Early Post-Stimulus Activity Negatively Predicts P300 Amplitude: A Single-Trial Analysis of the Auditory Oddball Task

2026-01-27

Abstract excerpt

<title>Abstract</title> <p>The P300 event-related potential is a core index of attention and context updating, yet the trial-by-trial factors that modulate its amplitude remain incompletely characterized. This study tested whether early post-stimulus signal magnitude (0–150 ms) predicts subsequent P300 amplitude (300–600 ms) at the single-trial level. Using data from the ERP CORE auditory oddball dataset (N = 40...
