I am broadly interested in the cognitive mechanisms involved in visual object recognition and categorization, and how these processes are modulated by experience and expertise. Most of my research has used faces – a category with which we are all experts – to study one behavioral marker of perceptual expertise, holistic processing. Previous work in this area has focused on determining whether holistic processing arises due to a holistic representation or an automatized perceptual strategy, the time course of holistic processing, and how holistic processing is affected by stimulus manipulations such as spatial frequency content and inversion. New projects are aimed at studying individual differences in holistic processing, and how these relate to face recognition performance and more general individuation learning abilities.
