摘要：The present study attempted to investigate stimulus equivalence formation by participants with Down’s syndrome. Participants learned auditory-visual conditional discriminations with pseudo-words and was manipulated the stimulus similarity in two experimental conditions. The stimuli had multiple differences between them in the first condition, and had critical differences between them in the second condition. Four individuals with Down’s syndrome participated. Relations between dictated words and pictures and between dictated and printed words were trained through matching to sample procedures. Two participants also learned responses of constructing the words by the ordinal selection of their elements. Performances tested were naming of printed words and pictures, and matching printed words to pictures and pictures to printed words. Results suggested that three of the four participants formed equivalence classes in both experimental conditions, whereas the other participant showed signs of class formation only in the first experimental condition. Two participants had more difficulties with training and testing in the second condition. The difficulties were attributed to restricted stimulus control. Key words: stimulus equivalence, reading, stimulus similarity, stimulus control, Down’s syndrome
