Abstract:
Objective To explore the delayed discount and personality characteristics of impulsive and premeditated male prisoners and their correlation.Methods A total of 120 male prisoners with aggressive behaviors were tested by Self-made General Situation Questionnaire,Impulsive / Premeditated Aggression Scale (IPAS),NEO Five-Factor Inventory (NEO-FFI),Delay Discount Task (DDT).The effective participants were ninety,including 51 in impulsive group and 39 in premeditated group.Analyzed the difference of delayed discount and personality characteristics between the two group.Results (1) In the delayed discount task,the delay discount rat (K) of the impulsive violence group (0.0278 ± 0.0555) was significantly higher than that of the premeditated violence group (0.0042±0.0078).The difference was statistically significant (t=3.004,P =0.004).(2) The scores of agreeableness (35.84 ± 4.08) and conscientiousness (37.04±4.83) in impulsive violence group were lower than that in premeditated violence group(38.46±5.53,42.31±5.96),and the difference was statistically significant (t=-2.587,P=0.011;t =-4.634,P＜0.01).(3) Correlation analysis showed that K value was not significantly correlated with all dimensions of the big five personality(P＞0.05).Conclusion Male impulsive prisoners have faster tendency to delay discounting compared with male premeditated prisoners.Lower agreeableness and conscientiousness are the personality characteristics of male impulsive prisoners.
