Monocular-contingent and binocular-contingent aftereffects

Texture contrast aftereffects are monocular; texture density aftereffects are binocular

Two experiments examined interocular transfer for simple and dynamic aftereffects of density and contrast. Simple aftereffects of texture contrast were shown to be primarily monocular. Texture density aftereffects were shown to be primarily binocular. Similarly, dynamic aftereffects to repeated changes in contrast were found to be completely monocular; those to repeated changes in density were ...

Local and global factors in spatially- contingent coloured aftereffects

Dodwell and O'Shea's [(1987) Vision Research, 27, 569-580] conclusions that contingent coloured aftereffects (CAEs) depend on gobal pattern organization were investigated in four experiments. In Expt 1, we replicated findings that CAEs can be induced with complex patterns (concentric circles; radial spokes) under conditions of systematic eye movements. Contrary to Dodwell and O'Shea's argument ...

Orientation-Contingent Face Aftereffects and Implications for Face-Coding Mechanisms

Humans have an impressive ability to discriminate between faces despite their similarity as visual patterns. This expertise relies on configural coding of spatial relations between face features and/or holistic coding of overall facial structure. These expert face-coding mechanisms appear to be engaged most effectively by upright faces, with inverted faces engaging primarily feature-coding mech...

Absence of Sex-Contingent Gaze Direction Aftereffects Suggests a Limit to Contingencies in Face Aftereffects

Face aftereffects (e.g., expression aftereffects) can be simultaneously induced in opposite directions for different face categories (e.g., male and female faces). Such aftereffects are typically interpreted as indicating that distinct neural populations code the categories on which adaptation is contingent, e.g., male and female faces. Moreover, they suggest that these distinct populations sel...
