摘　　要：设计了 2种不同的有意识的靶字母搜索实验 ,研究感觉记忆信息的受控加工 .实验 1根据感觉记忆和工作记忆的时间特征 ,将搜索作业严格限制在工作记忆中 .实验 2则未作这种限制 .结果显示 ,实验 1中靶字母搜索的正确率为 5 1.8% ,实验 2中靶字母搜索的正确率高达 78.2 % .2种搜索作业的成绩差异极为显著 .根据这一结果有理由认为 ,实验 2的搜索过程不是发生在工作记忆 ,而是它前级的感觉记忆 .也就是说 ,有意识的加工 ,可以在感觉记忆中进行 .In this paper, experiments of conscious target searching tasks were designed to validate Sensory Memory′s role in controlled information processing. In the experiments, there were two patterns of target searching task being designed.In pattern 1, the target searching was limited strictly in working memory according to the time character of sensory memory and working memory,while in pattern 2,there was no such limit. The results show, the correctness rate of target searching in the former was 51.8%, but the correctness rate in the latter was 78.2%, the difference of which was significant. It is reasonable to consider that target searching in pattern 2 didn′t take place in working memory,but in sensory memory.That is to say, controlled information processing can be carried out in sensory memory.
