What does the mental rotation test measure?

Vandenberg and Kuse’s [1] Mental Rotation Test (MRT) is one of the most commonly used measures of spatial abil- ity. Performance variability on this test is frequently substan- tial, even in groups of high-ability subjects such as university students.

In a mental rotation test, the participant compares 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).

One may also ask, what were the dependent variables in the mental rotation task you performed? The dependent variable was performance (rotation rate and accuracy) on the Mental Rotation test.

Subsequently, one may also ask, why did Shepard & Metzler 1971 findings suggest that mental images were similar to real images?

Shepard and Metzler’s findings suggest that mental images were similar to real images because when subjects were presented with two similar but rotated images it took longer for the subjects to determine of the images were the same due to the increasing difference of the angle.

What is mental scanning?

A mental scanning task is an experimental technique that has been used to support the depictive theory of imagery proposed by Kosslyn (Kosslyn, 1980, 1994; Kosslyn, Thompson & Ganis, 2006). In a mental scanning task, subjects are asked to scan across a mental image and the latency of the scan is measured.

What is mental imagery in psychology?

Mental imagery can be defined as pictures in the mind or a visual representation in the absence of environmental input. For most of us, mental imagery during states of wakefulness is faint or difficult to manipulate. The best way to make imagery more vivid is to imitate the conditions of sleep.
