Experiencing a sense of agency (SoA), the feeling of being in control over one's actions and their outcomes, typically requires intentional and voluntary actions. Prior research has compared the association of voluntary versus completely involuntary actions with the SoA. Here, we leveraged unique characteristics of oculomotor actions to partially manipulate the degree of action voluntariness. Participants performed either highly automatized prosaccades or highly controlled (voluntary) anti-saccades, triggering a gaze-contingent visual action effect. We assessed explicit SoA ratings and temporal action and effect binding as an implicit SoA measure. Anti-saccades were associated with stronger action binding compared to prosaccades, demonstrating a robust association between higher action voluntariness and a stronger implicit sense of action agency. We conclude that our manipulation of action voluntariness may have impacted the implicit phenomenological feeling of bodily agency, but it did not affect the SoA over effect outcomes or explicit agency perception.
体验能动性（SoA），即对自身行为及其结果的掌控感，通常需要有意的和自愿的行动。先前的研究比较了自愿行动与完全非自愿行动与能动性的关联。在此，我们利用眼动动作的独特特征来部分操纵行动的自愿程度。参与者执行高度自动化的前扫视或高度可控（自愿）的反扫视，触发基于注视的视觉动作效应。我们评估了明确的能动性评分以及时间上的动作与效应绑定作为一种隐性能动性测量方法。与前扫视相比，反扫视与更强的动作绑定相关联，表明更高的行动自愿性与更强的隐性行动能动性之间存在稳健的关联。我们得出结论，我们对行动自愿性的操纵可能影响了身体能动性的隐性现象学感受，但并未影响对效应结果的能动性或明确的能动性感知。
