I would suggest that the blind children are substituting felt-sense for sight. Touch and sound are the only "cognitive" technique that is open to them for relating to the world. Blind children are limited to and responsive to the touch and sounds of their care givers. Therefore this is how they learn to relate to the world. I believe this study demonstrates certain inherent capacities in the developing child. Why and how a blind child, without any training, would point up, when asked to look up, give credence to their capacity for substitution and a yet undefined ability; intrinsically printed in their brain. Why and how a blind child would merely touch a table, when ask to only touch a table, and then proceed to explore the table with their hands, when asked to look at, is consistent with my stated explanation. In short, there appears to be a matrix in the developing brain of young children, blind or sighted, that, through healthy nurturing will, of necessity, be expressed. As well, neurological substitution and adaptation is a well established fact in various disabilities. I offer this for your consideration.
