为了阐明视觉长期记忆（VLTM）和在线视觉处理之间的关系，我们研究了VLTM是否以及如何不自觉地影响一个一次变化检测任务的性能，使用由六个无意义的几何对象组成的图像。在研究阶段，参与者观察变化前（实验1），变化后（实验2），或前后变化（实验3）出现在随后的变化检测阶段的图像。在变化检测阶段，一个对象总是在变化前和变化后的图像之间发生变化，并且参与者报告哪个对象发生了变化。结果表明，VLTM的变化前的图像增强了变化检测的性能，而变化后的图像的准确性下降。之前暴露于变更前和变更后图像不会影响性能。这些结果表明，变化前的信息在变化检测中起着重要的作用，VLTM中与当前任务相关的信息并不总是对性能有积极的影响。(C)2014爱思唯尔公司All rights reserved.
To clarify the relationship between visual long-term memory (VLTM) and online visual processing, we investigated whether and how VLTM involuntarily affects the performance of a one-shot change detection task using images consisting of six meaningless geometric objects. In the study phase, participants observed pre-change (Experiment 1), post-change (Experiment 2), or both pre- and post-change (Experiment 3) images appearing in the subsequent change detection phase. In the change detection phase, one object always changed between pre- and post-change images and participants reported which object was changed. Results showed that VLTM of pre-change images enhanced the performance of change detection, while that of post-change images decreased accuracy. Prior exposure to both pre- and post-change images did not influence performance. These results indicate that pre-change information plays an important role in change detection, and that information in VLTM related to the current task does not always have a positive effect on performance.
