Mental Lapses and Event-Related Potentials.

Abstract

Event-related potentials (ERPs) were recorded from 10 subjects as they performed an acoustic target detection task. Each subject's ERPs were sorted by performance level, on a trial-by-trial basis. A number of ERP measuring procedures then were compared in terms of their abilities to detect episodes of low behavioral performance. The ERP feature that proved most sensitive to fluctuations in performance was P3 (P300) amplitude. Weighted, time-averaged amplitude measures outperformed peak amplitude measures by a substantial margin. The results are discussed as they bear on using ERPs to detect lapses of equipment operator performance. Keywords: Performance assessment, Event-related potentials, Evoked potentials, Psychophysiology. (sdw)
