Studies on the effect of music on task performance are contradictory about this relationship’s direction and valence. Task characteristics may be accounting for these inconclusive findings. Thus, this study employs effort to mediate music’s effect on task performance (objective and perceived) under a stressful decision-making process. This is a between-group experiment with three conditions: slow-tempo music, fast-tempo music, or no music. We designed a computer web interface, where participants did a stressful task. Results demonstrated that participants made a strong effort under the conditions with music. Hence, turning the music off under stressful activities is favorable in terms of performance. The article contributes to understanding the interaction between music and task performance, expanding the discussion within a stressful task.

关于音乐对任务绩效的影响的研究与这种关系的方向和效价是矛盾的。任务特征可能是造成这些不确定结论的原因。因此，本研究在压力较大的决策过程中努力调解音乐对任务绩效（客观和感知）的影响。这是具有三个条件的组间实验：慢速音乐，快速音乐或无音乐。我们设计了一个计算机Web界面，参与者在其中完成了繁重的任务。结果表明，参与者在有音乐的条件下付出了巨大的努力。因此，就表现而言，在紧张的活动中关闭音乐是有利的。本文有助于理解音乐和任务表现之间的相互作用，并在压力很大的任务中扩大讨论范围。
