在一系列同质标准中出现的罕见刺激（古怪的刺激）的持续时间往往被高估。这种时间古怪效应（OE）被归因于知觉过程。OE通常通过比较判断任务进行评估。然而，有人认为，这项任务容易产生决策偏差。目前的实验采用比较和平等判断，因为有人认为平等判断不太容易受到这种偏见的影响。实验1a和1b采用视觉刺激，实验2采用听觉刺激。研究结果没有提供强有力的证据表明决策偏差会影响OE。此外，计算模型清楚地表明，平等判断并不特别适合于区分感知效应和决策效应。综上所述，目前结果的模式与OE的感知起源最一致。
The duration of rare stimuli (oddballs) presented within a stream of homogenous standards tends to be overestimated. This temporal oddball effect (OE) has been attributed to perceptual processes. The OE is usually assessed with a comparative judgment task. It has been argued, however, that this task is prone to decision biases. The present experiments employed comparative and equality judgments, since it has been suggested that equality judgments are less vulnerable to such biases. Experiments 1a and 1b used visual stimuli, and Experiment 2 auditory stimuli. The results provide no strong evidence for decision biases influencing the OE. In addition, computational modeling clearly suggests that the equality judgment is not particularly suited to distinguish between perceptual and decisional effects. Taken together, the pattern of the present results is most consistent with a perceptual origin of the OE.
