Influence of Emotions on Decision-making in Parkinson's Disease

Some research shows that positive emotional states are associated with greater self-confidence, greater optimism, and better regulation of our decision-making. The goal is to test whether positive emotional induction could improve decision-making in Parkinson's disease.

Listening to music would decrease anxiety levels and increase self-esteem levels. Who says Parkinson says dopamine deficiency and so the investigators can think that the investigators can help patients by inducing a positive emotion through musical stimulation.

All participants will be subject to emotional induction. They will be divided into two different conditions: either they will be induced in a positive state, or they will be maintained in a neutral state. For this, video clips (positive or neutral) containing music will be presented. Immediately after the presentation of the video, participants will have to perform the Iowa Gambling Task test. This is a sequential task to evaluate decision-making capabilities.
