Not only that... Their measurement of the sense of agency (SoA) is weird. Within the same paper they're inventing a new way to estimate moment to moment SoA and correlating it to reported SoA. Whether their modeling is valid should have been a separate paper. There's a very good chance their experimental design and measurement strategy are influenced by one another.
