Ten author-contributed papers present information on stimulus control research and developmental disabilities. Articles address such isues as the role of naming, development of stimulus classes, control by exclusion, and comparison of trial-and-error and graduated stimulus change procedures. (CL)

The nature of stimulus and response generalization is discussed, and a number of tasks related to generalization that are commonly taught in early childhood programs are identified. Research evidence concerning generalization is reported, as are recommendations for enhancing generalization. (Author/LB)
