In order to understand the characteristics of facial expression recognition of children with autism，The research group selected 32 children with autism as the experimental group， 31 ordinary children 4-6 -year -old children as control group。Use real people and cartoon facial expressions as stimulating materials，Each contains 10 happiness、Calm、Sad facial expression picture。With the help of Germany's SMI Red250MOBILE portable eye movement，Use 2 (group: ordinary children、Children in autism) × 2 (Picture type: real person、Cartoon) × 2 (Interesting Area: Mouth、Eyes) × 3 (Facial Emoticon Type: Happy、Calm、Sad) hybrid experiment design。The first gaze time for the entire picture of the two groups of children、Average gaze time、Number of gaze points，and Eye、The first view time in the two interest areas of the mouth、Average gaze time、Data from the number of gaze points for collection and analysis，It is found that children with autism compare with ordinary children，Difficulty of facial expression recognition。

Activ Spectrum Disorder，ASD)，Is a social obstacle、Limited repeated behavior、Interest or activity is a neurological disorder with the main characteristics。Discovery of previous studies，Children with autism have obvious damage in terms of emotional understanding，Children in Lonely are understanding pride、embarrassment and bet365 Play online games other expressions is more difficult，This may be related to its mental interpretation ability and compensation strategy。Jiao Qing pointed out，Children with autism can understand the positive of others、negative emotions，But it is difficult to understand the recognition of false beliefs。As one of the external performance of emotional activity，Facial expressions have a large extent adaptation to pass emotions、communication and other functions，It is interpersonal communication、Interpersonal communication provides a set of efficient symbolic systems，so that the individual can accurately pass the emotions without the help of language。Facial Expression Recognition refers to when the facial expression is presented，Individual calling a certain cognition，The process of judging it。Researchers compare the facial expression recognition evaluation results of ordinary children and autism children，It is found that there are large differences in two types of children。Study found out，The time ratio and number of times and the number of times and the number of autism individuals are less than the non -core area，There is no significant difference between individuals，From the perspective of the specific viewing site，They look at the mouth more than the eyes。Chen Shunsen pointed out，Children with autism to watch facial expressions are shorter than ordinary children，Specifically，The short view time for their eyes，Especially lack of spontaneous gaze bias for the left eye，But there is no significant difference between the viewing time of the mouth Bet365 lotto review and non -core area and the ordinary children。

　　The ability to detect facial expressions is not completely damaged

Research Discovery，In terms of the first view time，Children with autism, perceive Cartoon Sadness、The time for the calm face of the cartoon is greater than the sadness of real people、Real face calm face expression。This may be because compared with the facial expression of the real person，The information contained in the former is too little，Visual stimuli that can be given to children with autism is scarce，The information to be passed is not rich enough，Therefore, the attention of children who cannot attract autism，As a result, it leads to too long aware time。and real people sad、Live calm facial expressions are more common in daily life，It is easier to attract children's attention。other，Children with autism are being happy to be real people、Cartoon is not obvious when the facial expression is happy，It may be because compared with other facial expressions，Cartoon happy facial expression is more exaggerated，Close to the expression with real people，Therefore, there is no difference between the two。

On the number of gaze points，Children with autism are obviously less than ordinary children。This may be because children with autism have generated attention when observing facial expression pictures，And this phenomenon is automatically generated by perceive the facial expression，It is an automatic avoidance of emotional face。Whether this kind of avoidance has caused social communication obstacles of children with autism，It is necessary to conduct follow -up research。

Although the autism is less than ordinary children at the number of gaze bet365 live casino games points，But the difference between the two on the average gaze is not obvious。This may be because autism children will focus on the non -facial expressions on the screen，That is some blank areas，So there seems to be no difference in the average gaze time，but the number of gaze points is very different。This result also means that autism children are not processed in depth enough for facial expression pictures，This may also be the main reason for the low facial expression recognition rate。From the perspective of paying attention to resource allocation，Children with autism are more likely to allocate their attention resources for average allocation，This ensures that all areas can be processed。Visual Pay attention to the theory of zoom mirror pointed out，When the individual expands its visual attention range，The density of its psychological resources will be reduced，This affects the analysis and integration ability of local details。From the specific situation of facial expression recognition of children with autism，Although they adopted this average gaze mode，Get a lot of information from the entire picture，But because of their weak integration ability，There are still some difficulties in facial expression recognition。From this point of view，This average gaze mode also affects the processing and understanding of facial emoji information to a certain extent。Visible，Breakfast children's perception and processing real people、The ability of the cartoon facial expression is not completely damaged，It is not deep enough。

　　When watching facial expressions, we will focus more on the eyes

Research indicates，Ordinary bet365 best casino games individuals will notice eyes when watching facial expressions、mouth and other facial features，The longer the time of watching the eyes and mouth，The more social information that individuals can collect。Discovery in this study，Children with autism for the eyes、The viewing time of the mouth、The number of gaze points is less than ordinary children。Eye、The mouth is the two main parts of the information transmitted in the face，Due to the short gaze time of these two parts due to autism children，As a result, it cannot be deeply processed to the facial expressions presented，also so that they cannot from the eyes、Mouth and other parts to get more social information，Therefore, this may be the main cause of the difficulty of identifying facial expressions and causing their social obstacles。

Discovery of previous studies，Children with autism are lower than the time of gaze mouth，and this study draws the opposite conclusion。In this study，Similar children to children are similar to ordinary children，When watching three facial expressions, staying with the eyes more on the eyes，instead of mouth，This may be caused by the different research objects。Some researchers said，The lower the social communication ability of the individual，The shorter the time for its eyes to stare。Most of the predecessors are studied.，Their social emotions have developed and gradually improved，At the same time, their language has also gained better development。And the research objects of this study are mostly children with low age groups，Some even have no language expression，Social relationships are even less and less。So，Bet365 app download This conclusion may be closely related to the age and social development of the subject。Some researchers have pointed out，Children with autism have active attention to the eye area，But this kind of attention occurs on the basis of free observation，Once it is involved in emotional judgment、Complicated processing task，They will reduce the eyes of the eyes。Jin Li、Chen Shunsen pointed out，Let children with autism freely watch the calm expression，Children's gaze time for eyes is not different from ordinary children。So，Mission difficulty may be the key factor that leads to the avoiding eyes of autism children。and the three facial expressions selected by the Institute are relatively simple，Basically does not involve complicated processing of children，It is also more common in daily life。Of course，Whether it is due to the difficulty of the task, it affects the autism children for the eye、Differences in the eyes of the mouth，It needs further research。

In short，Children with autism can notice face -to -face emoji pictures，also has a certain facial expression processing ability，But I can't use this ability to identify facial expressions。The same as ordinary children，Children with autism when watching facial expression pictures，Most focuses on the eyes。So，Intervention training for facial expression recognition of autism children must be affirmed first，So as to carry out intervention training more targetedly。
