| 英文摘要 | Conclusion: The results suggest that ASD children have deficits in attentional and inhibitory control. Frontal dysfunction and weak ACC engagement in ASD were supported as the underlying neuronal inefficiency. Methods: 20 children with high-functioning ASD [Mean Age (SD): 10.75 years old (2.07 years); Mean IQ (SD): 101.4 (16.8)] and age- and IQ-matched normal children (NC) [Mean Age (SD): 9.80 years old (1.88 years); Mean IQ (SD): 110.7(17.8)] were investigated electrophysiologically during performance of a visual Go/NoGo task. An electrophysiological source localization method was employed to further analyze the data. Several different neurospsychological tests were also performed to provide behavioral measures on attention and inhibition. Objectives: To investigate neurophysiologic abnormalities in frontal and anterior cingulate cortex underlying attentional and inhibitory control in children with Autism Spectrum Disorder (ASD). Results: ASD children showed a significantly task-related lower frontal theta activity. This effect was associated with a significantly reduced activation of the anterior cingulate cortex (ACC). Both groups also differ significantly regarding the behavioral aspects of attention and inhibition. Leung, Shuk Yin Connie. "November 2009." Adviser: Chan Sue-Yin Agnes.
