Robust natural depth for anticorrelated random dot stereogram for edge stimuli, but minimal reversed depth for embedded circular stimuli, irrespective of eccentricity by Hibbard, Paul B, Asher, Jordi M

“…The small differences between the images formed in our left and right eyes are an important cue to the three-dimensional structure of scenes. These disparities…”

Contrast normalisation masks natural expression-related differences and artificially enhances the perceived salience of fear expressions by Webb, Abigail L.M, Hibbard, Paul B, O'Gorman, Rick, Li, Zezhi

“…Fearful facial expressions tend to be more salient than other expressions. This threat bias is to some extent driven by simple low-level image properties,…”
