Outcome processing and the sense of agency

People can distinguish outcomes they cause from those they do not; that is, they are quite able to sense self-agency in outcomes. A well-received idea is that the sense of agency is produced by a comparison between a predicted outcome and the actual outcome that occurs. While research has generally focused on understanding predictive representations and the comparison process, less work has been done on the actual outcomes and, in particular, how these are perceived or apprehended. Here, we studied this issue. In two experiments, we found outcomes are continuously, as opposed to partially, sampled throughout their span. Specifically, we found that prediction-inconsistent signals embedded within otherwise prediction-consistent outcomes were able to influence agency ratings, and this was true whether the contrary signals were embedded early or late in the outcome.
