Two adults with severe mental retardation were assessed for correct pointing responses to line drawings of required eating utensils. Following tact intervention, mands for two of three utensils emerged. Results suggest transfer from tact variables to the conditioned establishing operation may be facilitated by cultivating a minimal mand…

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.

Studies assessing treatments for severe behavior problems of developmentally delayed persons were reviewed. Procedures used in the 382 studies, published from 1967-1987, were analyzed in terms of problem behaviors, side effects, and treatment methods. Also examined were number of studies reported yearly, maintenance and generalization of effects,…

This study examined the matching and sequencing of quantities, numerals, and arbitrary forms by two individuals with mental retardation. Results showed that sequence training did not readily lead to new matching performances, unlike prior research with college students. Instead, training in matching to sample yielded emergent sequence production…

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)
