Pre-experimental Stimuli Functions in Equivalence Class Formation

Abstract Can pre-experimental conditional relations that elicit emotional responses, such as jealousy, affect the formation of equivalence classes? Would there be differences between men and women? To address these questions, 19 participants of both sexes were exposed to training and testing of the formation of four equivalence classes, one consisting of the boyfriend’s/girlfriend’s name, an unknown woman’s/man’s name, and two unfamiliar figures. After the tests, the Romantic Jealousy Scale was applied. Participants classified as having a higher degree of jealousy did not form equivalence classes regardless of whether they were men or women. It is suggested that pre-experimental relations with affective functions interfere in the formation of equivalence classes in which the boyfriend’s/girlfriend’s name should be related to the unknown woman’s/man’s name.
