The subscores inemotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglectof CTQ were significantly higher than those in the control group.(P<0.01).Comparedwith normal controls, patients had significantly lower total accuracy（（86.74±6.16vs73.42±11.86）%, P<0.01) and longer total reaction time（（2776.75±703.42vs4321.40±956.83）ms, P<0.01) of EBEDT. The significantdifference were also found on the accuracy and reaction time of the EBEDT sixbasic emotion between the two groups (P<0.01). Correlation analysis indicated thatCTQ total score were negatively correlated with the EBEDT total accuracy(r=-0.390,P<0.01), and its sub-accuracy of happiness, surprise，sadness, and anger (respectivelyr=-0.419, r=-0.451, r=-0.391, r=-0.344，P<0.01) in the patients group. The correlationbetween CTQ total score and EBEDT total accuracy was also found in the controlgroup.Conclusion Childhood trauma is related to eye basic emotion recognition inschizophrenia patients, suggesting that the trauma during childhood can affect thesocial recognition ability when adault.
