The temporal oddball effect (Birngruber, Schröter, and Ulrich, in press; Pariyadath and Eagleman, 2007; Schindel, Rowlands, and Arnold, 2011) describes the finding that rare, deviant stimuli (oddballs) are temporally overestimated as compared to standards of equal physical duration. In a typical oddball paradigm, oddballs are presented at a random position within a stream of repeated standard stimuli. While the standards' duration is constant, oddball duration varies from trial to trial. After

In order to explain the oddball effect, it has been assumed that oddballs as compared to standards either attract more attention Open access under CC BY-NC-ND license. evoked PSEs smaller than the objective standard duration, no oddball effect was present in either block. Possible explanations for this result pattern will be discussed.
