The illusion of control refers to the phenomenon of feeling in control over an outcome that is not caused by our action. It shows, for instance, in the outcome density bias (ODB): Participants often judge that they have more control over non-contingent action outcomes when the overall frequency of outcomes is high rather than low, for example when winning frequently rather than rarely in gambling. It has been shown that desirability of an outcome is positively associated with control ratings and the ODB. In the contingency learning paradigm by Alloy and Abramson (1979), the impact of desirability of outcomes on the ODB has exclusively been demonstrated by adding/ subtracting points associated with monetary, extrinsic reinforcement (e.g. Alloy & Abramson, 1979, Exp. 2). In our study we systematically varied and combined (a) intrinsic valence of outcomes (positive valence: jumping over a precipice; negative valence: falling into a precipice) and b) extrinsic reinforcement (gaining/ losing points) in an online gamified version of a contingency learning task in which there was no contingency between actions and outcomes. Preliminary results show an increase in perceived control with the introduction of reinforcement, especially in the negative valence in which the aim was to prevent falling into the abyss and losing points.
