Recent studies have proposed that a common mechanism may underlie spatial attention and spatial working memory. One proposal is that spatial working memory is maintained by attention-based rehearsal [Awh, E., Jonides, J., & Reuter-Lorenz, P. A. (1998). Rehearsal in spatial working memory. Journal of Experimental Psychology: Human Perception and Performance, 24(3), 780-790], and so a spatial attention shift during the retention interval of a spatial location should impair its memory performance. In the present study, participants engaged in single-item, parallel or serial search tasks while remembering a spatial location. Although memory tended to bias all searches, the need for an attentional shift during the retention interval impaired memory performance only in single-item search, but not in other searches. These findings suggest that previous evidence for the attention-based rehearsal account does not generalize to visual search. Results are discussed with regard to the relationship between spatial attention and spatial working memory.
最近的研究表明，空间注意力和空间工作记忆可能存在共同的机制。一种观点认为，空间工作记忆是通过基于注意力的复述来维持的[Awh, E., Jonides, J., & Reuter-Lorenz, P. A. (1998). 空间工作记忆中的复述。《实验心理学杂志：人类感知与表现》，24(3)，780 - 790]，因此在空间位置的保持间隔期间进行空间注意力转移应该会损害其记忆表现。在本研究中，参与者在记住一个空间位置的同时进行单项、平行或串行搜索任务。尽管记忆倾向于使所有搜索产生偏差，但在保持间隔期间进行注意力转移的需求仅在单项搜索中损害了记忆表现，而在其他搜索中则没有。这些发现表明，先前基于注意力复述理论的证据并不能推广到视觉搜索。本文就空间注意力与空间工作记忆之间的关系对研究结果进行了讨论。
