Is this a measure of intelligence?

No. Reaction time is a speed benchmark. It correlates with some cognitive constructs but is not an IQ test.

Why are my phone and desktop results different?

Touch and display input pipelines add different amounts of latency. We store device and input class so norms stay fair.

What counts as a false start?

Responding before the green signal appears. False starts are flagged and don't count toward your median.

反応時間

How fast do you respond to a visual signal?

~2 min

測定値は端末・入力方法・画面のリフレッシュレート・OS・環境に依存します。実験室レベルの精度ではありません。

このテストで測るもの

Reaction Time measures the time between a visual signal appearing and your response. It is a direct benchmark of your sensorimotor speed, not a psychological trait.

仕組み

Wait for the panel to turn green, then respond as quickly as you can. You get 3 practice trials and 15 scored trials with randomized foreperiods to prevent anticipation.

結果の計算方法

Your result is the median of 15 valid trials in milliseconds. Faster is better. False starts and tab-blur events are flagged and excluded from the median. Device and input latency affect results, so phone and desktop are not directly comparable.

精度と限界

Hardware latency, monitor refresh rate and browser backgrounding can all shift results. This is a utility benchmark (Evidence C), not a clinical measure.

Reaction Time and Cognitive Performance

Reaction time — the milliseconds between a stimulus and your response — is one of the oldest and most reliable measures of cognitive processing speed. Over a century of research has linked it to intelligence, aging, sleep, and even longevity.
