When attention is divided during memory encoding, performance tends to suffer. The nature of this performance decrement, however, is domain-dependent and often governed by domain-specific expertise. In this study, 111 participants with differing levels of musical expertise (professional musicians, amateur musicians, and non-musicians) were presented with novel melodies under full- or divided-attention conditions in a continuous melody-recognition task. As hypothesized, melody recognition was modulated by musical expertise, as greater expertise was associated with better performance. Recognition performance increased with every additional presentation of a target melody. The divided-attention condition required concurrently performing a non-music related digit-monitoring task while simultaneously listening to the melodies. Memory performance decreased universally in all groups in the divided-attention condition; however, intriguingly musicians also performed significantly better in the concurrent digit-monitoring task than non-musicians. Results provide insight into the role of expertise, attention, and memory in the musical domain, and are discussed in terms of attentional resource models. In light of resource models, an asymmetrical non-linear trade-off between two simultaneous tasks is proposed to explain the present findings.

Abstract The main focus of the paper is the role of listeners’ emotion-relevant characteristics and musical expertise in the granularity of affective responses to music. Another objective of the study is to test the consistency of the granularity of affect that is perceived in music and/or experienced in response to it. In Experiment 1, 91 musicians and nonmusicians listened to musical excerpts and grouped them according to the similarity of the affects they experienced while listening. Finer grouping granularity was found in musicians and high rumination scorers. Male musicians with above-median scores in rumination produced a larger number of clusters than the other male participants. Experiment 2 that engaged 23 participants demonstrated moderate consistency with which listeners grouped affects that they perceived in music and affects they experienced while listening to music. The study suggests that affective responses to music are subject to individual differences in musical expertise and rumination. Affects perceived in music and felt in response to it seem to be categorized with reference to the common principles. However, the cues that are used in such instances of categorization seem to be different. The paper encourages further research on the importance of listeners’ personal characteristics for the affective responses to music.

Perceptual Changes

The pupil provides a rich, non-invasive measure of the neural bases of perception and cognition. It can particularly inform about the role of arousal-linked neuromodulation, which alters both cortical processing and pupil size. But a multitude of factors influence pupil size, which complicates interpretation. We measured pupil signals accompanying changes in multistable perception, i.e. accompanying endogenously-generated perceptual changes in the face of inconclusive sensory input. Perceptual changes were marked by a complex pupil response that could be decomposed into two components: a dilation tied to task execution and plausibly reflecting arousal-linked noradrenaline, and an overlapping constriction tied to the perceptual transient and plausibly reflecting altered cortical responses. Constriction, but not dilation, amplitude depended on the timing of perceptual changes, possibly providing an index of neural adaptation. We conclude that pupil size reflects several dissociable processes during perceptual multistability, and that arousal-linked neuromodulation shapes action but not perception in these circumstances.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.
