Task parameters
Practice uses a smaller grid (18 items). Main data: hits, omissions, false taps, and completion time.
This is a researcher preview. No participant data is recorded.
Simulated participant view
A visual scanning task where participants tap designated targets among distractors.
No data is recorded
A grid of symbols, letters, or icons with touch selection of targets.
Useful for selective attention and concentration studies, including lower-frequency executive screening.
Less suitable when visual acuity, motor precision, or very small screens are major concerns.
Use alternate forms and ensure touch targets are large and well spaced.
A stronger visual-attention task than odd-one-out, but also slightly heavier in motor and visual demands.
