چکیده

مقدمه و اهداف
کم­شنوایی مرتبط با کاهش فعالیت­های شناختی است. استفاده از وسایل کمک ­شنیداری تاثیر مشکلات شنوایی بر مشکلات شناختی را کم می­کند. هدف مطالعه حاضر بررسی اثربخشی پروتز کاشت حلزون و سمعک روی توانایی حافظه فعال واج‌شناختی بود.
مواد و روش­ ها
تحقیق حاضر یک مطالعه مقطعی است و دارای حجم نمونه 63 کودک فارسی‌زبان در پایه اول دبستان (21 کودک کاشت حلزون، 21 کودک کاربر سمعک و 21 کودک شنوای طبیعی) بود. ابزار سنجش آزمون تکرار ناکلمه سیاحی و همکاران و خرده­آزمون‌های فراخنای اعداد در ترتیب مستقیم و معکوس نسخه 4 وکسلر بود.
یافته­ ها
یافته­ها نشان داد میانگین نمرات حافظه فعال واج‌شناختی در کودکان شنوای طبیعی در مقایسه با کودکان کم‌شنوای دارای کاشت حلزون و کاربر سمعک به ‌طور معناداری بالاتر بود (01/0P<)، اما تفاوت معناداری در میانگین نمرات حافظه فعال واج‌شناختی بین کودکان کم‌شنوای دارای کاشت حلزون و کاربر سمعک دیده نشد (05/0P>).
نتیجه­ گیری
بین کودکان آسیب شنوایی و شنوای طبیعی در حافظه فعال واج‌شناختی تفاوت دیده شد. این نشان‌دهنده نقش شنوایی در رشد حافظه فعال واج‌شناختی است؛ بنابراین به نظر می­رسد که در مطالعه حاضر نوع استفاده از وسایل کمک­شنیداری پروتز کاشت حلزون و سمعک تاثیری بر مهارت حافظه فعال نداشته است.

چکیده [English]

Background and Aim: Hearing loss is associated with poor cognitive performance. Using hearing aids reduces the impact of hearing loss on cognitive problems. The aim of the present study was to evaluate the effectiveness of cochlear implant and hearing aid on the children's phonological working memory ability.
Materials and Methods: In the current cross- sectional study, 63 Persian-speaking primary grade students (21 cochlear implant, 21 hearing aids, and 21 children with normal hearing) participated. The assessment tools used were Nonword repetition task of Sayyahi and forward and backward auditory digit spans from the Persian version of WISC-IV.
Results: The results showed that the means of scores for children with normal hearing in phonological working memory were significantly greater than those of children with severe-to-profound hearing loss with cochlear implants and hearing aids user (P<0/01). Mean scores of different skills in phonological working memory were not significantly different between the two groups of cochlear implant and hearing aid children (P>0/05).
Conclusion: According to the results, a significant difference exists between children with hearing impairment and normal hearing children in phonological working memory. This represents the role hearing sense plays in the development of phonological working memory. So, it seems that in the present study, the type and use of hearing aids) hearing aids and cochlear implant (had no effect on working memory skills.
