Abstract: Objective To compare the difference in contingency discrimination training between children with autism spectrum disorder (ASD) and normal children, in order to provide suggestions for the intervention of ASD children. Methods A total of 22 children diagnosed with ASD in the Department of Children's Health Care of Shanghai Children's Hospital and 24 normal children matched with age and intelligence quotient (IQ) were selected into this study from July 2020 to October 2021. Children in both groups took contingency discrimination training, and the difference was compared. Results The score of positive and negative contingency discrimination training under motivational manipulation between ASD children and normal children had no significant difference (Z=1.35,1.63, P＞0.05). ASD children scored significantly lower in positive and negative contingency discrimination training with external visualization signs than normal children (Z=2.83, 5.04, P＜0.05). And for ASD children, the score of positive contingency discrimination training with external visualization signs was significantly different with that of negative contingency discrimination training with external visualization signs (Z=3.17, P＜0.05). Conclusion ASD children have lower contingency discrimination training with external visualization signs than normal children. In addition, ASD children have lower negative contingency discrimination training with external visualization signs than positive contingency discrimination training with external visualization signs. Therefore, it is recommended that training related to contingency discrimination training with external visualization signs should be added to the rehabilitation training of ASD children.
