A Role For Contrast Gain Control In Skin Appearance, Richard Russell, Carlota Batres, Alex L. Jones, Aurélie Porcheron
A Role For Contrast Gain Control In Skin Appearance, Richard Russell, Carlota Batres, Alex L. Jones, Aurélie Porcheron
Psychology Faculty Publications
Apparent contrast can be suppressed or enhanced when presented within surrounding images. This contextual modulation is typically accounted for with models of contrast gain control. Similarly, the appearance of one part of a face is affected by the appearance of the other parts of the face. These influences are typically accounted for with models of face-specific holistic processing. Here we report evidence that facial skin appearance is modulated by adjacent surfaces. In four experiments we measured the appearance of skin evenness and wrinkles in images with increased or decreased contrast between facial skin and adjacent image regions. Increased contrast with …

Examining The ‘Cosmetics Placebo Effect’, Carlota Batres, Sarah S. Kramer, Caroline G. Deangelis, Richard Russell

Previous studies have found a positive effect of cosmetics on certain behavioral measures, such as the tip given to waitresses by male patrons. These studies have employed confederates who usually wear cosmetics. We therefore sought to examine whether the positive effect found in these studies could, in part, be explained by a change in behavior. In order to test the possibility of a ‘cosmetics placebo effect’, we employed a confederate to solicit donations from passersby. On some days our confederate would not have any cosmetics applied to her face (i.e., no cosmetics condition), on some days cosmetics were pretended to …
Makeup Changes The Apparent Size Of Facial Features, Alex L. Jones, Aurélie Porcheron, Richard Russell
Makeup Changes The Apparent Size Of Facial Features, Alex L. Jones, Aurélie Porcheron, Richard Russell
Psychology Faculty Publications
Makeup is a prominent example of the universal human practice of personal decoration. Many studies have shown that makeup makes the face appear more beautiful, but the visual cues mediating this effect are not well understood. A widespread belief holds that makeup makes the facial features appear larger. We tested this hypothesis using a novel reference comparison paradigm, in which carefully controlled photographs of faces with and without makeup were compared with an average reference face. Participants compared the relative size of specific features (eyebrows, eyes, nose, mouth) of the reference face and individual faces with or without makeup. Across …
Is Pigmentation Important For Face Recognition? Evidence From Contrast Negation, Richard Russell, Pawan Sinha, Irving Biederman, Marissa Nederhouser
Is Pigmentation Important For Face Recognition? Evidence From Contrast Negation, Richard Russell, Pawan Sinha, Irving Biederman, Marissa Nederhouser

It is extraordinarily difficult to recognize a face in an image with negated contrast, as in a photographic negative. The variation among faces can be partitioned into two general sources: (a) shape and (b) surface reflectance, here termed 'pigmentation'. To determine whether negation differentially affects the processing of shape or pigmentation, we made two sets of faces where the individual faces differed only in shape in one set and only in pigmentation in the other. Surprisingly, matching performance was significantly impaired by contrast negation only when the faces varied in pigmentation. This provides evidence that the perception of pigmentation, not …
