Data accompanying the Registered Report: Does unfairness sound wrong? A cross-domain investigation of expectations in music and social decision-making.

This study was interested in investigating the existence of a shared psychological mechanism for the processing of expectations across domains. The literature on music and language shows that violations of expectations produce similar neural responses and violating the expectation in one domain may influence the processing of stimuli in the other domain. Like music and language, our social world is governed by a system of inherent rules or norms, such as fairness. The study therefore aimed to draw a parallel to the social domain and investigate whether a manipulation of melodic expectation can influence the processing of higher-level expectations of fairness. Specifically, we aimed to investigate whether the presence of an unexpected melody enhances or reduces participants’ sensitivity to the violations of fairness and the behavioural reactions associated with these. We embedded a manipulation of melodic expectation within a social decision-making paradigm, whereby musically expected an...本研究旨在探究跨领域预期加工的共享心理机制是否存在。现有音乐与语言领域的研究文献显示，预期违反会引发相似的神经反应（neural responses），且在某一领域违反预期，可能会影响另一领域的刺激加工。与音乐和语言类似，人类社会同样受一套内在规则与规范体系支配，例如公平准则（fairness）。因此，本研究旨在类比社会领域，探究旋律预期（melodic expectation）的操纵是否会影响个体对公平这一高阶预期的加工。具体而言，本研究旨在探究意外旋律的出现，是否会增强或减弱被试（participants）对公平违反行为的敏感性，以及与此类违反行为相关的行为反应。我们将旋律预期操纵嵌入社会决策范式（social decision-making paradigm）中，其中音乐预期为……
