Conditions: narrative film shown continuously. Method (as reported): re-analysis of behavioural segmentation data (Study 1a, 41 participants; 1b, 24 participants) and fMRI data from viewers of The Red Balloon (33 minutes); edits coded as continuous in space/time/action, discontinuous in space or time but continuous in action, or discontinuous in action too. Result: discontinuities in action had the biggest impact on where viewers marked event boundaries; space and time discontinuities had minor effects; edits produced large transient responses in early visual areas, with different patterns for spatial-temporal vs action changes.
