Abstract
Preschoolers who explore objects haptically often fail to recognize those objects in subsequent visual tests. This suggests that children may represent qualitatively different information in vision and haptics, and/or that children's haptic perception may be poor. Seventy-two children from 2 ½ to 5 years and 20 adults explored unfamiliar objects either haptically or visually, then chose a visual match from among three test objects, each matching the exemplar on one perceptual dimension. All age groups chose shape-based matches after visual exploration. Five-year-olds and adults also chose shape-based matches after haptic exploration, but younger children did not match consistently in this condition. Certain hand movements performed by children during haptic exploration reliably predicted shape-based matches but occurred at very low frequencies. Thus, younger children's difficulties with haptics-to-vision information transfer appeared to stem from their failure to use their hands to obtain reliable haptic information about objects.
