Here, we examined how these functions reflect PPC activity during natural viewing. Fourteen healthy volunteers watched a re\u2010edited movie during functional magnetic resonance imaging (fMRI). Participants separately annotated behavioral priority (accounting for percepts, thoughts, and emotions) they had experienced during movie episodes. Movements in the movie were quantified with computer vision and eye movements were recorded from a separate group of subjects. Our results show that while overlapping dorsomedial PPC areas respond to episodes with multiple types of stimulus content, ventrolateral PPC areas exhibit enhanced activity when viewing goal\u2010directed human hand actions. Furthermore, PPC activity related to viewing goal\u2010directed human hand actions was more accurately explained by behavioral priority than by movements of the stimulus or eye movements. Taken together, our results suggest that PPC participates in perception of goal\u2010directed human hand actions, supporting the view that PPC has a special role in providing visual signals for the motor system (\u201chow\u201d), in addition to processing visual spatial movements (\u201cwhere\u201d). <jats:italic>Hum Brain Mapp 35:4767\u20134776, 2014<\/jats:italic>. \u00a9 <jats:bold>2014 Wiley
