What is a false alarm?

Responding when a non-target letter appears — it reflects impulsivity or weak inhibition.

Is this a clinical ADHD test?

No. CPTs are used clinically, but this is a self-contained benchmark, not a diagnostic instrument.

Why hits minus false alarms?

It rewards both responding to targets and withholding on non-targets — the core of sustained attention.

このテストで測るもの

Concentration is a Continuous Performance Task: sustain attention over a stream of letters and respond only to the target 'X'. It measures sustained attention and response inhibition.

仕組み

Letters flash one at a time. Press the button only when you see 'X'. Pressing on any other letter is a false alarm. Your score is hits minus false alarms.

結果の計算方法

Your primary score is hits minus false alarms (higher is better), estimated against population norms.

精度と限界

Fatigue and attention affect results. This is a research-grounded task (Evidence B), not a clinical evaluation.
