Description: In this project, we want to understand what kind of information is available to monitoring of voluntary arm movements, and whether this monitoring ability is domain-specific or domain-general. To measure motor metacognition, we use Skittles task as a paradigm. This task simulates ball throwing. Each trial is a ball throw, after which participants have to judge their movement based on different information, for example, based on a higher-lever, more indirect parameter (trajectory) or based on a lower-level, more direct parameter (angle of the arm during the throw). After a binary decision about their movement, participants report their confidence level about this decision. Combination of these responses allows us to quantify metacognition. The virtual environment allows us to control the visual information that participants see. For example, we can hide the ball after the throw is made. A bespoke-made manipulandum used to control the ball also allows us to record the movements and then display them in a fully visual way.
