Abstract

Objective To explore the visual cognitive characteristics in children with learning disability(LD). Methods Participants included 42 children with LD and 37 control cases.All children had accepted WISC-R,the ability of visual distinguish,visual-motor integration test and were tested by PRVEP at five levels of spatial frequency.Results The mean scores of VIQ,PIQ and FIQ of children with LD were poorer than those of controls(P<0.01).Moreover,the poor ability of coding in children with LD had significantly 37% difference with the control.The mean scores of VMI in LD group and controls were 93±16,115±16,respectively.The visual distinguish error rate of LD group was greater than that of controls(P<0.001).The latencies of P100 at all five spatial frequencies were significantly prolonged in the LD group than in the normal children. Conclusion LD children with average cognition capability still have poorer visual perception compared with the normal children.Detection specific visual perceptual in many aspects in children with LD could provide specific rehabilitative strategies.
