Abstract：Objective To compare the effects of high-definition transcranial direct current stimulation(HD-tDCS)combined or alone with radar cognitive training games on the performance improvement of radar operators,and to explore a more effective new training method for radar operators.Methods A total of 87 subjects were randomly divided into combination group(n =23),training group(n =22),stimulation group(n =21)and control group(n =21).HD-tDCS was used to continuously intervene the left dorsolateral prefrontal cortex of active radar operators for 9 d(once a day,20 min a time),and radar cognitive training games were performed simultaneously or separately.SPSS 26.0 software was used for two-factor repeated measures analysis of variance to compare the changes of working memory,attention,scores of radar cognitive training games and professional training scores in operators.Results All scores were not found to have significant main effect of group.The interaction effects between time and group were significant in ACC score of 2-back task(P =0.02),RT score of 4-back task(P<0.01),ACC score of 3D 1-back task(P = 0.06,marginally significant),RT score of memorization route(P<0.01),and RT score of double-batch route(P<0.01)in radar cognitive training games.The score of correct maximum value of working memory span task(P<0.01),RT score of 3-back task(P =0.04),ACC score of attention span task(P = 0.02),ACC score of psychomotor vigilance task(P<0.01),ACC score of memorization navigation point(P<0.01),RT score of memorization navigation point(P<0.01),ACC score of memorization route(P<0.01),ACC score of double-batch route(P<0.01),ACC score of multi-batch route(P<0.01),RT score of multi-batch route(P<0.01),and the score of calculating antenna pitch angle(P = 0.04)and reporting the distance and azimuth angle of navigation point(P<0.01)of the off-plane exercise of the radar operators were found to have significant main effect of time only.Conclusion Both HD-tDCS and radar cognitive training games can improve the performance level of operators.The former has a good application prospect in terms of safety and effectiveness,while the latter can be directly promoted and used after further optimization.
