Finding the neural correlates of collaboration using a three-person fMRI hyperscanning paradigm

Description: The collaborative 3-person Pictionary task is a multi-player version of the Pictionary game [1]. The goal of the task is to draw a verb independently and collectively for others to guess. Nine verbs were drawn over three runs. The drawing of each verb can be split into three phases: independent phase (two blocks), evaluation phase (one block), and the collaboration phase (three blocks). Each block lasted for 30s, and was separated by a fixation period jittering around 7-8s. Ref[1]: Xie, Hua, et al.
