The Mental Rotation Test reports accuracy and visible-tab response time as two independent details from a six-comparison browser game, not as a combined score, an ability ranking, or a percentile against any norm. The page fixes six original asymmetric SVG pairs in a disclosed order, asks one Same rotation or Mirrored decision per pair, and ends with a result panel that lists correct answers, a percentage, an average visible response time, and points. There is no speed bonus, penalty band, age adjustment, benchmark, grade, cutoff, or interpretation of a positive or negative personal trait. Because the two numbers are reported separately, a reader can compare them within the route without confusing fast clicks for skill or treating slower correct answers as a deficit. Understanding what each number does and does not cover is the first step to reading the panel honestly.
What the route measures and what it deliberately skips
The route is six original asymmetric polygon comparisons. 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. Three of the six fixed comparisons are Same rotation answers and three are Mirrored answers, in a disclosed order that makes browser acceptance reproducible.
The points and shapes are Lizely fixtures created for this recreational route, so the final number describes only these six comparisons. The page does not use a published psychometric card, clinical test sheet, population sample, percentile table, copyrighted stimulus set, or hidden scoring model. There is no speed bonus and no penalty band, which means a slow correct answer is worth the same 100 points as a fast correct answer, and a fast wrong answer still scores zero.
That separation is the practical answer to anyone asking about mental rotation accuracy vs speed in this specific game: the two outcomes travel on parallel tracks and never combine into a single number. A reader can use each one as a route detail without it being read back as a personal trait, a benchmark, or a clinical cutoff.
How to read accuracy and average response time side by side
The result panel shows four values: correct answers, a percentage, an average visible response time, and total points. The percentage is the same information as correct answers, just scaled out of six. The average response time is the mean of the visible intervals the browser recorded for the six accepted responses. If a tab became hidden during a comparison, that active comparison paused and the resume started a fresh visible interval for the same item, so time spent on another tab, notification, call, or app is not counted as deliberate response time.
| Aspect | Accuracy (correct out of 6) | Average visible response time |
|---|---|---|
| What it covers | Six fixed Lizely-fixture comparisons in a disclosed order | The visible interval per comparison that produced an accepted answer |
| What it excludes | Repeated play, familiarity, hardware, browser scheduling, accessibility settings | Time spent on another tab, paused sessions, fatigue, interruptions, ordinary daily variation |
| How it is reported | A single integer count and a single percentage | A single seconds value averaged across the six accepted responses |
| How it interacts with points | Each correct answer contributes exactly 100 points; wrong answers contribute zero | Time has no effect on points; there is no speed bonus or penalty band |
| What it is not | A percentile, a benchmark, a clinical cutoff, or an age-adjusted grade | Laboratory timing, hardware-adjusted timing, or an ability score |
Because both columns are reported as plain numbers without statistical framing, the comparison stays descriptive. A reader who wants to interpret a faster average against a higher accuracy can do so within the route, but the panel itself never says that one caused the other. The same separation is used in other fixed browser cognitive games, including the Digit Symbol Accuracy vs Speed report, where accuracy and timing travel on separate tracks for the same reason.
How to play the six-comparison route
The route is short and visible. Each comparison appears with a Reference object on one side and a Candidate object on the other, and exactly one response can be recorded per comparison.
- Open the Mental Rotation Test and choose Start to begin the fixed six-comparison route.
- Inspect the Reference outline and the Candidate outline, paying attention to the direction of notches, the long edges, and any offset arms rather than the overall tilt.
- If the Candidate is the same object only turned, choose Same rotation. If the Candidate's handedness has been reflected, choose Mirrored. Use the labelled buttons, the S key, or the M key.
- Continue through all six fixed comparisons. Each visible comparison accepts one response; held keys, stale clicks, repeated events, responses after completion, or input while the boss screen is open cannot score the next item.
- After the sixth accepted choice, read the result panel. It shows correct answers, a percentage, an average visible response time, and total points. There is no leaderboard, account, or upload; the panel only describes these six comparisons.
Restart returns to the same six original comparisons with an empty response history, so the second run starts from zero rather than carrying points or timing across sessions.
Same rotation vs Mirrored: what the choice actually asks
Each comparison asks one question: has the Candidate been only turned, or has it also been reflected? A quarter-turn, half-turn, or three-quarter-turn rotation keeps the object's handedness intact, so the direction of any notch and the relative orientation of any offset arm stay on the same side after rotation. A reflection reverses handedness, so the notch swings to the opposite side and the offset arm flips across an axis.
| Signal on the outline | Same rotation | Mirrored |
|---|---|---|
| Notch position after the turn | Stays on the same side relative to the long edge | Moves to the opposite side relative to the long edge |
| Offset arm orientation | Keeps its chirality when the object is turned | Flips chirality because of the reflection step |
| Overall tilt | May look like the reference is leaning, but the local details match | Can have any rotation angle; the local details are what give it away |
| Why asymmetric base polygons are used | A symmetric object could look unchanged after reflection and make the question ambiguous | Same reason; reflection is only visible when the base has an uneven outline |
Because every base polygon has an uneven outline with a notch or offset arm, the question is always answerable from local detail rather than from overall shape. The release tests independently check that no reflected base polygon is identical to any of its zero-, 90-, 180-, or 270-degree rotations, which keeps the Same/Mirrored split unambiguous for every comparison in the route.
Why the timer pauses when you leave the tab
Timing in this route 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; the timer does not silently accumulate background time. When you return, Resume starts a fresh visible interval for the same item. The pause is there to keep phone notifications, browser tab switches, calls, or quick app checks from showing up in the local visible-response average.
This does not control hardware, screen size, browser scheduling, zoom level, input method, interruptions, familiarity, visual accessibility settings, fatigue, or ordinary daily variation. The average is a convenient session detail, not laboratory timing, and the same is true of the percentage: it describes the six Lizely-fixture comparisons in this run, nothing else.
Limits of these two numbers and what this game is not
The accuracy percentage and the average visible response time are the only quantitative outputs the route produces, and they only describe the six original comparisons in the run that produced them. The page does not diagnose spatial ability, measure intelligence, or show whether a brain has improved, and it has no professional, health, educational, employment, eligibility, screening, treatment, or placement meaning.
Repeated play makes the fixed route familiar, which is why a second or third run cannot be treated as a fresh standardized measurement. Restart shows the same six original comparisons, so any score change between runs is a familiarity effect on a known route rather than a fresh measurement on new material. The shared game shell can remember a best points value in the local browser, but it does not create an account, upload answers, or publish a leaderboard. Everything runs locally after the page loads, so no image, camera input, microphone input, file, identity, or response history is sent to Lizely.
If a reader needs an evaluation, a screening, or accessibility support, the appropriate qualified service is the right route, not a six-item browser game. Used as a recreational route, the Mental Rotation Test's accuracy and visible-tab response time stay what they were on the result panel: two independent route details from a fixed set of original asymmetric comparisons.
