    Objectives: Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) is a useful tool for the quantitative evaluation of auditory behaviors in different situations. The present study aimed to develop the Persian version of IT-MAIS. Methods: There was 4 main steps in the translation and validation of the scale, as follows: forward translation, synthesis, backward translation, and expert committee discussion. Then, the final Persian version of the scale was analyzed in terms of reliability and validity. The scale was studied on the parents of 17 hearing impaired and 17 normal hearing children. Results: There was a significant difference in the mean score of scale between hearing impaired and normal hearing children (P≤0.001). The internal consistency of the items was satisfactory. The Cronbach’s alpha for the overall score was 0.93. Discussion: This study suggested that IT-MAIS-F can be a reliable and valid tool for the evaluation of the auditory function of children. However, the sample size of the study was small. Thus, studies with larger sample sizes are recommended. In addition, test-retest reliability of the scale was not studied.

    Effects of congenital hearing loss and cochlear implantation on audiovisual speech perception in infants and children
    (IOS Press, 2010) Bergeson, Tonya R.; Houston, Derek M.; Miyamoto, Richard T.; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Purpose Cochlear implantation has recently become available as an intervention strategy for young children with profound hearing impairment. In fact, infants as young as 6 months are now receiving cochlear implants (CIs), and even younger infants are being fitted with hearing aids (HAs). Because early audiovisual experience may be important for normal development of speech perception, it is important to investigate the effects of a period of auditory deprivation and amplification type on multimodal perceptual processes of infants and children. The purpose of this study was to investigate audiovisual perception skills in normal-hearing (NH) infants and children and deaf infants and children with CIs and HAs of similar chronological ages. Methods We used an Intermodal Preferential Looking Paradigm to present the same woman’s face articulating two words (“judge” and “back”) in temporal synchrony on two sides of a TV monitor, along with an auditory presentation of one of the words. Results The results showed that NH infants and children spontaneously matched auditory and visual information in spoken words; deaf infants and children with HAs did not integrate the audiovisual information; and deaf infants and children with CIs initially did not initially integrate the audiovisual information but gradually matched the auditory and visual information in spoken words. Conclusions These results suggest that a period of auditory deprivation affects multimodal perceptual processes that may begin to develop normally after several months of auditory experience.
