Effects Of Caro On Stimulus Equivalence: A Systematic Replication, Abdulrazaq Imam, J. V. Blanche

The first experiment was a systematic replication of Duarte, Eikeseth, Rosales- Ruiz, and Baer (1998), in which participants in a CARO group and a No- CARO group performed conditional discrimination tasks with stimuli using a paper- and- pencil format for training and testing of equivalence relations. The presence of the CARO led to the nonemergence of equivalence classes. In the second experiment, participants performed conditional discrimination tasks using standard matching- to- sample training and testing procedures on a computer with …
