摘要/Abstract

摘要： 检验工作记忆广度机制的四个模型：资源共享模型、任务转换假说、干扰说和时间资源共享模型。以60名大学本科生为被试,完成工作记忆广度任务和转换任务。结果表明：加工时间和加工项目数不是影响工作记忆广度的主要因素;工作记忆广度受到加工速度的影响;工作记忆广度和线索-任务转换代价呈显著的负相关关系。结果支持时间资源共享模型,工作记忆广度取决于注意在加工和存储之间快速、灵活的转换。

关键词: 加工时间, 加工速度, 加工项目数, 转换代价

Abstract: This article tested four models according to working memory span: resource-sharing model, task-switching model, interference account and the time-based resource-sharing model. We manipulated processing time, processing amount and processing rate of the processing component. 60 undergraduates were assigned to complete one type of working memory span task and a switching efficiency task. The results showed that:(1)Processing time and processing amount did not affect working memory span;(2)Working memory span was affected mainly by processing rate;(3)There was a significantly negative correlation relationship between working memory span and cue-task switching cost. The results supported the time-based resource-sharing model and working memory span depended a rapid and flexible switching of attention from processing to maintenance.

Key words: processing time, processing rate, processing amount, switching cost
