Posttests revealed the emergence of symmetry relations in the form of oral naming skills by both children. (Contains 2 figures.)

Sensitivity to reinforcement contingencies was examined in six individuals with mental retardation using a concurrent operants procedure in the context of a computer game. Results included individual differences in sensitivity and differential sensitivity to rate and magnitude variation. Results suggest that comprehensive assessments of potential…

Areas of controversy covered center around the nature of the disorder, the effects of drugs, and methodological problems. Alternative approaches offered focus on evaluation and remedial techniques. (DLS)

This study, an approach to controlling "acting-out" behaviors of handicapped children in elementary schools, describes the use of a home-based dependent group contingency to eliminate the destructive behavior (fire-setting, vandalizing property) of a mildly retarded eight-year-old boy. (Author/PN)
