Spatial Coding in Normal, Autistic and Blind Children

The experiment tested whether tactile stimulation would be coded in terms of visual location, even when no visual cues were available. 10 blind, 10 blindfolded, and 10 sighted normal as well as 10 sighted autistic children, were tested, and the results did not indicate that space is represented solely in visual terms. The findings suggested that all groups used such information as was most readily available from the incoming sensory data rather than internally represented schemata of visually organized space.
