Selecting relevant information while ignoring irrelevant distractors is critical for every cognitive function. Visual working memory (VWM) load is 1 factor that can modulate attentional selection; however, previous studies yielded inconsistent results concerning whether VWM load increases or decreases attentional selection. In the current study, we manipulated VWM load while controlling the size of attentional zoom, which could have influenced distractor interference in prior studies. We found that increasing the size of attentional zoom resulted in greater distractor interference; however, increasing VWM load did not modulate attentional selection when attentional zoom was held narrow. The current findings suggest that the interaction between selective attention and VWM can be better understood by dissociating the size of attentional focus and VWM load.

选择相关信息而忽略不相关的干扰因素对于每种认知功能都至关重要。视觉工作记忆 (VWM) 负荷是调节注意力选择的 1 个因素；然而，之前的研究对于 VWM 负荷是否增加或减少注意力选择得出了不一致的结果。在当前的研究中，我们在控制注意力缩放大小的同时操纵 VWM 负荷，这可能会影响之前研究中的干扰物干扰。我们发现，增加注意力缩放的大小会导致更大的干扰物干扰；然而，当注意力聚焦狭窄时，增加 VWM 负荷并不会调节注意力选择。当前的研究结果表明，通过分离注意力焦点的大小和 VWM 负荷，可以更好地理解选择性注意和 VWM 之间的相互作用。
