The use of conditional discrimination abilities and procedures is fundamental to the equivalence literature, (e.
The widespread use of conditional discriminations in testing an individual's ability to form equivalence relations (e.
Equivalence relations are said to occur when a set of arbitrary conditional discriminations is trained and, as a consequence, a new set of untrained conditional relations emerges--specifically, reflexivity, symmetry, and transitivity relations (Sidman & Tailby, 1982).
This raises the issue of whether the emergence of equivalence relations is possible from the exclusive training of positive conditional relations.
In most studies of equivalence class formation, training and testing were conducted on an individual basis and with small numbers of participants per study.
