Viewing videos of different Social Relationship interactions: fNIRS and Social Relationship Data

In this study, participants were shown three video clips depicting a male-female pair either eating, exercising or baking together. Prior to the onset of each video, participants were told whether the pair of actors were friends, siblings or romantic partners. Keeping the order of the video clips constant, and changing only the labels of each video, prefrontal cortex activity was measured using fNIRS.
