Five preschool children at risk for mental retardation were taught to choose an odd stimulus which varied in one important dimension (e.g., form, color, or size) from other stimuli in a set. Oddity responding was shown to transfer across stimulus types, and learning was maintained for a minimum of six weeks. (Author/JW)

A study of the acquisition of mands (requests) and tacts (labels) relating to food and eating utensils in three individuals with severe mental retardation revealed that responses acquired as tacts did not readily occur as mands, but spontaneous manding was developed through a stimulus control transfer procedure.

The response satiation model of instrumental performance was used in two experiments to establish contingencies which reduced the self-injurious behavior of two adults with profound mental retardation and multiple handicaps. Transfer and generalization of training effects were also observed. (Author/DB)
