摘要：The present study attempted to produce generalized breakequivalence responding with 5 adult subjects. A Generalized BreakEquivalence Pattern (GBEP) involved responding in accordance withsymmetry and transitivity but not with equivalence in new situations.That is, having been trained in two conditional discriminations, A 1-B1/A2-B2 and B1-C1IB2-C2, subjects should produce the followingderived relations; B1-A1 , B2-A2, C1-B1, C2-B2, A1-C1 , A2-C2, C1-A2, C2-A 1. To achieve this goal, in Phase 1 subjects were exposedto explicit training in broken symmetry (A 1-B1 , A2-B2, B1-A2, B2-A 1)with 3 different stimulus sets (4 stimuli per set). They were thentrained in symmetry (A1-B1 , A2-B2, B1-A1 , B2-A2) with 3 new sets(4 stimuli per set). In Phase 2, subjects were exposed to TrainStandard Equivalence (i.e., training in the conditional discriminationsA1-B1 , A2-B2, B1-C1 , B2-C2). Then they received Train BreakEquivalence (i.e., training in the conditional discriminations B1-A1 ,B2-A2, C1-B1 , C2-B2 [symmetry]; A 1-C1, A2-C2 [transitivity], C1-A2,C2-A 1 [break equivalence]) and were finally exposed to a nofeedbackcondition with the relations trained during the Train BreakEquivalence. This sequence was repeated with three differentstimulus sets (6 stimuli per set). Finally, in Phase 3 subjects weretested for the generalization of the BEP with a new stimulus set (6stimuli per set). In this phase subjects were exposed to TrainStandard Equivalence and immediately after to a Generalization Test(GT). Three subjects showed a clear GBEp, 1 subject produced avery close result to the GBEP with errors on the transitive relation,and 1 subject failed to show the predicted pattern. These dataprovide some support for the suggestion that derived relationalresponding is an overarching or generalized operant class.
