Establishing equivalence-equivalence analogical relations via tact and listener training.

We investigated the role of verbal behavior on the emergence of analogy-type responding as measured via equivalence-equivalence relations. In Experiment 1, 8 college students learned to label arbitrary stimuli as, "vek," "zog," and "paf", and in Experiment 2, 8 additional participants learned to select these stimuli when hearing their names in an auditory-visual matching-to-sample (MTS) task.
