What Do Online Attention Tests Measure? Accuracy, Response Time, and Limits
Understand the difference between a game score and a validated assessment, with a worked example of HypeVoro’s scoring and practical guidance for comparing results.
Online tasks can record correct answers, errors, and response times. Those numbers are not automatically a validated measure of attention. HypeVoro reports gameplay only and cannot diagnose ADHD or any other condition.
Revision note: Updated explanations, game-scoring details, and research links; removed unsupported or mismatched references. Corrected the game description for the maths-question format and linked the Focus Index methodology.
A measured response is not the same as a validated assessment
A browser can record a tap and measure elapsed time, but interpretation is a separate step. HypeVoro tells you what happened while you played its 30-second maths challenge. It has no clinical validation or population norms.
HypeVoro counts a tile attempt when you select one of the numbered buttons. Correct answers divided by all accepted tile attempts gives accuracy. Twelve correct answers plus three wrong tiles means 12 ÷ 15 = 80%.
Notification clicks are recorded separately. Your total mistakes combine wrong tiles and opened distractions, while your best streak is the longest sequence of correct answers without either kind of mistake. A later mistake does not erase an earlier best streak.
The exact HypeVoro score formula
Game score = round((60 × accuracy + 40 × resistance) × participation). Accuracy and resistance are fractions between zero and one. Resistance is resolved notifications dismissed or allowed to expire divided by all resolved notifications. Unfinished cards are excluded.
Participation is correct answers divided by twelve, capped at one. For twelve correct answers, three wrong tiles, three resisted notifications and one opened notification, the result is (60 × 0.8 + 40 × 0.75) × 1 = 78. With no correct answers, the result is zero. Missing accuracy or resistance contributes zero to the formula.
Response time runs from a question appearing until the correct tile is tapped. It includes time spent on any wrong attempts for that question and excludes pauses. The result reports an average plus the fastest and slowest correct responses; milliseconds are not added to the game score.
Semmelmann and Weigelt compared laboratory and web versions of cognitive tasks and found timing differences between settings. This supports caution when comparing absolute response times across setups. Their experiment does not supply a correction factor for your phone. Read the online timing study.
What the four stage summaries can tell you
Each stage shows correct tiles, wrong tiles, opened distractions, accuracy, and average response time. A card is attributed to the stage where it appeared. Stages vary in length and difficulty, so a raw mistake count is not a fair standalone comparison.
If no correct answers were recorded, response time is unavailable rather than zero. If no tile attempts were recorded, accuracy is unavailable. This distinction matters: missing evidence is different from very fast or perfectly accurate play.
How to use the result
Try the practice and play the free focus game. On a replay, compare a concrete part of your performance rather than treating a playful tier as a statement about your life. Fresh quick-play sequences, device differences and familiarity can all change a run.
A useful result separates accuracy, timing and mistakes, explains its formula, and admits what it cannot infer. HypeVoro’s score is a game result, not a clinical assessment.
