过去的研究表明，场依赖-独立性(FDI)可以影响学习成绩、选择性注意力和工作记忆。然而，FDI如何调节选择性注意和工作记忆的潜在机制仍然不清楚。利用事件相关电位(ERP)技术，特别是对侧延迟活动(CDA)，本研究发现，在2项和2项2-分心干扰条件下，场独立(FI)参与者的正确反应率和CDA幅度是相似的。场依赖(FD)受试者表现较差，当出现分心物时，CDA波幅增强。这些结果表明，与FD参与者相比，FI参与者能够更有效地过滤与任务无关的信息。FD和FI个体之间的主要区别在于它们的抑制功能。
Past research has demonstrated that field dependence–independence (FDI) can affect academic performance, selective attention, and working memory. However, the underlying mechanism of how FDI modulates selective attention and working memory is still unclear. Using event-related potential (ERP) techniques, specifically with the contralateral delay activity (CDA), the present study found that the correct response rates and CDA amplitudes in the 2-item and 2-item–2-distractor conditions were comparable for field independence (FI) participants. Field dependence (FD) participants performed worse, and the CDA amplitude was enhanced when distractors appeared. These results indicated that FI participants can filter out task-irrelevant information more efficiently than FD participants. The main difference between FD and FI individuals is their inhibition function.
