Ten add twelve NeuroTracker sessions over four weeks to their training, tracking moving targets with their eyes on a 3D television, and ten do their usual training. In the 2020 paper the outcome is concentration, and the computer group's gain on the grid test is about double, 8.5 against 4.5, with little more than half an hour of actual task time across the whole month. In the 2021 paper the outcome is the score at 30 metres: up 32.9 points against up 19.7, with a significant difference between the groups. There are three caveats. The control group also improves a great deal, so the part attributable to the computer is about a dozen points; the control group does not spend equivalent time at a screen on a dummy task, so novelty and the attention received weigh alongside the exercise itself; and the paper on scores sits in a journal with questionable editorial standards. So the registry reports the result on scores but does not use it to decide the status, which remains not studied.claim:neurotracker-punteggio:revision:2026-09-11:2Fri, 11 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/mind/perceptual-cognitive-training-scoreclaim:neurotracker-punteggio:new_claim:2026-08-31:non_studiatoMon, 31 Aug 2026 08:00:00 GMT
