The present study examined how the perception of time is affected by the presence of a visual stimulus during the reproduction phase of an online time reproduction task. Participants were instructed to reproduce the durations of speed-altered speech snippets with either a picture or a blank screen presented during the reproduction phase. Results showed that fast speeches were reproduced as longer than slow ones, while the reproduced durations of short speeches were closer to the actual durations than were the long speeches. In addition, longer reproduced durations were observed in trials with a picture than in trials with a blank screen. These results provide clear evidence that postencoding information can influence the reproduction of previously encoded temporal intervals and are discussed in the context of attention allocation and its possible influence on an internal clock mechanism. Also, the study provides evidence that online testing is reliable for assessing biases in time perception, at least with time reproduction tasks.
本研究考察了在在线时间复制任务的复制阶段存在视觉刺激时，时间感知是如何受到影响的。参与者被指示使用在复制阶段呈现的图片或空白屏幕来复制语速改变的语音片段的时长。结果表明，快速语音被复制为比慢速语音更长的时长，而短语音的复制时长更接近实际时长，而长语音则不然。此外，在有图片的试验中观察到的复制时长比在有空白屏幕的试验中更长。这些结果清楚地表明，编码后信息可以影响先前编码的时间间隔的复制，并且在注意力分配及其对内部时钟机制的可能影响的背景下进行了讨论。此外，该研究还提供了证据表明，在线测试对于评估时间感知偏差是可靠的，至少对于时间复制任务是如此。
