Originally developed in 1978 by Vandenberg and Kuse [5] based on the research by Shepard and Metzler (1971), [1] a Mental Rotation Test (MRT) consists of a participant comparing two 3D objects (or letters), often rotated in some axis, and states if they are the same image or if they are mirror images (enantiomorphs).

Mental rotation task. Cube assemblages based on test drawings used by Shepard and Metzler. Two-dimensional figures similar to those used in work by Shepard and Cooper. Inspired by a dream of three-dimensional objects rotating in space, Shepard began in 1968 to design experiments [3] to measure mental rotation. (Mental rotation involves ...
The types of rotation tests used by Shepard and Metzler One theory of the mind that was examined in these experiments was the "brain as serial computer" philosophical metaphor of the 1970s. Psychologist Zenon Pylyshyn theorized that the human mind processes mental images by decomposing them into an underlying mathematical proposition.
The Mental Rotations Test is a test of spatial ability by Steven G. Vandenberg and Allan R. Kuse, first published in 1978. It has been used in hundreds of studies since then. [1] [2] A meta-analysis of studies using this test showed that men performed better than women with no changes seen by birth cohort. [3]
The test takes about 10 minutes to complete and is scored out of 30 points, with 30 being a perfect score. It’s composed of sections that look at several components of cognitive function ...
Example of mental rotation task stimuli. Shepard and Metzler (1971) presented a pair of three-dimensional shapes that were identical or mirror-image versions of one another. RT to determine whether they were identical or not was a linear function of the angular difference between their orientation, whether in the picture plane or in depth.

In 1971, Roger Shepard and Jacqueline Metzler tested Pylyshyn's particular hypothesis that all symbols are understood by the mind in virtue of their fundamental mathematical descriptions. [9] Shepard and Metzler's experiment consisted of showing a group of subjects a 2-D line drawing of a 3-D object, and then that same object at some rotation.
