In contrast to our rich sensory experience with complex scenes in everyday life, the capacity of visual working memory is thought to be quite limited. Here our memory has been examined for the details of naturalistic scenes as a function of display duration, emotional valence of the scene, and delay before test. Individual differences in working memory and long-term memory for pictorial scenes were examined in experiment 1. The accumulation of memory for emotional scenes and the retention of these details in long-term memory were investigated in experiment 2. Although there were large individual differences in performance, memory for scene details generally exceeded the traditional working memory limit within a few seconds. Information about positive scenes was learned most quickly, while negative scenes showed the worst memory for details. The overall pattern of results was consistent with the idea that both short-term and long-term representations are mixed together in a medium-term 'online' memory for scenes.
与我们在日常生活中对复杂场景丰富的感官体验形成对比的是,视觉工作记忆的容量被认为相当有限。在此,我们针对自然主义场景的细节进行了记忆研究,该研究考察了显示时长、场景的情感效价以及测试前的延迟等因素。实验1中研究了个体在对图片场景的工作记忆和长期记忆方面的差异。实验2中探究了对情感场景的记忆积累以及这些细节在长期记忆中的保留情况。尽管在表现上存在很大的个体差异,但对场景细节的记忆通常在几秒钟内就超过了传统的工作记忆极限。关于积极场景的信息学得最快,而消极场景的细节记忆最差。结果的总体模式与以下观点一致,即在中期的场景“在线”记忆中,短期和长期表征混合在一起。
