Children with developmental dyslexia (DD) may differ from typical readers in aspects other than reading. The notion of a general deficit in the ability to acquire and retain procedural ("how to") knowledge as long-term procedural memory has been proposed. Here, we compared the ability of elementary school children, with and without…

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…

In three experiments, sighted college students tried to learn the names of the first 10 symbols of the braille alphabet. In Experiments 1 and 2, visual examination of the symbols enhanced learning. In Experiment 3, similar results were obtained when standard size braille symbols were used during the study trials. (Author)

This study evaluated performance of blind (n=17) and sighted adults on a haptic numerosity task of braille symbols in which symbol size was varied. Although blind subjects performed better than seeing subjects, the rate of learning and patterns of errors were similar, except that blind subjects did better with standard than with enlarged symbols.…

Two experiments were conducted with 80 college students to examine factors associated with the crossmodal facilitation of learning Braille symbols when the visual modality is utilized. In Experiment 1 subjects using the haptic mode were informed of both the structure of the braille cell and the range of dot numerosity of the symbols to be…

The paper reports on a study of Braille learning in which subjects (N=96) were provided with information about the structure of the Braille alphabet and expressly instructed to use that information during learning. A previous experiment had found that merely providing subjects with information about Braille alphabet structure had no effect on…

Seventy-two sighted college students who studied the braille or Fishburne alphabet for eight minutes were tested for recall. More Fishburne than braille items were recalled, independent of item arrangement. Results suggest that visually impaired persons might use the Fishburne system for labelling personal objects or when braille learning is too…

The study examined modality effects in the learning of Braille through providing a variety of either study or test trials in either the visual or haptic modalities. Subjects were 144 right handed college students. Results supported previous experiments demonstrating the visual modality superior to the combined visual-haptic or the haptic modality…

Two experiments, each involving 96 sighted undergraduates, investigated the effects on braille learning of presenting information about the number of dots a symbol contains at the beginning of the study interval (prompting condition). In study 1, prompting was compared with presenting no information during the study interval. In experiment 2,…

Two studies examined the effects of handedness on braille learning. Experiment 1 featured 64 sighted undergraduates at North Carolina State University, all of whom were right-handed and had no experience with braille. Results revealed that females outperformed males, but that, contrary to expectation, no significant effects of handedness were…
