Linked Outcomes in Various EEG-Hyperscanning Setups

Sponsor: Spaulding Rehabilitation Hospital

Summary

The goal of this observational study is to investigate how brains of healthy controls respond when they interact with their romantic partner compared to when they interact with a stranger. The main goals are: * Explore how two people's brains interact with each other by recording brain activity at the same time (a method called "hyperscanning") using electroencephalography (EEG). Using hyperscanning, this study will compare brain-to-brain communication in romantic couples versus strangers, both when they are together in person and when they are interacting remotely. * Test a computational model that will help explain how this brain-to-brain communication works, using real data from the brain activity EEG recordings. * Explore whether factors such as age, gender, how aware people are of their own body sensations, and their level of attachment influence brain-to-brain communication. Researchers will compare brain-to-brain communication in romantic couples versus strangers, both when they are together in person and when they are interacting remotely to see which factors effect brain-to-brain communication. Enrolled participants will: * Complete a consent visit with their romantic partner where they will sign a consent form and have their pain sensitivity assessed. * Fill out sets of questionnaires assessing their romantic relationship, their personality, and other traits. * Complete two EEG scans, one with their romantic partner and one with a stranger. At both scans they will conduct a pain task, a communication task, and a light stimulation task.
