Abstract and Keywords
This article reviews how behavioral methods, event-related potentials (ERPs), and functional magnetic resonance imaging (fMRI) are used to understand the acquisition of perceptual expertise in both adult and developmental populations. The purpose of this study is to provide an overview of the research focused on understanding the role and nature of experience in both the acquisition of perceptual expertise and the development of expert face processing. Behavioral tasks designed to assess perceptual expertise in adults include: perceptual discrimination and matching tasks and the categorization and recognition memory tasks. Training studies are used to mimic the natural acquisition of face and non-face perceptual expertise. Using these various methods and techniques, studies of perceptual expertise prove useful to the understanding of specialization of perceptual skills and categorization abilities and expands our understanding of the function and plasticity of the visual system.
