A few dots will flash pink β remember them. All dots then move randomly. When they stop, click the dots you were tracking.
Multi-object tracking (MOT) is a foundational paradigm in vision science, developed by researchers Zenon Pylyshyn and Ron Storm in the late 1980s to study how many independent moving items your visual attention can track simultaneously without confusing them for the distractor dots around them. Most untrained people can reliably track 3-4 targets at once; the number drops sharply beyond that as targets start swapping identities in your attention without you noticing.
This exact divided-attention skill is core to fast-paced team sports like soccer and basketball, where players must track multiple teammates and opponents simultaneously while moving themselves, and it's also used in vision-science research on air traffic control and video-game esports performance. This free multi-target tracking test gives you an instant score showing your maximum tracking capacity.
Competitive gamers in fast-paced shooters and real-time strategy games often reference multi-object tracking capacity as one of several perceptual skills that separates elite players from casual ones - being able to keep tabs on multiple enemies, teammates, or units on screen without losing track of any single one is directly analogous to this lab-standard cognitive test.
Don't try to look directly at every target - keep your gaze centered and use peripheral awareness for the outer dots.
Panicking when targets get close together makes tracking worse - a relaxed, wide focus works better than intense staring.
Team sports that require tracking multiple players show measurable transfer to this exact multi-object tracking skill.
Sports psychologists assessing team-sport athletes, esports players benchmarking their attentional capacity, air traffic controller trainees, and vision-science researchers all use variations of this multi-object tracking paradigm to measure divided visual attention.
This test is based on the Multiple Object Tracking (MOT) paradigm, first formally developed by vision scientists Zenon Pylyshyn and Ron Storm in a widely cited 1988 study, which found that most people can accurately track roughly four moving objects simultaneously among visually identical distractors, a number that has proven remarkably consistent across decades of follow-up research using many different display setups and object types. Successfully tracking multiple independently moving targets requires dividing your visual attention across several locations at once, rather than sequentially glancing between them, since the objects move continuously and unpredictably.
MOT tasks like this one are widely used in sports science research specifically because they correlate meaningfully with performance in team sports involving fast-changing spatial awareness, such as basketball, hockey, and rugby, where a player must simultaneously track teammates, opponents, and the ball or puck without fixating on any single one of them for long.
The consistent "roughly four objects" tracking limit found across MOT research is generally explained by a theory of attention allocation in which each tracked object consumes a share of a limited, shared attentional resource - once that resource is divided among too many targets, the tracking signal for each individual object becomes too weak and noisy to reliably follow, causing tracking to fail, usually all at once rather than gradually. Some studies on elite athletes in fast-paced sports have found modestly higher tracking capacities than the general population average, suggesting this capacity, while largely stable, may be partially trainable through extensive sport-specific practice.
Smooth Pursuit Tracking and Target Interception both test single-object tracking and timing rather than divided attention across multiple objects, making them useful comparison points for isolating exactly which part of your dynamic vision is strongest.
Research consistently finds a hard capacity limit around 4 items for most people - this isn't a flaw in your attention, it's a well-documented property of the human visual system.
Several studies have found modest improvements in multi-object tracking capacity after sustained action video game practice, though results vary by individual.
Yes, completely free with instant scoring and a global percentile comparison, no signup required.
Multiple object tracking is the ability to visually follow several moving targets simultaneously among similar-looking distractors, a well-studied paradigm in attention research.
Most people can accurately track around 3-4 moving objects simultaneously before accuracy drops off sharply, a limit widely replicated in cognitive science research.
Air traffic controllers, athletes in team sports, and competitive gamers all rely heavily on multi-object tracking ability in real-world performance.
Yes, several studies show sports and video game players who track fast-moving objects regularly perform better on MOT tasks than non-players.
