Free Wally: Where motor intentions meet reason and consequence

Publication date: Available online 5 August 2019Source: NeuropsychologiaAuthor(s): Ceci Verbaarschot, Jason Farquhar, Pim HaselagerAbstractTo investigate the neural preparation and awareness of an intention to act, neuroscientists typically examine spontaneous movements: self-paced flexions of the hand or foot. However, these movements may not present a straightforward case of intended action as they are performed in absence of reasons to act and without the evaluation of action consequences. Therefore, a common criticism of these studies is that they lack ecological validity, because the results do not generalize to the more societally relevant deliberate actions that we perform in daily life. We agree that research on intended action should include reason-based deliberate actions in order to be more relevant for debates about human agency and free will. Therefore, we have developed a computer game called “Free Wally”, which invites players to perform deliberate actions to achieve a goal. Free Wally provides a controlled environment for studying deliberate intended action, by presenting information for deciding whether or not to act, what action to perform and when to perform it, incorporating all basic components of an ecologically valid intended act. As a first step to validate our setup, we compare this game to a second computer game that measures spontaneous actions in a traditional way. While playing either game, the timing of the experienced intentions to act is me...
