Abstract
We taught three children with visual impairments to make tactual 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 were to select the matching stimulus from an array of three comparisons. In order to minimize participant errors, we arranged braille characters into training sets in which the target and non-target stimuli in the comparison arrays were initially maximally different in terms of the number of dots comprising each character. As participants mastered these discriminations, we then increased the similarity between target and non-target comparisons (i.e., an approximation of stimulus fading). All three participants’ accuracy systematically increased following the introduction of this procedure.
