- Abstract
Objective: To explore the characteristics of assessing the level of grit of self and others among military medical university students and the EEG characteristics of the evaluation process, and to provide theoretical basis and objective indicators for the comprehensive and objective evaluation of the individual's grit. Methods: The construction of Implicit Association-Grit test using E-Prime2.0 program, which is based on Implicit Association Test paradigm. 100 military medical university students (effective subjects were 90) were measured by the Grit O scale. Participants with high and low grit groups (20 each) were selected for Implicit Association-Grit Test, and EEG was recorded. The implicit effects and main EEG components of the two groups were analyzed. Results: The IAT D effect was calculated, independent t-test showed a significant difference between high grit group (0.55± 0.36) and low grit group (0.87± 0.49), t=-2.257,P<0.05, Cohen's d=0.74. Significant N400 and LPP were induced in both groups. In high grit group, for the N400 component, there were significant main effects for both the condition, F(1,17) =8.528, P<0.05, η²=0.334, and the site, F(10,170)=8. 207, P<0.001, η²=0.326, and for the LPP component, there were also significant main effects for both the condition, F(1,17)=5.471, P<0.05, η²=0.243 and the sites, F (10,170)=18.479, P<0.001, η²=0.521. In low grit group, for the N400 component, there were significant main effects for both the condition, F(1,17)=10.051, P<0.05, η²=0.372, and the site, F(10,170)=8.223, P<0.001 η²=0.326, while for the LPP component there was no significant main effect for the condition. Conclusion: 1.The implicit effect of military medical university students' evaluation of grit is significant, that is, he/she tends to think that the level of grit of self is higher than others. The implicit effect of grit evaluation should be considered when assessing grit by questionnaire. 2. The N400 and LPP components in implicit grit evaluation between the high and low grit military medical university students are different. N400 can be used as a judgment indicator for the degree of accuracy of the implicit grit evaluation. 3. Implicit effect and N400 component can be used as objective indicators for grit evaluation of military medical university students.
