ESTABLISHING ARBITRARILY APPLICABLE RELATIONS OF
SAME AND OPPOSITE WITH THE RELATIONAL COMPLETION
PROCEDURE: SELECTION-BASED FEEDBACK
Simon Dymond and Tsz Ching Ng
Trinity College Dublin
Research suggests that the relational completion procedure (RCP) is
effective for studying derived relations of same and opposite. Previously,
procedural parameters, such as the presence or absence of a confirmatory
response requirement, were found to have a facilitative effect on the number
of training trials to criterion and overall arbitrary test pass rate (i.e., yield).
These experiments report on the manipulation of additional potentially
important parameters—the presence or absence of selection-based feedback,
4 vs. 8 trial types and of a linked nonarbitrary and arbitrary training phase—
across both the RCP and matching-to-sample (MTS) protocols with either 3
or 5 comparisons. During selection-based feedback, after the production
of the confirmatory response, the sample, contextual cue, and selected
comparison were presented along with corrective feedback. During the linked
nonarbitrary–arbitrary phase, in the presence of the sample stimulus and the
same and opposite contextual cues, respectively, selections of a nonarbitrary
comparison stimulus at either end of a specified physical dimension were
reinforced. Findings indicated a trend for improved performance with the
inclusion of selection-based feedback and the linked nonarbitrary–arbitrary
phase. There was a significant difference in yield between the RCP and MTS
conditions (84% vs. 56%, respectively). The implications of the findings for
contemporary research on derived relational responding are discussed.
