A visuospatial task in which participants judge whether two rotated shapes are the same or mirror-image different.
Configure parameters and run an interactive preview exactly as participants will experience it. No data is recorded.
Adjust parameters below, then start the preview on the right.

Task parameters
6 base shapes rendered on a 4×4 grid with random rotations. Half same, half different per sequence.
This is a researcher preview. No participant data is recorded.
Simulated participant view
A visuospatial task in which participants judge whether two rotated shapes are the same or mirror-image different.
No data is recorded
Two shapes rendered on 4×4 grids are shown side by side. The participant taps Same or Different as quickly as possible.
Useful in studies targeting visuospatial ability, sex differences in cognition, athletic performance, or engineering aptitude where spatial processing is relevant.
Not well-suited to populations with strong visual field impairments or when study design requires classical Shepard-Metzler 3-D stimuli.
Enable practice with feedback to ensure participants understand that same-shape pairs may look different because they are rotated, not mirrored. Keep sessions to 20 trials or fewer for EMA use.
Mental rotation performance is stable across brief administrations. Both accuracy and reaction time are informative — fast but inaccurate responses suggest impulsive guessing.
