This study evaluated performance of blind (n=17) and sighted adults on a haptic numerosity task of braille symbols in which symbol size was varied. Although blind subjects performed better than seeing subjects, the rate of learning and patterns of errors were similar, except that blind subjects did better with standard than with enlarged symbols.…

Evaluated the effects of stimulus complexity and rule usage on a visual perspective-taking task administered to preschoolers, first, third, and fifth graders, and adults. Errors decreased with age, and more errors occurred with the more complex visual arrays. Very young children could not reliably match a photograph to a physical array. (Author/RH)
