Abstract： The filtering efficiency is the mechanism to inhibit irrelevant items from entering visual working memory, studies have shown that it can be measured through working memory capacity or representation precision. The neural processes underlie filtering efficiency are the presence of distractors, initiation of filtering, and filtering success/unnecessary storage, which are orchestrated by the prefrontal cortex and the basal ganglia, the posterior parietal cortex. The filtering efficiency’s changing directions are affected by age, mental/neurological disorders, emotions, cognitive characteristics et al. Future studies should further clarify the relationship between filtering efficiency and working memory capacity, identify the mental process of filtering efficiency, explore the brain mechanism of filtering efficiency among various groups, and improve the ecological validity of experimental paradigms.
