Abstract
One important aspect of Visuospatial Reasoning is the ability to rotate an object mentally. Presently, one of the most popular and widely used test of Mental Rotation is the Redrawn version of Vandenberg & Kuse Mental Rotation test (VMRT) However, this test has often been criticised to be more difficult because of its complicated scoring system. Present study compared this standard test of mental rotation ability with a newly constructed test with less number of items and less complicated scoring system. We collected data from 147 adolescent school students (Mean age=13.10 years; SD=1.84) by administering both the tests consecutively. Findings showed that VMRT has very high difficulty index as compared to the newly constructed test. The latter also proved to be a more reliable and valid measure of mental rotation ability as compared to VMRT. Discussion focused on the relative advantage of the newly constructed test for assessing mental rotation ability.
Highlights
One important aspect of Visuospatial Reasoning is the ability to rotate an object mentally
Prior studies on measuring Mental Rotation ability The first experiments performed by Shepherd & Metzler (1971) to measure mental rotation ability were based on the belief that individuals are often able to recognize rotated three-dimensional objects irrespective of the orientation
Objective of the study The objective of the present study is to examine whether the new test with a different scoring system is a better measure of mental rotation ability than the existing standard test
Summary
One important aspect of Visuospatial Reasoning is the ability to rotate an object mentally. Construction of Test Measuring Mental Rotation Ability of Adolescent High School Students The difficulty level of the item increases, not because the subject do not have the ability to mentally rotate the image, but because of greater taxation of working memory space.
