This study is a 6-week open-label clinical trial involving 20 children aged 6-10 years with autism spectrum disorder. During the study, subjects received repeated transcranial magnetic stimulation（rTMS）intervention at the left primary motor cortex (M1) 5 times per day for 10 days. From the beginning of intervention to the end of 4 weeks after the completion of intervention, the subjects's clinical symptomatology, cognitive psychology, neuroimaging, and adverse events will be followed up.Our purpose is to explore whether rTMS can improve the clinical symptoms of children with autism spectrum disorder in China, and to explore the neurophysiological mechanism of rTMS for autistic children.
Participants will receive continuous theta burst stimulation (cTBS) for a 10-day period (10 sessions). If feasible for the participant, all stimulation sessions will be held at the same time of the day. During this study，participants' clinical symptomatology, cognitive psychology, neuroimaging, and adverse events will be followed up for four times, specifically，before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention.

| Social Response Scale (SRS) | SRS is a questionnaire used to assess the presence and severity of social impairment, with high scores indicating severe symptoms. Change of the SRS from baseline to 3 month after treatment to evaluate the effect of computer social interaction treatment on ASD children. | Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |

| Repetitive Stereotyped Behavior - Revised (RBS-R) | The Repetitive Behaviors Scale - Revised (RBS-R) is a 44-item self-report questionnaire that is used to measure the breadth of repetitive behavior in children, adolescents, and adults with Autism Spectrum disorders. The RBS-R provides a quantitative, continuous measure of the full spectrum of repetitive behaviors. The RBS-R consists of six subscales including: Stereotyped Behavior, Self-injurious Behavior, Compulsive Behavior, Routine Behavior, Sameness Behavior, and Restricted Behavior, that have no overlap of item content. |

| Cambridge Neuropsychological Test Automated Battery (CANTAB) | CANTAB tests have demonstrated sensitivity to detecting changes in neuropsychological performance and include tests of working memory, learning and executive function; visual, verbal and episodic memory; attention, information processing and reaction time; social and emotion recognition, decision making and response control. | Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |

| Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
| ADHD Rating Scale | ADHD Rating Scale is the most widely used ADHD screening and treatment monitoring tools. | Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
| Behavior Rating Inventory of Executive Function(BRIEF) | Specifically the investigators will evaluate the changes in executive function (EF) scores before and after cTBS treatment. The higer scores indicate more impairment in executive function. | Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
| Childhood Autism Rating Scale (CARS) | CARS is a behaviour-rating scale used to assess the presence and severity of the symptoms of autism spectrum disorder(ASD), with scores ranging from 15 to 60 and high scores indicating severe symptoms. Change of the CARS from baseline to 3 months after treatment to evaluate the effect of tablet computer social interaction treatment on ASD children. | Before intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
| Clinical Efficacy Rating Scale (CGI) | CGI is a scale used to assess the severity of the illness and the global improvement of the patient under intervention. | 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
| Continuous Operation Test (CPT) | To obtain reliable parameters of behavior, continuous performance tasks (CPTs) are usually used where the subject performs a constant-difficulty task for minutes or tens of minutes without interruptions. | Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
| Resting State Electroencephalography | There are three main parameters: phase locking value(PLV) , coherence (Coh) and the power spectral density of alpha band (PSD). PLV and Coh are estimated for exploring the functional connectivity between the targeted brain region and the rest regions of brain. | Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
| Functional Near Infrared Spectroscopy , fNIRS | Head fNIRs is a non-invasive, non-ionizing method for measuring and imaging the functional hemodynamic response to brain activity. It measures changes in hemoglobin (Hb) concentrations within the brain by means of the characteristic absorption spectra of Hb in the near-infrared range. Changes in the head fNIRs results of the subject before and after treatment. | Before intervention, 5 days after intervention, immediately after the completion of intervention , and 4 weeks after the completion of intervention |
