The transformation of consequential functions in accordance with the relational frames of more-than and less-than

Across three experiments, the transformation of consequential functions in accordance with a seven-member relational network (A-B-C-D-E-F-G) was investigated. In this network, the relational rankings ranged from A, ranked the least, to G, ranked the most. In the first phase, contextual cues for more-than and less-than were established by training participants across multiple exemplars to select comparisons containing larger quantities in the presence of the former cue, and fewer quantities in the presence of the latter cue. Participants then were trained in six conditional discriminations (i.e., AD, F>E, and G>F) with the contextual cues as samples and nonsense words as comparisons, and all possible derived relations were tested (e.g., B
