“…This strategy has been shown to lead to the development of classes whose members share the same function (e.g., Dougher, Augustson, Markham, Greenway, & Wulfert, ; Griffith, Ramos, Hill, & Miguel, ; Lillie & Tiger, ; Saunders, Drake, & Spradlin, ; Sidman & Tailby, ). In RFT, the establishment of relational frames and the genesis of derived behavior is typically examined via an arranged history of multiple exemplar training (MET; e.g., Baltruschat et al, ; Baltruschat et al, ; Berens & Hayes, ; Gould, Tarbox, O'Hora, Noone, & Bergstrom, ; Luciano, Becerra, & Valverde, ; Najdowski, Bergstrom, Tarbox, & St. Clair, ; Najdowski, St. Clair, Fullen, Child, Persicke, & Tarbox, ; Persicke, Tarbox, Ranick, & St. Clair, ; Sivaraman, ; Tarbox, Zuckerman, Bishop, Olive, & O'Hora, ). Thus, multiple exemplar training is utilized within both the stimulus equivalence and RFT approaches.…”
