This study is looking at how people with Parkinson's disease (a brain disorder that affects movement) learn and produce speech. Researchers want to understand the connection between difficulties with talking and difficulties with understanding speech. You would participate in behavioral tasks involving sound intensity and spoken rate. This includes pairing sentences to colored squares and identifying if sentences have the same or different sound intensity or spoken rate. The study aims to see if these learning challenges can predict differences in how people speak. To join, you need to have Parkinson's disease, be a native North American English speaker, use a drug that includes levodopa, and live in the United States. The study is looking for 50 participants, but its current status is unclear.
