What Is a Focus Test?
A focus test measures your ability to sustain attention and selectively respond to relevant stimuli while ignoring distractions. This type of assessment is based on principles used in clinical attention testing, adapted into an accessible online format.
Sustained attention — the ability to maintain focus over time — is one of the core components of executive function. It plays a critical role in work productivity, learning, driving, and virtually every area of daily life that requires concentration.
How This Test Measures Focus
During the 30-second test, yellow targets appear at random positions. Your job is to click them quickly and accurately. Red distractor targets also appear — clicking these penalizes your score. This combination measures both sustained attention (clicking targets consistently) and selective attention (avoiding distractors).
Your final score reflects accuracy, speed, and consistency. A high streak indicates strong sustained focus, while a high hit rate with few wrong clicks indicates good selective attention.
