“…Equivalence classes may not only be established by teaching common names to dissimilar stimuli (common bidirectional naming, C‐BiN), but also by teaching intraverbal relations among them (intraverbal bidirectional naming, I‐BiN). When stimuli are linked together through intraverbal training, such as “Cardinal goes with Virginia”, and “Virginia goes with dogwood,” participants may learn to treat them as members of the same equivalence class, as measured by both selection (i.e., MTS) and vocal (i.e., intraverbal) tests (e.g., Ma, Miguel, & Jennings, ; Petursdottir, Carp, Peterson, & Lepper, ; Santos, Ma, & Miguel, ). Thus, during MTS tests, participants may tact the sample (e.g., saying, “Dogwood”), the product of which would evoke an intraverbal (“Dogwood goes with Virginia.”), whose product would serve as a discriminative stimulus (S D ) for the selection of the correct comparison.…”
