Multiple Drawing Functions in Equivalence Classes

Abstract

Using nonsense syllables to form two 3-member stimulus equivalence classes (A1-B1-C1, A2-B2-C2), this study examines the effects of training drawing functions at two stimuli within Class 1 (B1 & C1). Within Experiment 1, participants were instructed to draw a ‘stickman’ and a ‘stickwoman’ at B1 and C1 respectively. Subsequent tests for function transfer revealed various novel drawings that often included a combination of the originally trained drawings at A1. Experiment 2 modified the training by showing drawings of the figure of a ‘stickman’ and ‘stickwoman’ that were required at B1 and C1; results were similar to those seen in Experiments 1. Experiment 3 simplified the drawing function to the left-hand arc of a circle and the right-hand arc of a circle. The majority of participants responded at A1 by drawing various combinations of the behaviours trained at B1 and C1. Results are discussed in the context of the emergence of novel behaviour.
