A study on the affective cognition of first-level relatives of children with autism spectrum disorder based on the eye movement-face emotion recognition paradigm
Objective To investigate the affective and cognitive characteristics of first-degree relatives of children with autism spectrum disorder(ASD)to reveal the familial impact of ASD.Methods We recruited 33 first-degree relatives of children with ASD and 32 first-degree relatives of typically developing(TD)chil-dren.Participants completed the Interpersonal Response Indicator(IR1),the Toronto Alexithymia Scale(TAS-20),and an eye-tracking face emotion recognition task.Results ① Both the first-degree relatives of ASD children and those of TD children had higher correct recognition frequencies for the"surprised"emotional face.Additionally,the first-degree relatives of TD children were more likely to recognize the"sad"face.How-ever,there was no significant difference in response accuracy for the eye movement-face emotion recognition task between the two groups;②Compared with the first-degree relatives of TD children,first-degree relatives of ASD children scored lower on viewpoint-taking and higher on personal grief;③The extroverted thinking scores of first-degree relatives of ASD children were negatively correlated with empathy ability,imagination a-bility,viewpoint-taking,and empathetic attention.Conversely,personal grief scores were positively correlated with alexithymia.Conclusion There are discernible differences in the ability of first-degree relatives of chil-dren with ASD to discriminate specific negative emotions.Personal sadness is associated with emotional dis-cernment,and emotional type can affect the ability of first-degree relatives of children with ASD and TD to rec-ognize emotional faces.
