The Effect Of Stimulus Choice On A Discrimination Task: Pictures Vs. Objects, Kristen Abbondante

LSU Master's Theses

The effect of the type of stimuli, pictures vs. objects, on discrimination behavior, specifically noun discrimination, was examined with a single-subject multi-element design. A multiple probe across behaviors was used for two participants. The type of stimulus, picture or object, was the alternating treatment. Two autistic children were trained in six noun discrimination tasks utilizing a discrete trial training model counterbalancing the type of stimuli across participants. Generalization of object to pictures and pictures to objects was also examined. Results showed that type of stimuli, picture or object, did not affect treatment. Generalization data was idiosyncratic.
