How to use

  1. 1.Start the fixed six-comparison route and inspect the asymmetric reference and candidate outlines.
  2. 2.Choose Same rotation when the object is only turned, or Mirrored when its handedness has been reflected; use buttons, S, or M.
  3. 3.Resume after leaving the tab and read the final accuracy and time only as details from this recreational route.

About Mental Rotation Test

Mental Rotation Test is a six-round shape comparison game made from original asymmetric polygons. Each round places a reference object beside a candidate object. The candidate is either the same object turned by a quarter, half, or three-quarter rotation, or a reflected version that has also been turned. Your task is simply to choose Same rotation or Mirrored. The page does not use a published psychometric card, clinical test sheet, population sample, percentile table, copyrighted stimulus set, or hidden scoring model. The points and shapes are Lizely fixtures created for this recreational route, so the final number describes only these six comparisons.

The activity is deliberately different from the existing Shape Rotation Match game. That game asks you to drag one object across a coordinate field and align its position and angle. This page never asks for translation or precise placement. It presents two static objects and asks about identity under rotation versus reflection. Every base polygon has an uneven outline with a notch or offset arm, because a symmetric object could look unchanged after a reflection and make the question ambiguous. The release tests independently check that no reflected base polygon is identical to any of its zero-, 90-, 180-, or 270-degree rotations.

Choose Start when you are ready. On each comparison, inspect the direction of the notches and long edges rather than only the overall tilt. Use the labelled buttons, press S for Same rotation, or press M for Mirrored. One visible comparison accepts one response. A held key, stale click, repeated event, response after completion, or input while the spreadsheet-style boss screen is open cannot score the next item. The route has three same-object answers and three mirrored answers in a disclosed fixed order. A fixed route makes browser acceptance reproducible, but repeated play also makes the shapes familiar, so it must not be treated as a fresh standardized measurement.

Timing is local and narrow. The browser records the visible interval between a comparison appearing and an accepted answer. If the tab becomes hidden, the active comparison pauses. Resume starts a fresh visible interval for that same item, so time spent on another tab, notification, call, or app is not shown as deliberate response time. This does not control hardware, screen size, browser scheduling, zoom, input method, interruptions, familiarity, visual accessibility settings, fatigue, or ordinary daily variation. The average is a convenient session detail, not laboratory timing.

After the sixth choice, the result panel shows correct answers, percentage, average visible response time, and points. Each correct answer is worth 100 points. There is no speed bonus, penalty band, age adjustment, benchmark, grade, cutoff, or interpretation of a positive or negative personal trait. The shared game shell can remember a best points value in this browser, but it does not create an account, upload answers, or publish a leaderboard. Restart returns to the same six original comparisons with an empty response history.

The interface uses inline SVG so the outlines remain crisp when zoomed. The shapes are accompanied by Reference and Candidate text, while the answers are named in full and available as native buttons. Meaning does not depend on colour. Touch, pointer, and keyboard players use the same state transition. Everything runs locally after the page loads; no image, camera input, microphone input, file, identity, or response history is sent to Lizely.

This is an entertainment exercise, not a clinical/IQ/cognitive assessment. It does not diagnose spatial ability, measure intelligence, or show whether your brain has improved. It has no professional, health, educational, employment, eligibility, screening, treatment, or placement meaning. If you need an evaluation or accessibility support, use an appropriate qualified service rather than a six-item browser game.

Methodology & sources

Six original trials use three asymmetric polygon fixtures. Each candidate is generated from a disclosed quarter-turn rotation with or without horizontal reflection, while a literal test oracle fixes the expected same/mirrored route and independently proves that no reflected base polygon equals any quarter-turn rotation. Each visible trial accepts one response token, hidden-tab timing pauses, and the completion panel reports only route accuracy, average visible response time, and 100 points per correct answer. No norm, copied assessment card, clinical cutoff, or external score table is used.

Frequently asked questions

Is this Mental Rotation Test a clinical or IQ assessment?
No. It uses six original product-authored SVG comparisons with no norm group, clinical protocol, percentile, cutoff, or intelligence interpretation.
How is this different from Shape Rotation Match?
Shape Rotation Match is a drag-and-align game. This page compares two static asymmetric objects and asks whether the candidate is rotated or mirrored.
Why does a comparison pause when I leave the tab?
The pause keeps background time out of the local visible-response average. Resume starts a fresh visible interval for the same item.
