چکیده

هدف: تخمین شناختی تلاش برای ارائه یک پاسخ معقول براساس اطلاعات در دسترس است. هدف از این مطالعه طراحی آزمون تخمین شناختی و بررسی روایی، پایایی و مقادیر هنجار آن است. روش: این مطالعه در 643 نفر از دانشجویان دانشگاه شهید بهشتی انجام شد. آزمون‌های تخمین شناختی طراحی شده در مطالعه حاضر، آزمون مرتب کردن کارت­‌های ویسکانسین، آزمون رنگ واژه استروپ و آزمون حافظه فعال چند محرک پیشین به عنوان آزمون­‌های کارکرد اجرایی همزمان برای ارزیابی مورد استفاده قرار گرفت. از آزمون همبستگی پیرسون برای بررسی روایی همزمان، آزمون تی برای مقایسه دو جنس، آزمون آلفای کرونباخ برای بررسی پایایی استفاده شد. نتایج: یافته­‌ها نشان داد تخمین در وجوه مختلف با یکدیگر همبستگی دارد. وجوه مختلف تخمین شناختی در دو جنس متفاوت است و همبستگی
معنی‌­داری بین نمره آزمون تخمین با متغیر­های آزمون ویسکانسین و آزمون چند محرک پیشین وجود دارد. همبستگی معنی­‌داری بین نمره تخمین و آزمون استروپ وجود نداشت. نتیجه‌گیری: آزمون طراحی شده آزمونی روا و پایا برای سنجش تخمین است. تخمین به عنوان سازه‌ای مستقل از وجوه اطلاعات با کارکردهای اجرایی همبسته است.

چکیده [English]

Aim: Cognitive estimation refers to an attempt to provide a relatively reasonable answers based on relevant knowledge. The purpose of this study was development of a cognitive estimation test and evaluation of its validity, reliability and normal value. Method: In this cross-sectional study, 634 students of Shahid Beheshti University were evaluated with cognitive estimation, Wisconsin card sorting, color-word stroop and N-back tests. Results: Findings show significant correltion between estimation accuracy in different modalities. Cognitive estimation accuracy was correlated with the measures of Wisconsin card sorting and N-back tests, but not Stroop test. Conclusion: Cognitive estimation test is a reliable and valid test. Cognitive estimation is an amodal construct and correlated with cognitive flexibility and working memory.
