Children and adults were trained and tested on formation of novel simple discriminations and conditional stimulus relations. Subjects who formed these sets were trained and tested on formation of stimulus equivalence classes. A modest majority of children matched directly paired stimuli; a few matched indirectly paired stimuli. All normal adults…

Trained preschoolers and adults on three sets of successive discriminations with stimuli labeled A, B, and R. Tested for derived stimulus-response relations and stimulus-stimulus relations. Adults displayed class-consistent B-R and A-B performances over all conditions. Children's display of class-consistent B-R performance varied by training…

We examined some conditions under which a response acquired as a tact might facilitate the establishment of a mand. We taught 3 participants with developmental disabilities to tact the items ranked highest and lowest in a preference assessment and subsequently tested to see if the responses occurred as mands. All participants manded for the highly…
