Most adults reliably track three moving objects.
The Criterion goes to five.
A short multiple-object tracking exercise, built for curiosity rather than measurement. It produces no score and proves nothing about you. What it does is let you feel the kind of attentional load the GFM battery measures properly.
Keep your eyes on the targets.
A set of dots will flash orange. Those are your targets. Everything then moves together and the targets become indistinguishable. When motion stops, select the ones you tracked.
Five rounds, about two minutes. The objects never speed up. What changes is how many you hold, and how long you hold them. Requires a mouse or touch.
Round complete.
A demo, not an assessment. The GFM battery runs a controlled version of this task under conditions that make the result meaningful.
Motion is reduced on this device.
The Criterion relies on continuous movement, so it is not shown here. In the full battery, multiple-object tracking is one of six measured tasks, administered under controlled conditions.
What this measures
Sustained attention and dynamic visual tracking under load. The paradigm comes from Pylyshyn and Storm (1988), who found people can track up to five targets among ten identical moving objects. Most adults hold about four.
What this is not
Not a measurement. This version varies several things at once for engagement, which means nothing here isolates a single ability. The GFM battery holds those variables constant, adds working memory, inhibitory control, and reaction-time tasks, and reviews them alongside your longitudinal physiology.
