Since its introduction, Continuous Flash Suppression has been extensively used as a window into preconscious visual processing (Stein, Hebart & Sterzer (2011) . Breaking continuous flash suppression: A new measure of unconscious processing during interocular suppression? Frontiers in Human Neuroscience, 5, 167). We too, have recently taken this approach to ask whether evaluation of faces on social dimensions of trust and dominance is restricted to conscious appraisal or, rather happen at a preconscious level. We will present data showing that by capitalizing on the individual differences between observers in the time they take to overcome suppression by CFS, it is possible to identify a number of observer-specific personality traits as well as markers of local brain structure that are instructive in helping us understand the neural basis of social evaluation of faces.
