Description
Lutz, Park, Rast, Baldwin, Larson, and Clayson track brain signals of performance monitoring trial by trial in twenty twenty-six. People adjust their behaviour after errors and hard trials. Brain potentials linked to monitoring may drive those adjustments. Past work averaged signals per person, which can hide trial level links.
They analysed a flanker task in two hundred ninety-one healthy adults. Several brain potentials were measured on each trial. Models predicted response time and accuracy on the current trial from prior and current signals. Those signals added unique predictive value beyond task conditions alone. Within person swings in the signals tracked dynamic shifts in cognitive control. The authors argue variability is a functional signature, not noise.
