Main Effect: brain regions that activated transiently upon presentation of unexpected human-like characters, irrespective of whether these were attention grabbing or non-attention grabbing. A_time: regions where the transient BOLD response for the attention grabbing characters covaried positively with the characters' processing times. A_ampl: regions where the transient BOLD response for the attention grabbing characters covaried negatively with the amplitude of the gaze shift. p values are corrected for multiple comparisons at the whole-brain level (except for t values reported in italics), and k is the number of voxels in each cluster. Overt/Covert, spatial orienting with eye movements allowed/disallowed; MT-complex, middle temporal complex (V5+/MT+); TPJ, temporo-parietal junction; pMTG, posterior middle temporal gyrus; FEF, frontal eye fields; MFG, middle frontal gyrus; IFG, inferior frontal gyrus; IFS, inferior frontal sulcus.
