Abstract：
Iconic memory and short-term memory are not only crucial for perception and cognition, but also of great importance to mental health. Here, we first showed that both types of memory could be improved by improving limiting processes in visual processing through perceptual learning. Normal adults were trained in a contrast detection task for ten days, with their higher-order aberrations (HOA) corrected in real-time. We found that the training improved not only their contrast sensitivity function (CSF), but also their iconic memory and baseline information maintenance for short-term memory, and the relationship between memory and CSF improvements could be well-predicted by an observer model. These results suggest that training the limiting component of a cognitive task with visual perceptual learning could improve visual cognition. They may also provide an empirical foundation for new therapies to treat people with poor sensory memory.
摘要：
标志性记忆和短期记忆不仅对感知和认知至关重要，而且对心理健康也很重要。这里,我们首先证明，这两种类型的记忆都可以通过感知学习改善视觉处理中的限制过程来改善。正常成年人接受了十天的对比检测任务训练，与他们的高阶像差(HOA)实时校正。我们发现训练不仅改善了他们的对比敏感度函数(CSF)，还有他们的标志性记忆和基线信息维护，用于短期记忆，记忆和CSF改善之间的关系可以通过观察者模型很好地预测。这些结果表明，通过视觉知觉学习训练认知任务的限制部分可以改善视觉认知。它们也可能为治疗感觉记忆力差的人的新疗法提供经验基础。
