Reviews a study which investigated children's predictions and explanations of the formation of images through pinholes by use of extended light sources. Interviews with 9- to 13-year-old children at a science center revealed that a prevalent model for image formation involved light that traveled from the sources as a whole. (ML)

The studies found that in processing words partially sighted children, like fully sighted children, used both lexical and nonlexical processing, though perhaps in difference balance. Recognition and…
