Although spatial working memory has been shown to play a central role in manual IOR (Castel, Pratt, & Craik, 2003), it is so far unclear whether spatial working memory is involved in saccadic IOR. The present study sought to address this question by using a dual task paradigm, in which the participants performed an IOR task while keeping a set of locations in spatial working memory. While manual IOR was eliminated, saccadic IOR was not affected by spatial working memory load. These findings suggest that saccadic IOR does not rely on spatial working memory to process inhibitory tagging.
尽管空间工作记忆已被证明在手动IOR中起核心作用（Castel、Pratt和Craik，2003年），但到目前为止，尚不清楚空间工作记忆是否参与扫视IOR。本研究试图通过使用双重任务范式来解决这个问题，在该范式中，参与者在执行IOR任务的同时，在空间工作记忆中保留一组位置。虽然手动IOR被消除，但扫视IOR不受空间工作记忆负荷的影响。这些发现表明，扫视IOR不依赖空间工作记忆来处理抑制标记。
