摘要
采用Stroop色词作业,考察不同时间(21h、45h、69h)睡眠剥夺(sleep deprivation,SD)后抑制功能情况。结果发现,无论字色一致还是不一致,SD后作业成绩下降;同一组中,除SD21组错误数外,字色不一致成绩显著低于字色一致;正常对照组中字色不一致条件下晚正波LPC平均波幅大于字色一致条件;SD后ERP差异波(字色不一致同字色一致相减波)时潜期延长,波幅降低,并在SD45h后显著。表明睡眠剥夺后抑制能力降低,并在45小时后显著。
With the Stroop test, this study examined the inhibition ability aftersleep deprivation（SD） of different time（21h,45h, 69h）. The result showed that （ 1 ） In congruent and incongruent conditions, score declined after SD; （2）Except for the number of error of SIT21, scores in incongruent condition were lower than that in congruent condition in the same group. （3）Average amplitudes（500 - 800ms）of control in the incongruent condition were higher than in the congruent condition; （4）After SD, latency of difference wave of congruent and incongruent conditions of Strcop prolonged and the amplitude declined, especially significantly after SD45. So the inhibition ability declined after sleep deprivation, significantly after 45 hours.
