Background and Objective: Mentally retarded children delayed in global that affects motor, cognitive, communication, speech and language development. Poor organization in mental lexicon and reduction in vocabulary are the obvious consequences of mental retardation. The main objective of this study was to evaluate perception and expression of nouns, and test-retest reliability of two picture-pointing and picture-naming tests, in Farsi-speaking in educable mentally retarded children in Hamadan city.
Materials and Methods: It was a descriptive-analytic and cross-sectional study. 40 mentally retarded children (18 females, 22 males) were selected from exceptional children’s school of Hamadan. Two picture-pointing and picture-naming tests were used in this study. For the sake of test-retest reliability, 10 evaluated two times with one day time interval.
Results: There was a significant positive correlation between mean scores of perception and expression (P=0.001, r=0.662). Mean scores of girls and boys was not statistically different. Findings about test-retest reliability show that, these two tests have optimal reliability.
Conclusions: Descriptive statistics of the mentally retarded children can be part of normative data alongside other findings of other cities of Iran. In addition, confirmation of reliability shows part of the efficiency of these two tests in research and clinical settings.
