本文报道了三个实验，这些实验研究了在特定视觉空间工作记忆任务中表现的认知机制的本质，重点探索了中央执行参与的程度。实验1和2采用口头随机数字生成作为双任务范式下的执行任务。两个实验的结果都表明，涉及顺序处理信息的视觉空间任务比涉及同时处理的视觉空间任务对随机数字生成的干扰更大。第三个实验用口头随机数字生成替代不涉及序列顺序记忆的执行任务（警惕性任务改编自Vandierendonck， De voght, & Van der Goten, 1998b）。结果表明，警觉性任务与顺序视觉空间任务之间存在显著干扰，而与同步视觉空间任务之间无显著干扰。总的来说，这三个实验的结果被解释为表明连续连续的视觉空间任务比同时的视觉空间任务涉及执行资源的程度要大得多，这可能对试图利用这些任务来分离工作记忆中可分离的视觉和空间成分的研究有启示。
Three experiments are reported, which have investigated the nature of the cognitive mechanisms that underlie performance on specific visuo-spatial working memory tasks, with the emphasis on exploring the extent of central executive involvement. Experiments 1 and 2 employed oral random digit generation as an executive task within a dual-task paradigm. The results of both experiments indicated that visuo-spatial tasks that involve sequential processing of information show more interference with random digit generation than do visuo-spatial tasks that involve simultaneous processing. The third experiment substituted oral random digit generation for executive tasks that did not involve memory for serial order (vigilance tasks adapted from Vandierendonck, De Vooght, & Van der Goten, 1998b). The results indicated significant interference between the vigilance tasks and the sequential visuo-spatial task, but not with the simultaneous visuo-spatial task. Overall the results of the three experiments are interpreted as indicating that serial sequential visuo-spatial tasks involve executive resources to a significantly greater extent than do simultaneous visuo-spatial tasks, and that this can have implications for studies that attempt to make use of such tasks to fractionate separable visual and spatial components within working memory.
