The Effect Of Childhood Psychological Maltreatment On Inhibitory Control

Purposes: The main purpose of this study was to explore the inhibition control of the adults with childhood psychological maltreatment.Methods:(1)400 college students were selected randomly to complete the Child Psychological Maltreatment Scale.(2)According to the standard of Childhood Psychological Maltreatment Scale,24 students with childhood psychological maltreatment and 24 students without childhood psychological maltreatment were selected to take part in all experiments.(3)Experiment 1: Flanker task,2(groups)×2(types)mixed task,measured the feature on access of college students who suffered psychological maltreatment in childhood.(4)Experiment 2: visuospatial working memory task,2(groups)×2(types)mixed task.The aim was to find out the feature on deletion of college students who suffered psychological maltreatment in childhood..(5)Experiment 3: GO/NOGO task,single-factor completely random design,measured the feature on restraint of college students who suffered psychological maltreatment in childhood.Results:(1)In experiment 1: The reaction time was analyzed with Repeated Measurement ANOVA and the result showed that the main effects on task were significant(F=13.426,p=0.001).The number of mistakes was analyzed with Repeated Measurement ANOVA.The interaction between types and groups(F=4.435,p=0.041)was found.Further analysis showed that participants who experienced childhood psychological maltreatment had more mistakes in the consistent task than the control group.(2)In experiment 2: According to the result of Repeated Measurement ANOVA,the main effects on task(F=5.285,p=0.027)and the interaction between types and groups(F=5.656,p=0.022)were significant.Further analysis showed that participants who experienced childhood psychological maltreatment had lower score than the control group in ascending visuospatial working memory task.The deletion effect was analyzed with One-Way AVOVA.The deletion effect of the experimental group was significantly lower than the control group(F=5.656,p=0.022).(3)In experiment 3: The GO reaction time was analyzed with One-Way AVOVA,and the results showed that the childhood psychological maltreated individuals reacted more slowly than the control group(F=4.092,p=0.049).Conclusion: Childhood psychological maltreatment had a negative impact on access,deletion and restraint.College students who experienced psychological maltreatment in childhood were more easily to notice the interference information,influenced by proactive interference,and couldn’t inhibit prepotent response.
