Participants will undergo either right prismatic adaptation or right virtual prism adaptation, along with cognitive and motor assessments.

Participants will undergo either left prismatic adaptation or left virtual prism adaptation, along with cognitive and motor assessments.

Participants will undergo neutral prism adaptation or neutral virtual prism adaptation, along with cognitive and motor assessments.

Participants will fit with prismatic goggles that deviate their visual field by 13° either leftward or rightward. They will seat in front of a white horizontal board on which three target dots (5 mm diameter) were positioned at 0, -10 and +10° from their body midline at a distance of 57 cm from their eyes. They will perform a total of 150 verbally instructed pointing movements with their right index finger towards the right (+10°) and left (-10°) targets in a pseudorandom order.

Better performance in tests that evaluate visuospatial skills like line bisection test. The minimun value is 0 and the maximum is 3. Higher scores mean a worse outcome

improvement in tests evaluating alexithymia such as TAS-20. The TAS 20 has scores that have a minimum of 20 and a maximum of 100. Scores greater than or equal to 61indicate high levels of alexithymia

investigate the brain areas involved in the tasks with High Density Electroencephalography (EEG HD) and functional near infrared spectroscopy (fNIRS). The most active areas will be listed in a table

Promote rewarding experiences that improve self-esteem, the perceived sense of self-efficacy, the quality of life measured with the Parkinson's disease questionnaire (PDQ-39).The minimum score is 0 which indicates the best quality of life A maximum score is 100 which indicates the worst quality of life.
