认知负荷和控制性注意对工作记忆广度任务成绩的影响

THE EFFECTS OF COGNITIVE LOAD AND CONTROLLED-ATTENTION ON WORKING MEMORY SPAN TASKS

通过stroop干扰实验严格筛选被试,考察了控制性注意能力不同的被试在加工部分认知负荷不同的工作记忆广度任务中的成绩。结果表明:任务复杂性和加工速度对工作记忆广度任务成绩有重要影响,任务越复杂或加工速度越快,被试的工作记忆广度任务成绩越低;在复杂的和加工速度快的工作记忆广度任务中,控制性注意能力高的被试成绩要好于控制性注意能力低的被试,但在简单的和加工速度慢的任务中两者成绩没有显著差异。

In this article, we chose subjects strictly by experiment of stroop-interference and investigated the perfor- mance of high and low controlled-attention capacity subjects in working memory span tasks that cognitive loads of processing are different. The resuhs showed tasks complexity and processing speed have effects on performance of working memory span tasks, the more complex the task and faster the processing speed, the lower the performance. In more complex and faster tasks, the performance of high subjects were higher than the low, but these effects were not significant in more simple and slower tasks.
