The sense of agency (SoA) refers to the subjective experience of influencing the external world through actions. This study explores how action selection and simultaneous affective outcomes impact implicit and explicit SoA. In two experiments, participants performed free or instructed key presses followed by simultaneously presenting a reward picture (gain, loss) with an emotional sound (positive, neutral, negative). Experiment 1 showed enhanced implicit SoA for free (vs. instructed) actions and positive (vs. negative) sound. Experiment 2 revealed enhanced explicit SoA for reward gain (vs. loss) and positive (vs. negative) sound. Results suggest that SoA formation at different consciousness levels depends on various cues' absolute and relative strengths. Action selection only influenced implicit SoA, while affective outcomes showed differential effects: emotional sound impacted implicit SoA, and both reward and sound influenced explicit SoA, with motivation-related reward showing stronger effects. This research advances the understanding of cue integration mechanisms underlying SoA formation.
能动感（SoA）是指通过行动影响外部世界的主观体验。本研究探讨了行动选择和同时出现的情感结果如何影响内隐和外显的能动感。在两项实验中，参与者进行自由或指令性按键，随后同时呈现带有情感声音（积极、中性、消极）的奖励图片（获得、损失）。实验1表明，自由（相对于指令性）行动和积极（相对于消极）声音会增强内隐能动感。实验2显示，奖励获得（相对于损失）和积极（相对于消极）声音会增强外显能动感。结果表明，不同意识水平下的能动感形成取决于各种线索的绝对和相对强度。行动选择仅影响内隐能动感，而情感结果则显示出不同的影响：情感声音影响内隐能动感，奖励和声音都影响外显能动感，与动机相关的奖励显示出更强的影响。这项研究推进了对能动感形成背后线索整合机制的理解。
