A previous study by Roche and Barnes (1997) examined the transformation of conditioned sexual arousal in accordance with arbitrary relations. The current research replicated and extended that study by attempting to bring the derived transformation effect under contextual control. In Experiment 1, the functions of hand waving and clapping were first established for two nonsense syllables (called 81 and 82, respectively). Subjects were then exposed to relational pretraining, similar to that employed by Steele and Hayes (1991) Opposite/B1-C2; Opposite/B2-C1. During a testing phase, the stimulus functions established for B1 emerged for C1 in the presence of Same (Le., the subjects waved) but those established for B2 emerged for C1 in the presence of Opposite (Le., the subjects clapped). Similarly, the functions of B2 emerged for C2 in the presence of Same (Le., the subjects clapped), but those established for 81 emerged for C2 in the presence of Opposite (i.e., the subjects waved). Experiment 2 established similar results using respondent eliciting functions in the place of hand clapping and waving.The analysis of derived relational responding is both interesting and important because it has opened up new vistas of research into human language and complex behavior. Most research on derived relational responding has focused on the familiar stimulus equivalence effect.
