Category Representation Of Adolescents With Different Levels Of Subthreshold Autism Traits In Visual Spatial Working Memory

This study investigated whether individuals at different levels of sub-threshold autistic traits were impaired in the use of visual spatial working memory or semantic systems,especially in the classification process affected by working memory.The experimental task adopted by the study was an "identical-different" task adapted from Lachmann and Geissler(2002).The subjects were divided into three groups according to the autistic traits,namely the high autism trait group,the middle autism trait group,and the low self.Closed trait group.All participants need to complete the"same-different" task composed of the physical feature task and the classification feature task.In the classification feature task,when the two images presented successively belong to the same equivalence set,that is,the same shape Different images must be judged to be the same.In the physical feature task,only the images that are identical in shape and direction are judged to be the same,and in other cases,they are judged to be different.This experiment assumes that the classification process is defective in the subjects of the high autism trait group,then the ESS effect is not exhibited,and there is no response conflict in the physical feature task.However,the experimental results showed that the subjects in different autistic traits showed the ESS effect,and they all showed response conflicts in the physical feature task.Therefore,the ability of the high autism trait group to be classified and characterized is consistent with the middle autistic trait group.However,there is a significant main effect in the reaction,that is,the high autism trait group is significantly higher than the middle and low autism trait group.The final conclusion of this study is that the mechanisms of classification coding for high-and low-autistic traits and middle-adjuvant traits are the same.
