Background and Aim: Speech is the essential need of the social life. To acquire that, children highly rely on the normal senses and speech full environment. The normal auditory senseis the most important need. Early amplification intervention in children with hearing difficulties is advised. Cochlear implant technology provides an effective help for hearing-impaired children in recent decades. With regards to new and limited implantation services in Iran, the effects of operation age on speech and language of implanted children was not studied yet. The purpose of this study was to compare articulation errors in cochlear implanted children with different operation age.
Materials and methods: In this cross-sectional study, ten cochlear implanted children before three and eleven after four years old were evaluated. The participants were without any anatomical, visual, and intelligence abnormality and 2.5-3 years was passed from their operation. Then, by using Picture Pho-netic Test (PPT), the articulation errors of individuals were extracted and for more evaluation of the er-rors and complete of PPT, we, also used their excited connected speech by presenting pictures. By application of t-test and using SPSS software, the data was analyzed.
Results: Data analysis indicated that, there was meaningful significant difference between substitute errors and whole errors in two gropes but there was not meaningful significant difference between de-stroyed errors in two gropes.
Conclusion: The children who undergoing operation after 4 years old had severed articulation disorder than other grope. These issues indicated that the earlier operation of children will lead to improve the speech skills and reduced the articulation errors.

Background and Aim: Reading is one of the human's communicative skills. Phonological awareness and rapid automatized naming are parts of the person's linguistic knowledge. Research in different languages and communities suggest that there is a relation between phonological awareness, rapid automatized naming and reading. To survey these relations in Persian language is the aim of this study.

Methods: In this study 130 male students from the first grade were selected at random. They were normal in IQ, visual and hearing status. Language development was also normal in these children. This study was a cross-sectional one. Pearson correlation coefficient and linear regression test were used to analyze data.

Results: The relation between phonological awareness and automatized rapid naming was significant (p<0.0001). Pearson correlation coefficient between phonological awareness and reading was direct (0.86). Pearson correlation coefficient between rapid automatized naming and reading was indirect that equals -0.87. In investigating the relation of two variables simultaneously with reading we concluded that the relation between phonological awareness, rapid automatized naming and reading is statistically significant (p<0.0001).

Conclusion: The results of this research revealed that in Persian language like other languages there is a relation between phonological awareness, rapid automatized naming, and reading. Reading skills of children could be improved with this exercises.
