Titration of Limited Hold to Comparison in Conditional Discrimination Training and Stimulus Equivalence Testing
Psychological Record Volume 62, Number 2, ISSN 0033-2933
Reaction time (RT), thought to be important for acquiring a full understanding of the establishment of equivalence classes, has been reported in a number of studies within the area of stimulus equivalence research. In this study, we trained 3 classes of potentially 3 members, with arbitrary stimuli in a one-to-many training structure in 5 adult participants, using a touch screen and software-based recordings. After training the conditional relations, a limited hold (LH) was calculated for each of the 5 participants based on actual RT. Training with a titrating LH in 100-ms steps was conducted until all the participants responded within 1.2 s. Finally, programmed consequences were thinned before testing. We arranged an LH of 2.5 s during the testing for emergent relations. 1 of the 5 participants was found to demonstrate stimulus equivalence. The pattern of increasing RT from baseline trials to symmetry and equivalence test trials was not found. (Contains 2 tables and 9 figures.)
