Autistic Children’ S Identification Of Threat Information Of Different Intensity

In the study of children with autism,the research of threat identification has aroused general concern.It is well-known that young children with autism have substantially complete physiological identification framework of threat.Based on this,the present study is to explore the characteristics about autistic children’s threat identification.In order to verify that the strength of threat information will influence both normal and autistic children’s identification of threat information,the study tests both normal and autistic children’ s reaction to threat information with different strength which is compartmentalized into phylogeny and ontogeny.Experiment 1: Discussion the difference of the influence of phylogenetic threat information on normal and autistic children’s identification of threat.Using 2(group: normal vs.autism)× 2(threat strength: high-threat snake vs.low-threat snake)two-factor mixed design.The results show that both normal and autistic children have much shorter time reaction to snakes with high-threat than to that with low-threat and it is the time that normal and autistic children used to react to is remarkably distinct.Experiment 2: Discussion the difference of the influence of ontogenetic threat information on normal and autistic children’s identification of threat.Using 2(group: normal vs.autism)× 2(threat strength: high-threat syringe injector vs.low-threat syringe injector)two-factor mixed design.The results show that both normal and autistic children have much shorter time reaction to syringe injector with high-threat than that with low-threat and it is also the time that normal and autistic children used to react to is significantly different.Experiment 3: Discussion the difference of the influence of phylogenetic threat information on normal and autistic children’s identification of threat.Using 2(group: normal vs.autism)× 2(threat level: high-threat angry face vs.low-threat angry face)two-factor mixed design.The results show that both normal and autistic children have much shorter time reaction to angry face with high-threat than that with low-threat and it is still the time that normal and autistic children used to react to is totally different.
