Summary
The purpose of this study is to investigate if individuals with a cannabis use disorder have an impaired cerebellar function by assessing possible alterations to their implicit adaptation during a visuomotor rotation task.
Conditions
Interventions
| Type | Name | Description |
|---|---|---|
| BEHAVIORAL | Visuo-motor rotation | Participant moves a cursor on a screen by sliding a pen over a digital tablet. Participants perform a center-out movement, aiming to a target that appears over one of a set of eight markers radially distributed. In several block of trials, the mapping of the pen position to the cursor is rotated. |
| BEHAVIORAL | Explicit strategy | Participant is provided with an explicit instruction as to how counteract the effects of the visuo-motor rotation via aiming to a marker adjacent target |
