Face recognition is crucial for social interaction and development and undergoes a prolonged maturation until the teens. However, little is known about the maturation of the normal psychological or neural processes that support the development of face perception in children. The goal of this proposal is to use cutting-edge psychophysical and neuroscience methods to elucidate the development of psychological processes involved in face recognition, the underlying neural systems, and their link. These results are expected to address wide gaps in the understanding of normal visual development, add significant knowledge to theories of face perception and object representation, and provide an essential base for future research on developmental disorders and pediatric imaging in general. Such a rigorous and convergent approach in elucidating normal development is crucial for understanding the many developmental disorders that involve deficits in visual or face processing such as Williams syndrome and autism.
