal coordination. Deploying specific muscle activation patterns may help achieve these requirements. Muscle activation patterns that involve reciprocal contraction of antagonist muscles are particularly favorable as they enable a high level of muscular economy while maintaining performance.

Age-dependent statistical learning trajectories reveal differences in information weighting.

Statistical learning (SL) is the ability to generate predictions based on probabilistic dependencies in the environment, an ability that is present throughout life. The effect of aging on SL is still unclear. Here, we explore statistical learning in healthy adults (40 younger and 40 older).

The perceptual relevance of balance, evenness, and entropy in musical rhythms.

There is an uncountable number of different ways of characterizing almost any given real-world stimulus. This necessitates finding stimulus features that are perceptually relevant - that is, they have distinct and independent effects on the perception and cognition of the stimulus. Here, we provide a theoretical framework for empirically testing the perceptual relevance of stimulus features through their association with recognition, memory bias, and æsthetic evaluation.

Memory for melodies in unfamiliar tuning systems: Investigating effects of recency and number of intervening items.

In a continuous recognition paradigm, most stimuli elicit superior recognition performance when the item to be recognized is the most recent stimulus (a recency-in-memory effect). Furthermore, increasing the number of intervening items cumulatively disrupts memory in most domains. Memory for melodies composed in familiar tuning systems also shows superior recognition for the most recent melody, but no disruptive effects from the number of intervening melodies.

Negotiating between individual and joint goals in ensemble musical performance.

Successful joint action requires negotiation, especially in the event of goal incongruence. This article addresses goal incongruence in joint musical performance by manipulating the congruence of score instructions (congruent/incongruent) regarding tempo (speed) and dynamics (sound intensity) given to piano duos. The aim is to investigate how co-performers negotiate incongruent instructions for tempo and dynamics by balancing the prioritisation of individual goals versus the joint outcome and how this negotiation is modulated by musical expertise and personality (locus of control).

Resilient memory for melodies: The number of intervening melodies does not influence novel melody recognition.

In many memory domains, a decrease in recognition performance between the first and second presentation of an object is observed as the number of intervening items increases. However, this effect is not universal. Within the auditory domain, this form of interference has been demonstrated in word and single-note recognition, but has yet to be substantiated using relatively complex musical material such as a melody.
