The Musical Emotion Discrimination Task (MEDT) is a short, non-adaptive test of the ability to discriminate emotions in music. Test-takers hear two performances of the same melody, both played by the same performer but each trying to communicate a different basic emotion, and are asked to determine which one is "happier", for example. The goal of the current study was to construct a new version of the MEDT using a larger set of shorter, more diverse music clips and an adaptive framework to expand the ability range for which the test can deliver measurements. The first study analysed responses from a large sample of participants (= 624) to determine how musical features contributed to item difficulty, which resulted in a quantitative model of musical emotion discrimination ability rooted in Item Response Theory (IRT). This model informed the construction of the adaptive MEDT. A second study contributed preliminary evidence for the validity and reliability of the adaptive MEDT, and demonstrated that the new version of the test is suitable for a wider range of abilities. This paper therefore presents the first adaptive musical emotion discrimination test, a new resource for investigating emotion processing which is freely available for research use.
音乐情绪辨别任务（MEDT）是一种简短的、非自适应的测试，用于测试个体辨别音乐中情绪的能力。测试者会听到同一旋律的两次演奏，由同一位演奏者演奏，但每次演奏都试图传达不同的基本情绪，然后被要求判断哪一个更“快乐”，例如。本研究的目的是使用更大的、更短的、更多样化的音乐片段和自适应框架构建一个新的 MEDT 版本，以扩展测试可以提供测量结果的能力范围。第一项研究分析了来自大量参与者（=624）的反应，以确定音乐特征如何影响项目难度，这导致了一个基于项目反应理论（IRT）的音乐情绪辨别能力的定量模型。该模型为自适应 MEDT 的构建提供了信息。第二项研究为自适应 MEDT 的有效性和可靠性提供了初步证据，并证明了新版本的测试适用于更广泛的能力范围。因此，本文介绍了第一个自适应音乐情绪辨别测试，这是一个用于研究情绪处理的新资源，可供研究使用。
