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.

이 테스트가 측정하는 것

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.

작동 방식

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.

결과 계산 방법

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

정확도와 한계

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