In this experiment, we are particularly interested in the effects of motor imagery when we have been watching someone else perform a task. We are interested in whether or not motor imagery might provide us with an idea of our own abilities of the action. While everyone between the ages of 18-60 years old are welcome to participate, we are particularly interested in individuals who cannot generate (imagine) visual images in the ‘mind’s eye’. This is often referred to as Aphantasia.

In this experiment, you will be asked to watch videos of someone else performing an action. After each video, you will be asked to rate how confident you feel in being able to perform the same action. Sometimes, you may also be asked to imagine performing the movement before making the rating. These procedures will take about 15-20 minutes, with 5 minutes of instructions and task-familiarization. These procedures will be completed online via Gorilla Experiment Builder. Prior to completing this task, you will be asked to complete a number of questionnaires. These procedures will take about 5-10 minutes. These questionnaires will be completed online via Qualtrics. The total time to complete the experiment is approximately 30-40 minutes.

If you would like to participate and get more information please contact Dr. Matthew Scott; kin.msl@ubc.ca. Please write "onlineJuggling" in the subject heading. The principal investigator for this project is Dr. Nicola Hodges.
