title: N1-P2 correlates of reaction time at the single-trial level.
abstract: Using a template-matching pattern recognition technique evaluated in an earlier paper, the amplitude and latency of the N1-P2 wave of the vertex visual evoked potential was established on each trial of a reaction time task. This single-trial physiological information correlated meaningfully with trial-by-trial changes in performance, providing further indication of the validity and practicability of a single-trial approach to the analysis of human EP data.
