We investigated the relationship between, and functional significance of, P 300, novelty P 3, and the pupil dilation response ( PDR ). Subjects categorized stimuli including (a) words of a frequent category, (b) words of an infrequent category (14%), and (c) pictures of the frequent category (“novels”; 14%). The P 300 and novelty P 3 were uncorrelated with the PDR and differed in their response to experimental manipulation. Therefore, although the three physiological responses often co‐occur, they appear to each manifest a distinct function: The PDR may be more closely linked to aspects of behavioral responding than the event‐related potentials. Within participants, P 300 and PDR latencies accounted for unique portions of the reaction time variance, and amplitudes of all three responses were larger for stimuli recalled on a subsequent test, compared to not recalled. We discuss the possibility that all three responses reflect norepinephric input from the locus coeruleus.
