P300 correlates of inspection time

The P300 is an easily elicited psychophysiological phenomenon that may reflect phases of information processing inherent in many complex cognitive endeavors. In this study, cortical event-related potentials were collected from 49 subjects during an inspection time task. P300 amplitude at the temporal and occipital sites correlated with inspection time and with performance on Ravenʹs Standard Matrices. This study supports some of the previous work on P300 correlates and suggests that future integration of the IT and ERP paradigms will be fruitful.
