Population: Children aged 7-15 years

This study examines how visual language experience can impact visual linguistic perception and reading span now in the growing reading child (ages 7-9, and 13-15 years). We test the hypothesis that early exposure to ASL, and/or knowledge of visual sign phonology, may cause a larger perceptual span, having an impact on reading capacity. The three studies are further united in their use of eyetracking technology, which has the potential to provide new assessment tools for the study of young infants and children.
