The rapid detection of changes in sensory information is an essential process for survival. Individualhumans are thought to have their own intrinsic preattentive responsiveness to sensory changes. Herewe sought to determine the relationship between auditory change-related responses and personal-ity traits, using event-related potentials. A change-related response peaking at approximately 120 ms(Change-N1) was elicited by an abrupt decrease in sound pressure (10 dB) from the baseline (60 dB) ofa continuous sound. Sixty-three healthy volunteers (14 females and 49 males) were recruited and wereassessed by the Temperament and Character Inventory (TCI) for personality traits. We investigated therelationship between Change-N1 values (amplitude and latency) and each TCI dimension. The Change-N1 amplitude was positively correlated with harm avoidance scores and negatively correlated with theself-directedness scores, but not with other TCI dimensions. Since these two TCI dimensions are associ-ated with anxiety disorders and depression, it is possible that the change-related response is affected bypersonality traits, particularly anxiety- or depression-related traits.
