Abstract:
Objective To investigate the characteristic of top-down attentional control of acute stress disorder children.Methods According to SCID-IV-TR,23 acute stress disorder children were chosen as the experinent group and 23 normal children were chosen as the control group.They were asked to perform a visual search task.Results (1) The reaction time of acute stress disorder children((1 253±158)ms) was significantly longer than normal children's((1 194± 146) ms) (P＜0.05).(2) The reaction time of valid condition((1 172± 144) ms)was significantly shorter than neutral condition ((1 229± 156) ms) and invalid condition ((1 269± 157) ms) (P＜0.05),there was no difference of reaction time between neutral condition((1 229± 156)ms) and invalid condition ((1 269±157)ms) (P＞0.05).(3) The reaction time of simple display condition((1 182±127)ms) was significantlv shorter than complex display condition ((1 264± 177)ms) (P＜0.01).Conclusion The performance of acute stress disorder children on top-down attentional control is less than normal children,the reason is that inhibiting capacity of acute stress disorder children is lower than normal children.It indicates that trauma event have negative influence on children's inhibiting capacity.
