Test your dynamic visual attention and spatial working memory. Track the highlighted target dots as they mix among identical distractors, and identify them once movement stops.

How This Test Works
1
What It Measures
Measures sustained visual attention, dynamic spatial indexing, and active visual working memory capacity. It evaluates your brain's ability to lock onto multiple target paths simultaneously while ignoring identical decoy objects.
2
How Scoring Works
Your score is the number of target dots correctly identified across 5 rounds. We track your choices, speed multiplier, and strikes (max 3 failures) to calculate a percentile rank compared to our normative attention database.
What Affects Your Results
Mental fatigue, screen size (larger viewports push targets into the periphery), display refresh rates (smoother movement prevents tracking loss), and current stress levels impact performance.

What is a Multiple Object Tracking Test?
A Multiple Object Tracking (MOT) test is a standard cognitive assessment used in neuropsychology to study visual attention limits. In an MOT task, a set of identical circles moves randomly across a screen. At the start, a subset of these circles is highlighted as "targets." They then return to their original appearance and begin moving. Your goal is to track these targets and click them once the motion ceases.
Unlike static focus games, MOT requires active, continuous spatial processing. It forces your brain to distribute its attentional resources across multiple coordinate vectors simultaneously, highlighting the limits of visual working memory capacity.
How Many Moving Objects Can You Track?
In cognitive science, the baseline human limit is typically described as 3 to 4 objects. However, this capacity varies significantly based on individual training, age, and neurological traits. Action gamers, professional athletes, and aviation pilots routinely demonstrate the ability to track 5 or more targets simultaneously under high-velocity conditions.

How to Improve Multiple Object Tracking Capacity
Attentional tracking is a highly plastic neural resource. You can train your brain to expand its tracking limits using these strategies:
Practice Peripheral Expansion: Instead of focusing your gaze directly on a single dot, try to soft-focus on the center of the canvas. This relies on your peripheral vision to capture motion vectors.
Sustained Attention drills: Consistently playing MOT games for 10-15 minutes a day builds attentional stamina and trims target indexing latencies.
Optimize Refresh Rate: High-refresh rate displays (e.g. 144Hz+) render object movement more fluidly, preventing the "jumpy" motion that causes tracking loss on lower 60Hz displays.

A Multiple Object Tracking (MOT) test measures your ability to visually track a subset of moving items (targets) among identical moving distractors. It is a standard experimental paradigm used in cognitive psychology to assess dynamic visual attention, working memory, and tracking capacity.
How many moving objects can a human track at once?
Research shows the typical human limit is tracking 3 to 4 objects simultaneously. Elite athletes, action video game players, and military pilots can often track 5 or more objects under demanding conditions.
Can you train your multiple object tracking capacity?
Yes. Studies demonstrate that systematic training on MOT tasks can expand your tracking capacity, improve peripheral target detection, and enhance sustained attention span over time.
How does display size affect object tracking performance?
Larger displays spread objects over a wider field of view, forcing reliance on peripheral vision. This increases tracking difficulty compared to small displays where objects are concentrated in the central foveal view.
Is this object tracking test a medical diagnostic tool?
No. This test is designed purely for cognitive self-tracking, performance benchmarking, and educational training. It does not diagnose clinical attention deficit disorders (ADHD) or visual impairments.
Why do action video games improve tracking ability?
Fast-paced action and tactical video games require players to monitor multiple threats, allies, and parameters simultaneously, which naturally trains and expands visual-spatial attention resources.
Does age affect visual tracking performance?
Yes. Multiple object tracking performance generally peaks in early adulthood (ages 18-25) and shows a gradual decline with age due to decreases in visual working memory capacity and processing speeds.
How do distractors impact object tracking capacity?
decoy distractors increase cognitive load by competing for attentional indexing. When distractors move faster or pass closer to target objects, the probability of attentional tracking errors increases.
