    AbstractPast 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.Copyright © 2014 IBRO. Published by Elsevier Ltd. All rights reserved.
