What is vision's role in driving early word production? To answer this, we assessed parent-report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7-57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N =…

Young infants perceive an object's trajectory as continuous across occlusion provided the temporal or spatial gap in perception is small. In 3 experiments involving 72 participants the authors investigated the effects of different forms of auditory information on 4-month-olds' perception of trajectory continuity. Provision of dynamic auditory…

Dr. Orfield's highly readable guide on vision development presents ground-breaking solutions to common learning problems and is supported by substantial data. This holistic common sense--that most people do not know--is not just about vision but also how vision is interrelated with learning. It teaches how to care for a child's vision as well as…

Evidence suggests that visual processing is divided into the dorsal ("how") and ventral ("what") streams. We examined the normal development of these streams and their breakdown under neurological deficit by comparing performance of normally developing children and Williams syndrome individuals on two tasks: a visually guided action ("how") task,…

One reason students give for attending a community college is that the mathematics requirements appear to be less rigorous. Many of the author's students have told her that they have chosen to seek an associate's degree first because they do not feel confident that they could successfully complete the mathematics requirement at a four-year…
