چکیده

هدف پژوهش حاضر، بررسی اثر تمرین با خطای بینایی ابینگهاوسبر یادگیری مهارت هدف‌گیریدر افراد مستقل از زمینه و وابسته به زمینهبود.دراینراستا، آزمونگروهی تصاویر پنهانشده بین 300دانش‌آموز پسربا میانگین سنی 08/1 ± 86/13 سال توزیع شد. براساسنمره‌هایبهدستآمده از آزمون، 60نفر بهصورتتصادفی در چهار گروه 15نفری مستقل از زمینه با ادراک هدف بزرگ‌، وابسته به زمینه باادراک هدف کوچک‌، مستقل از زمینه با ادراک هدف کوچک‌ و وابسته به زمینه با ادراک هدف بزرگ‌، به‌صورت همگنتقسیم شدند. برای اطمینان از تفاوت‌نداشتن گروه­ها، پیش‌آزمون اجرا شد.شرکت­کنندگان تکلیف شوت تیلهرا بهمدت سه جلسه و هر جلسه، سهدسته کوشش پنجاه‌تایی را با خطای مربوطبه گروه خود تمرین کردند. با فاصلة 24 ساعت بی­تمرینی، آزمون یادداری و 72 ساعت بعد، آزمون انتقال (همانند یادداری یک دسته کوشش چهل‌تایی) اجرا شدند. برای تحلیل داده­ها از آزمون آنوای دوطرفه و برای بررسی اثر متقابل از آزمون تعقیبی توکی استفاده شد. مقایسة نتایج نشان دادکه اثر اصلی سبک ‌شناختی در یادداری و اثرهای اصلی (سبک شناختی و خطای بینایی) و همچنین، اثر متقابل (خطای بینایی × سبک شناختی) در انتقال معنادار بودند (P < 0.05). یافته­ها تفاوتیمعنادار بین گروه وابسته به زمینه با خطای بینایی ادراک بزرگ‌و سه گروه دیگر نشان داد.به‌‌طورکلی، این پژوهش نشان دادکه برای افراد وابسته به زمینه تمرین با هدف بزرگ‌ درک‌شده،تأثیر منفیدارد وتمرین با هدف کوچک‌ درک‌شده یک مزیت است.

چکیده [English]

The aim of present study Esfahan was to examine the effect of practice with Ebbinghaus' illusion on targeting skill performance in field dependence and field independence individuals. The Group Embedded Figure Test was distributed among 300 male students with the average age of 13.86±1.08. On the basis of the test results 60 people were divided into four groups (n=15) field independence on large target perception, field dependence on small target perception, field dependence on large target perception, field independence on small target perception groups. A pre-test was conducted to ensure that there were no differences between the groups at pre intervention time; the participants practiced marble shooting, (3×50 trials) in three sessions based on their groups. After 24 and 72 hours from the last practice session, retention and a transfer test was taken respectively. For analyzing data, two-way ANOVA and Tukey test were used. The results showed a significant difference between the main effect cognitive style on retention test and between the main effects cognitive style, visual error and the interaction effect (visual error×cognitive style) in the transfer test (P<0.05). Findings showed a significant difference between the field dependent group with the larger perceived target and the other groups (P<0.05). This study suggests that practicing with a larger perceived target for individuals who are field dependence, has a negative effect and, practicing with a smaller perceived target is an advantage for them.
