The role of contextual factors on duration estimates was investigated, employing 6 time intervals ranging from 15 to 35 sec (demarcated by the onset and termination of a display panel of lights). When compared with earlier research, the results suggest that duration estimates are affected by the context of the stimulus intervals with regard to other stimuli in the series. Specifically, those stimuli that were overestimated when they were the shortest members of the series were underestimated when they were the longest intervals of the stimulus series. In addition, a lengthening effect was observed: duration estimates increased over blocks of trials for all stimulus intervals.
研究了情境因素对时长估计的作用，采用了6个时长从15秒到35秒不等的时间间隔（由一组灯光显示面板的亮起和熄灭来界定）。与早期研究相比，结果表明，时长估计会受到刺激间隔情境的影响，这种影响与系列中的其他刺激有关。具体而言，那些在作为系列中最短刺激时被高估的刺激，在作为刺激系列中最长间隔时则被低估。此外，还观察到一种延长效应：在所有刺激间隔的试验组中，时长估计都有所增加。
