工作记忆是通过保持相关信息的优先级来减少分心的关键，这一假设在人类的神经成像和心理实验中得到了验证。参与者进行了一项选择性注意任务，要求他们忽略分心的面孔，同时在工作记忆中保持一系列数字，这些数字在每次试验中顺序相同（低记忆负荷）或顺序不同（大腿记忆负荷）。更高的记忆负荷，与前额叶活动的增加，导致更大的干扰效果的行为表现，从分心的面孔，加上增加面部相关的活动在视觉皮层。这些发现证实了工作记忆在视觉选择性注意控制中的重要作用。
The hypothesis that working memory is crucial for reducing distraction by maintaining the prioritization of relevant information was tested in neuroimaging and psychological experiments with humans. Participants performed a selective attention task that required them to ignore distracter faces while holding in working memory a sequence of digits that were in the same order (Low memory Load) or a different order thigh memory Load) on every trial. Higher memory Load, associated with increased prefrontal activity, resulted in greater interference effects on behavioral performance from the distracter faces, plus increased face-related activity in the visual cortex. These findings confirm a major role for working memory in the control of visual selective attention.
