Habituation of the orienting response elicited by novel events is a crucial mechanism underpinning selective attention. The purpose of the current study was to investigate if the habituation rate is increased given that the deviating events occur in a predictable pattern. A cross-modal oddball task in which the participants categorized visual targets across 6 blocks of trials was used. Each visual target was preceded by a sound. In most trials, the sound was a standard sound, on rare trials, however, the visual target was preceded by a deviant sound. In on condition, the deviants were presented every 10th trial, and in another condition, the deviants occurred in a pseudo randomized order. Habituation was observed in both conditions, but there was no difference regarding habituation rate. The results indicate that habituation rate does not depend on the temporal regularity of the surprising events, which could be used to facilitate their prediction.
