Abstract：Objective To explore the effects of negative emotion on risky decision-making and inhibitory control in cadets of the military medical university.Methods A total of 124 medical students were recruited from a military medical university from April to July 2023,and based on the scores of the anxiety and depression dimensions of the symptom check list 90(SCL-90),subjects with scores in the top 27％of both dimensions were included in the low-negative emotion group(n=22),and subjects with scores in the bottom 27％were included in the high-negative emotion group(n=23).The Cambridge gamble task(CGT)and the Stroop colour word task were used to assess risky decision-making ability and inhibitory control functions in the two groups of subjects respectively.Results In terms of risky decision-making,the quality of decision-making in the high-negative emotion group was lower than that in the low-negative emotion group,and the time of decision-making was greater than that in the low-negative emotion group,and the differences between the two groups were statistically significant(t=3.505 and-2.410 respectively,all P＜0.05);there was no statistically signifi-cant difference between the two groups in terms of risk regulation(Z=-1.794,P＞0.05).In terms of inhibitory con-trol,the rate of correctness on the paradoxical task and the rate of correctness on the non-paradoxical task in the high-negative emotion group were lower than those in the low-negative emotion group,and the differences between the two groups were statistically significant(t=2.187 and 2.093 respectively,all P＜0.05);there was no statistical difference between the two groups in terms of the mean reaction time on the paradoxical task and the mean reaction time on the non-paradoxical task(t=1.222 and 1.288 respectively,all P＞0.05).Conclusion Although not yet reaching diagnostic cri-teria for mood disorders,high negative emotion can also impair risky decision-making and inhibitory control in cadets of the military medical university.
