SELECTIVE TRACKING

Maintain discrete attention on multiple moving targets.

Cognitive psychologist Zenon Pylyshyn proposed in 1988 that the attention system maintains discrete, individuated pointers on selected objects — he called them FINSTs, Fingers of INSTantiation. The research that followed established a hard architectural limit: humans can track approximately four independent moving objects simultaneously.

This limit is robust across cultures, ages, and stimulus types. It is not a skill threshold — it is a capacity constraint built into the dorsal frontoparietal network. Corbetta and Shulman's landmark 2002 paper mapped the neural circuitry: the intraparietal sulcus and frontal eye fields coordinate to maintain attentional grip on moving targets.

Motion Bind is built around this ceiling. The early levels are below it. The later levels breach it. The game does not ask you to exceed the limit — it asks you to perform near it. Where your performance degrades is data.

Your SELECTIVE TRACKING is unmeasured.
