摘要：AbstractAttention is an essential function for children's learning. Cancellation tasks are one of most popular tools used for the assessment of visuospatial attention. A computerized cancellation test system was developed to investigate whether the children with or without learning disabilities (LD) would have different performances on cancellation tasks. The result showed that group differences regarding task performance are all significant and independent from types of stimulus and layout. Post hoc analysis of between-group effects showed that the control group had more correct responses (F= 28.177,p< .001), and spent less time (F= 5.592,p= .021) than the LD group.
