A Laboratory for the Experimental Analysis of Developmentally Retarded Children

Abstract

University of IV~hingron Laboratory methods for the study of learning, conditioning, perception, and motivation in children have recently been adapted from techniques developed for infra-human Ss by Skinner and by Harlow. Appropriately modified, the free-operant situation and the Wisconsin General Test Apparatus have been put to use in the study of human behavior (e.g., Bijou, 1957; Lindsley, 1956; Zearnan, House, & Orlando, 1958). Little experimental rigor and control has been lost in the process of adjusting the techniques for human -Ss. It has now become possible to study human behavior without sacrificing the precision and objectivity which characterizes most animal research. The purpose of this paper is to describe a laboratory which incorporates these methods for research with developmentally retarded children3 and some of the modifications that have been made in tailoring them for this group. The plan of the presentation is to discuss in turn the physical layout, features of each experimental situation, and control and recording operations. In addition, some of the special considerations of laboratory research in an institutional setting are presented, primarily with respect to operational routines and unique characteristics of the Ss.
