图像记忆是一种前范畴的、高容量的、快速衰减的可见记忆，这种观点最近受到了攻击。Colheart，1980）。人们已经区分了可见的持久性，或一个熄灭的刺激的现象性痕迹，和信息持久性，关于刺激的视觉特性的知识。在3个实验中，对13名大学生和本文作者的两种不同的信息持久性概念进行了测试。一种概念是，视觉信息持续存在于视觉记忆中，该记忆从刺激偏移开始并持续150-300毫秒，与暴露时间无关。第二个概念是，信息持久性来自于非视觉记忆，它包含了展示物品的空间坐标沿着以及这些物品的身份代码。在实验中，3× 3字母阵列呈现的持续时间从50到500毫秒不等。在阵列偏移提示报告整个阵列行之后，以不同间隔显示的单个字符掩码。线索行的掩蔽和未掩蔽的字母的比较显示，空间特定的视觉（即，掩蔽）信息持续刺激偏移后，无论曝光时间。这一结果有利于信息持久性的视觉概念。也有支持，但是，非视觉概念：准确性增加，项目入侵错误减少刺激持续时间的增加。信息持久性和跨扫视整合模型的影响进行了讨论，在阅读。(47参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
The view of iconic memory as a precategorical, high-capacity, quickly decaying visible memory has recently come under attack (eg, M. Coltheart, 1980). Distinctions have been drawn between visible persistence, or the phenomenal trace of an extinguished stimulus, and informational persistence, knowledge about the visual properties of the stimulus. Two alternative conceptions of informational persistence were tested in 3 experiments with 13 university students and the present authors. One conception is that visual information persists in a visual memory that begins at stimulus offset and lasts for 150–300 msec, independently of exposure duration. The 2nd conception is that informational persistence arises from a nonvisual memory that contains spatial coordinates for displayed items along with identity codes for those items. In the experiments, 3× 3 letter arrays were presented for durations ranging from 50 to 500 msec. A single character mask presented at varying intervals after array offset cued report of an entire row of the array. Comparison of the cued row's masked and unmasked letters revealed that spatially specific visual (ie, maskable) information persisted after stimulus offset, regardless of exposure duration. This result favors the visual conception of informational persistence. There was also support, however, for the nonvisual conception: Accuracy increased and item intrusion errors decreased as stimulus duration increased. Implications for models of informational persistence and for transsaccadic integration during reading are discussed.(47 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
