With an average of (100.86) degrees, and a standard deviation of (5,628) degrees on the Stanford-Binet scale, the fifth picture, using the one-group design. Saafan, and Doaa Khattab), the linguistic scale for pre-school children (Arabization / Ahmed Abu Haseba), and the training program based on the strategies of applied behavior analysis (prepared / researcher). The results showed that there were statistically significant differences at the level (0.01) between the The averages of the scores of the experimental group in the pre and post measurements of expressive language in favor of the post-measurement, and there were no statistically significant differences between the averages of the scores of the experimental group (from linguistically retarded children) in the post and follow-up measurements of expressive language, after the completion of the application and during the follow-up period.
