چکیده: (7375 مشاهده)
هدف از پژوهش حاضر تعیین تاثیر انجام همزمان تکالیف شناختی که دو مولفه حلقه واج شناختی و لوح دیداری-فضایی حافظه کاری را فعال می کنند بر الگوی راه رفتن افراد سالمند بود. بدین منظور، 12 سالمند سالم با دامنه سنی 65-70 سال به صورت در دسترس از سراهای محله شهر تهران انتخاب شدند و تکلیف راه رفتن را به صورت توازن متقابل در سه شرایط آزمایشی مجرد، همزمان با تکلیف دیداری–فضایی و همزمان با تکلیف واج شناختی اجرا کردند. در حین آزمون، کوشش های راه رفتن توسط دستگاه تجزیه و تحلیل حرکت ثبت و داده های مرتبط با الگوی راه رفتن با استفاده از آزمون تحلیل واریانس با اندازه های تکراری تحلیل شد. نتایج نشان داد که بین سه شرایط آزمایشی در زمان گام، آهنگ گام برداری، تغییرپذیری دامنه شتاب و عرض گام تفاوت معناداری وجود دارد (0.05p< ) و فعال شدن لوح دیداری-فضایی در مقایسه با حلقه واج شناختی تداخل بیشتری در راه رفتن ایجاد می کند. بنابراین به نظر می رسد لوح دیداری-فضایی حافظه کاری در طرح ریزی و اجرای تکلیف راه رفتن نقش داشته باشد.
