Individual Brain Charting: HCP Social task

This dataset contains functional magnetic resonance images (fMRIs) of 12 subjects performing HCP Social task that intended to provide evidence for brain activity related to social cognition. The paradigm included two categories of blocks, in which movies were presented during short epochs. The movies consisted in triangle-shape clip art, moving in a predetermined fashion. Putative social interactions could be inferred from movements in the so-called social condition. In contrast, objects appeared to be randomly moving in the random condition. The task was constituted by ten blocks per run, five for each category, whose order was pseudo-randomized for every run, but fixed for all participants. There was only one trial per block. It consisted of a twenty-second period of video-clip presentation plus three seconds maximum of a response period, indicated by a momentary instruction on the screen. Thus, the total duration of a block was approximately twenty three seconds. A fixation-cross period of fifteen seconds was always displayed between blocks.
