To determine the most effective language training activities for trainable mentally retarded (TMR) children, the variables of degree of previous language training, IQ, Peabody language treatment program versus Distar language treatment program, pretest versus posttest, and sex were examined with 122 TMR Ss (7 to 14 years old). Results of the…

To determine the effectiveness of the Peabody Language Development Kits over an extended period (2.5 years) with educable mentally retarded (EMR) children, daily oral language stimulation lessons using Levels One and Two of the kit were given to 27 classes for the EMR in schools with culturally disadvantaged populations.

During the 1973-74 school year, 230 trainable mentally retarded (TMR) children (ages 7 to 14 years) were exposed to one of two language training conditions: Distar or Peabody. A population of 116 continuees from the first year of the project and 114 new entries were assigned in as random a fashion as possible to either Distar or Peabody. Ss were…

Effects of the different components of the Distar language program were tested on 48 trainable mentally retarded (TMR) children. Three designs were used comparing IQ, sex, continuation status, selected standardized test results, and replicates. Results indicated that the degree of previous formal language training (continuation status) did not…
