Can blindsight be superior to 'sighted-sight'?
DB, the first blindsight case to be tested extensively (Weiskrantz, 1986) has demonstrated the ability to detect and discriminate a range of visual stimuli presented within his perimetrically blind visual field defect. In a temporal two alternative forced choice (2AFC) detection experiment we have investigated the limits of DB's detection ability within his field defect. Blind field performance...
متن کاملFrom blindsight to sight: cognitive rehabilitation of visual field defects.
PURPOSE Traditionally, post-chiasmatic lesions were believed to result in complete and permanent visual loss in the topographically related areas of the visual field. However, a number of studies with monkeys, and later with humans, have demonstrated spared implicit visual functioning, referred to as 'blindsight'. The present study assessed whether training this phenomenon would induce an objec...
متن کاملSuperior intelligence in sighted retinoblastoma patients and their families.
There are many well-known genetically determined disorders associated with low intelligence, but at least 2 conditions have been reported associated with superior intelligence: retinoblastoma (Thurrell and Josephson, 1966; William, 1968) and the autosomal recessive form of torsion dystonia (Flatau and Sterling, 1911; Eldridge et al, 1970). Although proof is still lacking, the superior intellige...

important for screening purposes, but have to be combined with detailed biochemical and functional studies. In fact, the experience with yeast showed that the many possibilities offered by genomics and proteomics shifted the emphasis from cloning back to biochemistry and thus gave us more time for functional studies. What is the biggest hindrance to science? Administrators who like paragraphs m...
متن کاملBraille in the Sighted: Teaching Tactile Reading to Sighted Adults
Blind people are known to have superior perceptual abilities in their remaining senses. Several studies suggest that these enhancements are dependent on the specific experience of blind individuals, who use those remaining senses more than sighted subjects. In line with this view, sighted subjects, when trained, are able to significantly progress in relatively simple tactile tasks. However, the...
