Continuity of spatial location was recently shown to improve the ability to identify and recall a sequence of target digits presented in a mixture of confusable maskers [Best et al. (2008). Proc. Natl. Acad. Sci. U.S.A. 105, 13174-13178]. Three follow-up experiments were conducted to explore the basis of this improvement. The results suggest that the benefits of spatial continuity cannot be attributed to (a) the ability to plan where to direct attention in advance; (b) freedom from having to redirect attention across large distances; or (c) the challenge of filtering out signals that are confusable with the target.
最近研究表明,空间位置的连续性能够提高识别和回忆出现在易混淆掩蔽信号混合中的目标数字序列的能力[贝斯特等人(2008年)。《美国国家科学院院刊》105卷,第13174 - 13178页]。进行了三项后续实验以探究这种提高的基础。结果表明,空间连续性的益处不能归因于以下几点:(a)提前规划注意力指向位置的能力;(b)无需在大距离间重新引导注意力;或(c)过滤掉与目标易混淆信号的挑战。
