چکیده
هدف پژوهش حاضر بررسی مولفه دیداری- فضایی حافظه فعال و حافظه کوتاه مدت در دانش آموزان با اختلالاتیادگیری و مقایسه آن ها با دانش آموزان عادی است.30 دانش آموز با اختلالات یادگیری (از هر یک از گروه های اختلالات خواندن، ریاضیات و املا 10 دانش آموز) و 10 دانش آموز عادی پایه سوم دبستان های شهر اصفهان به روش نمونه گیری تصادفیخوشه ای چند مرحله ای انتخاب شدند. ابزار های مورد استفاده، آزمون ایرانی کی مت، مقیاس شناسایی دانش آموزان با ناتوانییادگیری در املا، آزمون تشخیص سطح خواندن، مقیاس هوش کودکان وکسلر، مصاحبه بالینی و تکلیف بلوک های کرسی برای ارزیابی مولفه دیداری- فضایی حافظه فعال و کوتاه مدت بود. داده ها با روش تحلیل واریانس مورد تجزیه و تحلیل قرار گرفت. نتایج پژوهش نشان داد که در دو مولفه دیداری- فضایی حافظه فعال و حافظه کوتاه مدت در بین دانش آموزان با اختلالات یادگیری ریاضی، خواندن، املا و دانش آموزان عادی تفاوت معناداری وجود دارد.بدین صوت که دانش آموزان با اختلالیادگیری ریاضی در این مولفه ها از سه گروه دیگر عملکرد پایین تری دارند.دانش آموزان با اختلالات یادگیری به ویژه اختلال ریاضیدر مولفه دیداری- فضایی حافظه فعال و کوتاه مدت دارای نارسایی هستند.این مشکل باید در این

دانش آموزان تشخیص داده شده و هدف مداخله قرار گیرد.

چکیده English

The aim of this research was to investigate visual-spatial component of working memory and short-term memory in students with learning disorders and comparison with normal students.

30 3rd grade elementary students with learning disorders and 10 3rd grade elementary normal students were selected through multistage random cluster sampling. The instruments were Scale for Identifying Students with Spelling Learning Disability, Keymath Test, Reading Level Diagnostic Test, Wechsler Intelligence Scale for Children (WISC), Clinical Interview and Corsi Blocks Task for assessing visual-spatial component of working memory and short-term memory. Data were analyzed by ANOVA. The results showed that there is a significant difference between students with reading, mathematics and spelling learning disorders and normal students in visual-spatial component of working memory and short-term memory. Students with mathematics disorder had lower performance in these components. Students with learning disorders particularlymathematics disorder had deficits in visual-spatial component of working memory and short-term memory. This problem should be assessed in order to plan appropriate interventions.
