Videos were extracted from 5 females expressing dynamically happiness (HA), anger (AN) or neutral (NE), matched for luminance, contrast, size (3°x3°). They started with a neutral expression (100ms), followed by emotional progression until paroxysm (1000ms), and dynamical maintenance at the peak level (100ms). Snapshots were extracted from each movie at t =0ms for the neutral expression condition, and t =1100ms for the emotional paroxysm condition. Flankers were created by blending 2 non emotional faces and 4 objects, resulting in 2°x2° non informative patterns (luminance 40% higher than that of the faces). Targets were 3°x3° Chinese pictographs, without repetition for a single subject.
