An Eye Movement Study On The Diachronic Transform Of Children With Autistic Spectrum Disorders

From the perspective of breadth,diachronic transformation makes people's thinking not limited by the current material,and can restructure the past and expect the future from the current state.In depth,diachronic transformation enables us not only to use current factors to understand the real world,but also to explain the state from the process of development and change that can not be directly observed.Children with autism spectrum disorder(hereinafter referred to as autistic children)lack of time cognitive ability,resulting in their lack of intuitive sense of time,and it is difficult to understand the current state of things longitudinally.This makes it difficult for them to anticipate the future and adapt to the development and change of things,thus showing a higher level of anxiety and more challenging behavior.Previous studies have focused on the low level of time perception in autistic children,such as time series perception and time distance perception.Although foreign researchers represented by the Montangero team have carried out a more in-depth exploration,their research subjects are mostly typically developing children,less autistic children.This study compares the performance of diachronic switching ability between autistic children and typically developing children through experiments,and describes the development status,characteristics and influencing factors of diachronic switching in autistic children,so as to provide more appropriate diagnosis,assessment and educational rehabilitation for them.The study included four experiments: the characteristics and influencing factors of diachronic transition in autistic children were explored from four aspects: biological categories,background cues,duration and time orientation.The diachronic conversion ability of children was investigated by picture selection method.The results showed that: 1.Children with autism have a certain diachronic transform ability,and their scoring rate in the diachronic transform task reaches 57.5%;2.The diachronic transform ability of autistic children is affected by biological sub-category,background prompts and time interval;3.The first entry time,fixation time and the number of fixations of autistic children's diurnal conversion thinking are affected by the biological sub-category;4.The background prompts have little effect on the first entry time,fixation time and fixation times of the autistic children's diurnal conversion;5.The time interval affects the eye movement data of autistic children and typically developing children.6.Different time orientations have different effects on the first entry time and the number of fixations of autistic children and typically developing children;7.Time orientation affects autism The diachronic transform task scores of children with severe illness and typically developing children have no effect.conclusions:1.Children with autism have certain diachronic thinking skills,but they are inadequate compared with typically developing children;2.There are relatively rigid and sequential biases in the diachronic transform of autistic children,and the eye movement characteristics of atypical gaze are prominent;3.The diachronic transform thinking of children with autism is significantly affected by the biological category,background prompts and time interval.It is recommended to enrich the evidence-based materials for clinical intervention.
