This study examined the effectiveness of differential reinforcement of other behaviors technique to decrease the aggressive behaviors in intellectually weak students. The single-subject research method known as AB design was used and five intellectually weak male students that have been the most aggressive were selected as the subjects. The instruments used in this study included Durand’s Motivational Assessment Scale (1990), history questionnaire, questionnaire survey to evaluate the extension of treatment, interviews and behavioral observation. To implement the study, 9 cases of aggressive behavior in children that had the higher frequency were considered as the target behavior and then, using the behavior observation worksheet, the target behaviors were observed in four stages of B2, A2, B1, A1 and follow up and the results were recorded. To analyze the data, chi-square statistics, significance factor and the mean bisection method were used. Results showed that the differential reinforcement of other behaviors had a significant effect on aggression decrease in intellectually weak male boys and this effect was also stable over time and also had therapeutic effect in the natural environment and could also be generalized to the home environment. The results showed that the differential reinforcement of other behaviors can lead to aggression decrease in students.
