Facial Expression Recognition And Deception Detection For College Students With High And Low Autistic Traits

Purpose: Autism Spectrum Disorder(ASD)is a pervasive neurodevelopmental disorder with abnormal social interaction patterns,narrow interests,and repetitive stereotypic behaviors as core symptoms,and a collection of core symptoms known to researchers as Autistic Traits(AT),a trait that is thought to be widely distributed in the population.The study suggests that there may be a problem with the Theory of Mind(To M)of autistic individuals,which is closely related to facial expression recognition and deception detection,and therefore the experiment was conducted to verify whether there are differences in facial expression recognition and deception detection between individuals with high and low Autistic Traits scores.Methods: First,students enrolled in Jiangxi University of Traditional Chinese Medicine were screened by the Autism-Spectrum Quotient(AQ)questionnaire,and the top10% of scores were selected as the high group and the bottom 10% as the low group.Study 1 measured the macro-expression recognition and micro-expression recognition ability of two groups of subjects by E-prime equipment,and Study 2 used an eyemovement instrument to explore the gaze preference of two groups of subjects for social and non-social still pictures and the deception detection ability of micro-expression segments and descriptive segments.Results: Study 1 found that there was a difference in facial expression recognition between the high and low AQ groups,with a significant difference in correct macroexpression recognition between the high and low AQ groups(t=2.565,p=0.013),but no significant difference in correct micro-expression recognition between the two(t=1.918,p=0.059).In the second gaze preference task,it was found that the low AQ subgroup had more gaze points(t=-2.437,p=0.018)and longer gaze time(t=-3.119,p=0.424)for social stimuli compared to non-social materials.This difference was not found in the high AQ score subgroup.In the second deception detection task,the difference in correctness between the high and low AQ subgroups was found to be insignificant in the deception detection task with micro-expression segments(t=0.853,p=0.397)and in the deception detection task with descriptive segments(t=-0.087,p=0.931).Conclusion: Individuals with high and low autistic traits differed in facial expression recognition and did not differ in deception detection ability.High autistic trait college students had better performance on macro-expression recognition,indicating that the amount of autistic trait was related to the correct macro-expression recognition rate.The absence of gaze preference for social stimuli among high autistic trait college students verifies the existence of similar gaze patterns between high autistic trait groups and individuals with autism spectrum disorders,which provides a reference for conducting clinical research on individuals with autism spectrum disorders.
