| Autism spectrum disorder(Autism Spectrum Disorder,ASD)is a generalized neurodevelopmental disorder,among which autism is the most serious.Its main core symptoms are abnormal social behavior,repeated stereotype behavior,narrow range of interest and so on.Among them,the abnormal social behavior is manifested in the impairment of social communication ability,emotional understanding,emotional expression defects,therefore,the problem of emotional disorders of autistic people has become a hot topic at home and abroad for several years.As a basic human skill,emotion recognition ability plays a very important role in interpersonal communication and daily life.Emotional recognition(Emotion Recognition)refers to the process of speculating and judging individual emotions by observing facial expressions,pronunciation and intonation,body movements,etc.Previous studies have shown that facial expression is the main carrier of emotional information and can transmit more emotional information.New research has found that facial expressions and body expressions do not exist alone with each other.When face expressions and body movements are presented at the same time,body expressions play a more important role in emotional cognition.It can even change the emotional category of facial expressions.Therefore,in recent years,the study of emotional disorders in autistic people has become a hot topic in the field of psychology,but there are few intervention studies on improving the recognition of somatic expressions in autistic people.In this study,the emotion priming paradigm was used to explore the ability of music emotion recognition and body expression recognition in autistic people and the influence of different types of music on the body expression of autistic people.To understand the usability of this paradigm in improving the body expression recognition of autistic people.this study consisted of 3 behavioral experiments,all of which were designed using a two-factor mixed experiment.the independent variables were group(experimental group,control group)and emotional consistency(consistent,inconsistent).the dependent variables were the correct rate of emotion recognition and response time.Experiment 1 used chords as priming stimuli and target stimuli to explore the ability of music emotion recognition in autistic people through single channel emotion priming paradigm.this experiment was designed with 2(group: experimental group,control group)*2(music mood consistency: consistent,inconsistent)two-factor mixing experiment.Among them,the group is the inter-subject variable,and the music emotion consistency is the intra-subject variable.The dependent variable is the response time and correct rate of music emotion recognition.The results showed that :(1)In terms of correct rate,the main effect of emotion consistency,the main effect of group and the interaction effect of group and emotion consistency were not significant.(2)In terms of response time,the main effect of the group was significant,the response of the autistic group was higher than that of the control group,the main effect of emotional consistency was significant,that is,the response of the two groups under the same conditions was significantly higher than that of the inconsistent conditions,and the interaction effect of group and emotional consistency was not significant.In experiment 2,the single channel emotion priming paradigm was used,and the experimental material was changed to the body expression picture to explore the ability of the autistic body expression recognition.this experiment was designed with 2(group: experimental group,control group)*2(emotional consistency: consistent,inconsistent)two-factor mixed experiment design.The group was the inter-subject variable and the emotional consistency was the intra-subject variable.The dependent variable is the response time and correct rate of somatic expression recognition.The results showed that :(1)the main effect of the group was significant,the correct rate of the control group was significantly higher than that of the autistic group,the main effect of emotional consistency was not significant,the interaction effect of emotional consistency and group was significant.(2)In terms of response time,the main effect of the group was significant,the response time of the autistic group was higher than that of the normal group,and the main effect of emotional consistency was significant,that is,the response time under the consistent condition was shorter than that of the inconsistent condition.The interaction between group and emotional consistency was significant.Simple effect analysis showed that in the control group,the response time under emotional consistency was significantly shorter than that in autistic group.There was no significant difference between emotional consistency and emotional inconsistency;other simple effects were not significant.In experiment 3,the cross-channel music emotion priming paradigm was adopted,the music chord was used as the priming stimulus,and the body expression picture was used as the target stimulus to explore the influence of music emotion on the body expression recognition.In this experiment,2(group: experimental group,control group)*2(emotional consistency: consistent,inconsistent)two factors mixed experimental design.The group was the inter-subject variable and the emotional consistency was the intra-subject variable.The dependent variable is the response time and correct rate of somatic expression recognition.The results showed that :(1)in terms of accuracy,the main effect of the group was not significant,the correct rate of the control group was higher than that of the autistic group,and the main effect of emotional consistency was significant.The interaction effect between group and emotion consistency was not significant.(2)In terms of response time,the main effect of the group was significant,the response time of the autistic group was significantly higher than that of the control group,and the main effect of emotional consistency was significant,that is,the response time of the two groups under consistent conditions was shorter than that under inconsistent conditions,and the interaction effect between group and emotional consistency was not significant.The experimental results show that the musical emotion recognition ability of autistic people is not significantly different from that of normal people,the body expression recognition ability is defective,and the musical emotion has an emotional priming effect on the body expression.When musical emotions are consistent with body expressions,autistic people have higher accuracy and faster response.The results of this study can provide some empirical basis and reference for the intervention of improving the somatic expression ability of autistic people.
