WM3 is a computer program that is used to test the 2D mental rotation (Mental rotation task).
In a 2D mental rotation test, the subject is asked to compare two or more 2D objects (or images) and state if they are the same image or if they are mirror images or if they are completely different images. Commonly, the test will have pairs of images each rotated a specific amount of degrees (e.g. 20°, 75°, 140° or 180°). Some pairs will be the same image rotated, some will be different, and some will be mirrored.
Within this program, you can choose from four basic types of experiment (test). With these experiments we examine how quickly and accurately a person differs same (rotated) from different (mirror or completely different) images.
The images (stimuli) are created using a mathematical algorithm so that it is quite difficult to verbalize ("nonverbal" stimuli).
You can change a number of settings of the test, which affects the degree of difficulty of the test: a form of stimulus, stimulus presentation time, the length of the delay, the number of correct responses, test duration, the degree of similarity of target and non-target stimuli, the appearance of the screen during the experiment..
WM3 is Freeware software and is designed primarily for scientific and research purposes.
