NEURAL CORRELATES OF SIGNAL DETECTION UNDER NON-AROUSAL AND AROUSAL CONDITIONS

Date Issued:

Summary:
A signal detection experiment tested the assumption that the results of Hillyard, Squires, Bauer and Lindsay (1971), who found a significant late positive component (LFC) of the averaged evoked potential only in the hit category, were due to the response set of their Ss and not to any unique associations of the LPC with the hit category as interpreted by them. Phase 1 of the present study was basically a replication of Hillyard's study. In Phase 2 incorrect responses were punished by an unpleasant feedback device designed to place more equal relevance on signal and non-signal trials. Significant LPCs appeared in both signal and non-signal brain waves under both phases indicating that the LPC is not contingent on any particular response category as Hillyard reported, but may instead reflect the relevance of the category to the experimental task as it is perceived by the S.
