Cognitive information processing characteristics of children with autism spectrum disorder / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To evaluate the cognitive information processes in children with autism spectrum disorder(ASD)based on the Das-Naglieri Cognitive Assessment System(DN: CAS)and to explore the characteristics of these cognitive processes.Methods:Thirty-two children with ASD and thirty-two healthy controls matched 1∶1 by gender and age were enrolled in this study.The cognition of all individuals was evaluated by the DN: CAS.SPSS 26.0 software was used for statistical analysis and Mann-Whitney U test was conducted to analyze the data. Results:Compared with the healthy control group, children with ASD had significantly lower scores in planning subtest of DN: CAS(23.50(19.00, 25.00) vs 30.50(27.00, 35.75), Z=-5.014, P<0.01), attention subtest of DN: CAS(25.50(20.25, 27.75) vs 33.00(28.00, 36.00), Z=-4.317, P<0.01), and the DN: CAS total score(115.00(106.00, 132.25) vs 139.00(127.00, 143.00), Z=-3.849, P<0.01). And there were significant differences in matching numbers(9.00(6.25, 10.00) vs 12.00(10.00, 13.75), Z=-4.317, P<0.01), planned codes(7.00(5.25, 8.00) vs 9.00(7.00, 11.00), Z=-3.404, P<0.01), planned connections(7.00(4.25, 9.75) vs 10.00(9.00, 12.00), Z=-4.383, P<0.01)in planning and expressive attention(8.00(6.25, 10.75) vs 11.50(8.25, 13.75), Z=-3.251, P<0.01), number detection(8.00(6.25, 10.00) vs 10.00(9.00, 12.00), Z=-3.628, P<0.01), receptive attention(8.00(6.00, 9.00) vs 10.00(9.00, 13.00), Z=-3.351, P<0.01)in attention between ASD children and healthy controls. Conclusion:ASD children have the planning and attention deficits.
