在许多认知理论中，研究人员提出工作记忆和感知是交互作用的。例如，在以前的研究中，研究人员认为，与工作记忆内容相匹配的感觉输入在竞争加工资源时会有自动优势。作者测试了这一假设，要求观察者进行视觉搜索任务，同时保持视觉工作记忆中的对象表征。工作记忆激活产生一个简单但不可控的偏置信号的假设导致了与工作记忆内容相匹配的项目会自动捕获注意的预测。然而，没有证据表明自动注意力捕获;相反，参与者避免关注这些项目。因此，工作记忆的内容可以以灵活的方式用于促进或抑制加工。
In many theories of cognition, researchers propose that working memory and perception operate interactively. For example, in previous studies researchers have suggested that sensory inputs matching the contents of working memory will have an automatic advantage in the competition for processing resources. The authors tested this hypothesis by requiring observers to perform a visual search task while concurrently maintaining object representations in visual working memory. The hypothesis that working memory activation produces a simple but uncontrollable bias signal leads to the prediction that items matching the contents of working memory will automatically capture attention. However, no evidence for automatic attentional capture was obtained; instead, the participants avoided attending to these items. Thus, the contents of working memory can be used in a flexible manner for facilitation or inhibition of processing.
