Metacognition of different parameters of movement:

In this project, I want to understand what kind of information is available for the monitoring of voluntary arm movements, and whether this monitoring ability is domain-specific or domain-general. To measure motor metacognition, I use the "Skittles" task as a paradigm. On each trial, participants throw a ball, and afterwards they 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. The 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 manipulandum used to control the ball also allows us to record the movements and then display them in a fully visual way.

Metacognition and motor disorders:
Another project I’m working on aims to investigate how movement impairment affects motor metacognition. There are a number of motor disorders that affect voluntary movement. I decided to start with Parkinson’s disorder (PD) patients, as some previous studies suggest metacognitive deficits in these patients. I plan to compare metacognition of PD patients to metacognition of matched controls without PD across motor, visual and memory domains. I use The Skittles task as the motor task.
