广泛的认知研究致力于视觉系统对不变统计信息的敏感性。例如，许多研究表明，当重复呈现视觉显示时，性能会提高。但是，是什么让人类将当前的视觉输入与先前的记忆联系起来呢？只有当整个输入的显示与先前的记忆匹配时，才能建立连接，还是检索依赖于输入和学习的显示之间的不完全匹配？使用视觉搜索任务，我们表明：（1）一旦学习了重复显示，即使传入的显示仅在3-4个位置与之匹配，受试者也可以检索它;（2）然而，在学习早期，重复一小部分显示不足以为重复的位置建立强大的记忆痕迹。我们认为，检索一个良好的视觉记忆可以进行，即使传入的显示部分匹配以前的记忆。
Extensive cognitive research has been devoted to the sensitivity of the visual system to invariant statistical information. For example, many studies have shown that performance improves when a visual display is presented repeatedly. But what allows humans to connect the current visual input to previous memory? Is the connection made only when the entire incoming display matches with a previous memory, or can retrieval rely on an incomplete match between the input and a learned display? Using a visual search task, we show that (1) once a repeated display is learned, subjects can retrieve it even when an incoming display only matches it in 3-4 locations; (2) however, early during learning, repetition of a small proportion of a display is not enough to establish a strong memory trace for the repeated locations. We suggest that the retrieval of a well-established visual memory can proceed even if an incoming display partly matches the previous memory.
