Abstract

Previous research on happiness as a conditioned emotional response in individuals with developmental disabilities is sparse. A better understanding of how stimuli come to elicit happiness is essential to improving quality of life. We attempted to establish object images as conditioned elicitors of smiling for three adults with developmental disabilities. Following identification of reliable elicitors of smiling, a forward-pairing discriminative conditioning procedure was used in which one image (CS+) was paired with an elicitor of smiling (US) while another image (CS-) was not. Repeated anticipatory smiling to the CS+ and not to the CS- was taken as evidence of respondent conditioning. Paired choice preference assessments using the CS+ and CS- images were conducted before and after the conditioning procedure, to evaluate the effects of training on preference for the CS+ image. Three sets of CS+ and CS- images were assessed, to demonstrate that preference changed only for the image set used in conditioning. This research will be extended by attempting to gradually replace the simple conditioned stimuli with compound stimulus situations more representative of natural situations.
