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.
