Abstract

Abstract: This study explores how trial‐to‐trial latency variability contributes to the developmental trends observed in ERN amplitude found in the incorrect trials of a performance monitoring task, the visual flanker task. An Adaptive Woody filter was used to measure and correct for the trial‐to‐trial latency variability of the ERN in 240 participants aged 7–25 years. Using three measures of latency variability, the degree of trial‐to‐trial latency variability was shown to decrease as the age of the participants increased from 7 to 25 years. The success of the Adaptive Woody filter technique to remove the trial‐to‐trial latency variability was demonstrated in a straightforward manner by the significant changes in the measures of fit and intraindividual variability obtained before and after applying the filter. After the latency variability effects were removed and adjusted averaged ERPs were obtained, a more subtle but significant nonlinear developmental trend was still found in the amplitude of the ERN component. Abstract : This article demonstrates the importance of considering latency variability when analyzing and interpreting ERP research, especially when the study includes children. The Adaptive Woody Filter was used to measure and correct for trial‐to‐trial variability. After latency variability effects were removed, a nonlinear developmental trend in participants aged 7 to 25 years was found in the peak‐to‐peak amplitude of the ERN ERP component elicited in a speeded visual flanker task.
