Applying Somatosensory Interactive Technology To Assess Executive Function Of Children With Intellectual Disability: A Preliminary Study

The rise of somatosensory interaction technology has attracted researchers to explore the possibility of applying this technology to assess and intervent special children.At present,the evaluation methods of executive function are mainly based on scales and operational neuropsychological tests.They need to be further expanded.The first purpose of this study is to explore the effectiveness of the application of somatosensory interaction in the evaluation of executive function in children with intellectual disability.The second purpose is investigate the user experience and participation in the somatosensory interaction tasks.Therefore,the study use the somatosensory interactive tasks(Go/No go Task,Decoding Task,Stop Signal Task)and the traditional executive function tests(Stroop Color-word Test,Trail Making Test,Digit Span Task and Decoding Test)were assessed 73 intellectual disability children and 70 typically developing children of the same age.The study mainly assess inhibitory control,cognitive flexibility,working memory,attention,processing speed.The results are as follows:(1)The results of Somatosensory Go/No Go Task and Somatosensory Decoding Task in children with intellectual disability were significantly correlated with the results of traditional executive function test.The red light errors rate and the red light response of the Stop Signal Task were correlated with the results of traditional executive function test.Indicating that the tasks of somatosensory interaction can effectively evaluate executive function of children with significantly intellectual disability.(2)There was significant difference in the somatosensory interaction task between intellectual disability children and typical developing children.The somatosensory interaction task can be divided into the intellectual disability children and the typical developing children with good regional diversity.(3)There were no significant differences in executive function in the intellectual disability child's sex.There was significant difference in the hitting response time between mild intellectual disability and moderate intellectual disability.There were significant differences in the rate of red light error ? the number of correct decoding and the reaction time of decoding among children with intellectual disability at different ages.(4)The best sensitivity of Somatosensory Go/No Go Task is 69.9%,and its best specificity is 85.71%.The best sensitivity of Somatosensory Decoding Task is 74%,and its best specificity is 95.71%.The best sensitivity of Somatosensory Signal Task is 71.2%,and its best specificity is 71.4%.As a diagnostic tool for intellectual disability,somatosensory interaction task has certain accuracy,but it is not recommended alone and can be used in conjunction with other assessment tools.(5)The somatosensory interaction task has a good user experience and a higher participation.In conclusion,somatosensory interaction tasks have good calibration validity,high degree of division,good user experience and high participation.Therefore,they can be applied to evaluate the executive function of children with intellectual disability.
