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...
متن کاملLocal 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 ...
متن کاملAbsence 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...
متن کاملResponse: Genuine long-term positive aftereffects
lead to positive correlations (Figure 1B). Indeed, because averaging of long stimulus windows reduces the number of statistically independent samples, mathematical considerations predict more positive than negative correlations (see Supplemental Information). Demonstrating a genuine longterm positive aftereffect necessitates statistically comparing empirical correlations with a null distributio...
