Are you 55 years of age or older and/or have a diagnosis of Parkinson disease? We are doing a research study to learn more about vision and attention while walking for people with and without Parkinson disease. If you can walk longer than 2 minutes at a time without assistance or an assistive device, you may be able to take part. Help us learn how the ability to start walking changes with different amounts of visual input and attention.

Do you ever notice that you feel more energized or alert when meeting new people and forming first impressions? Other times, a first meeting will rub you the wrong way and you may feel less attentive. If you've experienced one or both of these, you may wonder: What makes a good first impression? How do you know you want to become friends with someone? What information do we pay attention to when interacting with someone for the first time? Good questions! Neuroscience and psychology researchers wonder about the same things. Here at the Social Neuroscience and Health lab, we study how the brain and the immune system work together to influence our behaviors and experiences. The Friendship Pathways Study is a research project aiming to answer questions about how the brain and immune system communicate when meeting new people and forming friendships.
