Abstract：Objective To explore the intervention effect of transcranial direct current stimulation(tDCS)combined with n-back task on attentional blink(AB).Methods tDCS and 2-back task of space were used to intervene the AB performance of 60 male college students in an Air Force academy for 4 weeks,and the effects of the intervention were tested based on behavioral data and functional near-infrared spectroscopy(fNIRS).Results First,2-back task of space alone did not improve AB performance.Second,stimulating the left dorsal lateral prefrontal cortex(DLPFC)of the subjects with tDCS alone resulted in a certain degree of improvement in AB performance.Third,the combination of 2-back task of space and tDCS to stimulate the left DLPFC of the subjects achieved a more obvious intervention effect than tDCS alone.Fourth,the data of fNIRS showed that after the combined intervention,the mean oxygenated hemoglobin concentration in the left DLPFC region of the subjects increased significantly before AB task,while there was no significant change in the tDCS group and 2-back task of space group.Conclusion The combination of tDCS and n-back task can improve AB performance effectively,providing important technical references for improving AB of military pilots and other groups.
