Nous
avons enseigné à trois enfants atteints de déficience visuelle à faire
des discriminations tactiles de l'alphabet braille dans un format
de concordance de à l'échantillon. Afin
de minimiser les erreurs des participants, nous avons initialement
disposé des caractères braille dans des ensembles de formation dans
lesquels il y avait une différence maximale dans le nombre de points
dans les stimulus de comparaison cibles et non cibles.

Abstract
We
taught three children with visual impairments to make tactile
discriminations of the braille alphabet within a matching-to-sample
format. That is, we presented participants with a braille character as a
sample stimulus, and they selected the matching stimulus from a
three-comparison array. In order to minimize participant errors, we
initially arranged braille characters into training sets in which there
was a maximum difference in the number of dots comprising the target and
nontarget comparison stimuli. As participants mastered these
discriminations, we increased the similarity between target and
nontarget comparisons (i.e., an approximation of stimulus fading). All
three participants' accuracy systematically increased following the
introduction of this identity-matching procedure.
