Our ability to identify an object is often impaired by the presence of preceding and/or succeeding task-irrelevant items. Understanding this temporal interference is critical for any theoretical account of interference across time and for minimizing its detrimental effects. Therefore, we used the same sequences of 3 orientation items, orientation estimation task, and computational models, to examine temporal interference over both short (<150 ms; visual masking) and long (175-475 ms; temporal crowding) intervals. We further examined how inter-item similarity modifies these different instances of temporal interference. Qualitatively different results emerged for interference of different scales. Interference over long intervals mainly degraded the precision of the target encoding while interference over short intervals mainly affected the signal-to-noise ratio. Although both interference instances modulated substitution errors (reporting a wrong item) and were alleviated with dissimilar items, their characteristics were markedly disparate. These findings suggest that different mechanisms mediate temporal interference of different scales.
我们识别物体的能力常常会受到之前和/或之后与任务无关的项目的影响而受损。理解这种时间干扰对于任何关于跨时间干扰的理论解释以及将其有害影响降至最低都至关重要。因此，我们使用了相同的由3个方向项目组成的序列、方向估计任务和计算模型，来研究在短（<150毫秒；视觉掩蔽）和长（175 - 475毫秒；时间拥挤）间隔内的时间干扰。我们进一步研究了项目间相似度如何改变这些不同的时间干扰情况。不同尺度的干扰出现了定性不同的结果。长时间间隔的干扰主要降低了目标编码的精度，而短时间间隔的干扰主要影响信噪比。尽管这两种干扰情况都调节了替代错误（报告错误项目），并且随着项目不同而减轻，但它们的特征明显不同。这些发现表明，不同的机制介导了不同尺度的时间干扰。
