A comparison of backward masking of faces in expression and gender identification

The effects of different masking conditions on identification of face gender and expression at different target durations (17-119 ms time range) were studied in two experiments. In Experiments 1a and 1b, the effects of face masks were compared against those of noise masks (scrambled face stimuli) an...
