The study aims to explore how people with Parkinson's disease, a brain disorder that affects movement, understand social cues. This is important because it can affect their quality of life and relationships. Social cognition refers to how we interpret and react to social information, like facial expressions and body movements. The study will use a special brain scan called functional MRI (fMRI) to see how brain activity changes when these patients view social scenes. The study is divided into two parts: first, testing the tasks, and second, using imagery to see brain function. Participants must be aged 30-75, have Parkinson's for at least 3 years, and be under dopaminergic medication (medicines that help with movement problems in Parkinson's).

• Study Duration: 2 stages with functional MRI scans.
• Eligibility: Ages 30-75, diagnosed with Parkinson's, and on dopaminergic medication.
• Considerations: Not suitable for those with specific health devices (e.g., pacemakers) or conditions like claustrophobia.
