People often want a quick check on whether their attention feels sharp after a notification-heavy day or poor sleep. A focus test that mixes odd-one-out puzzles with sustained-attention counting mirrors how researchers probe selective and sustained attention in lab settings, though our version is shortened for casual browsers. The habit section adds everyday context: phone checks during work, recovery time after interruptions, and whether interesting tasks pull you into hyperfocus.

Sample challenge: spotting that Triangle is the odd shape among Square, Pentagon, and Hexagon because it has three sides. Sample habit item: agreeing that you reach for your phone within minutes of starting focused work lowers your phone distraction domain score after reverse scoring. Neither item diagnoses anything; they only describe performance and self-report on this screener today.

Compare with sibling pages. The memory test scores recall drills that overlap when distraction breaks encoding. The IQ test covers broader reasoning puzzles. The cognitive test bundles working memory, math, pattern, verbal, and attention-switch warm-up items. The planned brain test will add processing-speed themes. For clinical inattention overlap, see the ADHD test on our mental health hub with its own limits.
