Abstract	The paper reports on two experiments in Braille learning which compared blind and sighted subjects on the immediate recall of haptically-examined Braille symbols. In the first study, sighted subjects (N=64) haptically examined each of a set of Braille symbols with their preferred or nonpreferred hand and immediately recalled the symbol by drawing it or calling out the number of each dot present. Neither the effect of hand used, response type, nor their interaction were significant. In the second study each of 16 subjects (all of whom were legally blind) examined the symbols with the preferred hand and orally reported the number of each dot present. Comparison with the previous experiment found a high degree of similarity between the two groups in number correct, type of error, and relationship between item difficulty and number of dots. Findings indicate the same processes are operative in this task performance for both blind and sighted persons suggesting that research in perceptual, learning, and memory tasks with sighted subjects may be applicable to the visually impaired.
