The impacts of music training and music sophistication on empathy

共情能力是预测和促进亲社会行为的重要因素,音乐经验对共情能力的发展有着重要作用。本研究以特质共情和状态共情两个方面为切入点,采用音乐训练和音乐素养两个指标衡量个体音乐经验,利用问卷调查和行为实验,探究它们对共情能力的影响路径。结果表明,在特质共情方面,音乐家的认知共情能力显著高于非音乐家。然而,在控制了人格、主观社会经济地位和心理健康状态的相关变量后,音乐训练对共情能力并无显著影响。相反,音乐素养显著正向预测认知共情能力的想象维度,甚至可以作为音乐训练影响认知共情中想象维度的中介变量。在状态共情方面,利用疼痛共情范式研究发现,相比非音乐家,音乐家在目睹他人疼痛情境时更能感同身受,这种状态共情能力受到音乐素养和特质认知共情中想象维度的链式中介影响。综上所述,音乐训练通过提高音乐素养,间接增强特质共情中的认知共情能力(想象),从而使音乐家在感同身受他人疼痛状态时表现出更强的能力。这些发现揭示了音乐经验对共情能力的促进机制。</p

Measurement of integrated luminosity of data collected at 3.773 GeV by BESIII from 2021 to 2024

We present a measurement of the integrated luminosity e+e- of collision data collected by the BESIII detector at the BEPCII collider at a center-of-mass energy of Ecm = 3.773 GeV. The integrated luminosities of the datasets taken from December 2021 to June 2022, from November 2022 to June 2023, and from October 2023 to February 2024 were determined to be 4.995±0.019 fb-1, 8.157±0.031 fb-1, and 4.191±0.016 fb-1, respectively, by analyzing large angle Bhabha scattering events. The uncertainties are dominated by systematic effects, and the statistical uncertainties are negligible. Our results provide essential input for future analyses and precision measurements

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
