Neuroimaging studies using backward masking suggest that conscious and nonconscious responses to complex signals of fear (facial expressions) occur via parallel cortical and subcortical circuits. Little is known, however, about the temporal differentiation of these responses. Psychophysics procedures were first used to determine objective thresholds for… (More)

Behavioral studies have shown that, at a population level, women perform better on tests of social cognition and empathy than men. Furthermore Autism Spectrum Disorders (ASDs), which are characterized by impairments in social functioning and empathy, occur more commonly in males than females. These findings have led to the hypothesis that differences in the… (More)
We describe a patient (JS) with impaired recognition and distorted visual perception of faces after an ischemic stroke. Strikingly, JS reports that the faces of family members look distorted, while faces of other people look normal. After neurological and neuropsychological examination, we assessed response accuracy, response times, and skin conductance… (More)

Sun moths (Castniidae) constitute a family of day-flying moths that due to their slim bodies, broad and often richly coloured wings and clubbed antennae closely resemble butterflies. However, despite this superficial similarity, sun moths are not related to butterflies but belong to the diverse cossoid assemblage of lepidopterous families (Edwards et al.… (More)
The ability to recognize facial expressions of basic emotions is often considered a universal human ability. However, recent studies have suggested that the commonality of recognition mechanisms across cultures has been overestimated and that people from different cultures (Western and Chinese) use information from different regions of face to internally… (More)
