Sense of agency (SoA) refers to humans’ perception of exerting control over actions and the environment. Although SoA is known to guide human behavior in various domains of daily life, little research so far has addressed the interplay of influencing factors. By the example of digital media usage, this online study aims to investigate the impact of action control (e.g., decisional control), motivational factors (e.g., outcome valence), and traits (e.g., locus of control) on SoA and emotional experience. For this purpose, 99 subjects read an adventure fiction including critical scenarios forcing them to select single courses of action from two possible alternatives. Using a 2x2 mixed design, we manipulated decisional control (between-subjects: low vs. high) and the valence of the predetermined action outcome (within-subjects: positive vs. negative), and recorded participants’ SoA and emotional experience (i.e., competence, frustration, enjoyment). After controlling for locus of control, MANCOVA results revealed a significant interaction of the independent variables on SoA (η_p²= .05) indicating stronger influences of negative outcomes under low decisional control. Generally, greater decisional control benefited SoA (η_p² = .12), though, did not significantly impact emotional experience. Although MANOVA suggested outcome valence to determine both SoA and emotional experience, when adjusted for locus of control, only frustration differed significantly (η_p² = .13) for the two outcome valences with failure inducing higher frustration. These findings demonstrate the relevance of decisional control for maintaining SoA and highlight traits as important determinants for individual emotional responses to action outcomes.
