Abstract
According to the Simple View of Reading, reading ability can be divided into decoding and language comprehension. In the present study, decoding and comprehension's contribution to reading ability was studied both in children with reading difficulties and in children with typical reading ability. Decoding and comprehension was further divided into sub-components, and the contribution from non-verbal ability and general processing speed was also studied. The results demonstrated that decoding made the largest contribution to reading ability for children with reading difficulties, while language comprehension contributed the most for children with typical reading ability. The contribution of non-verbal ability was not significant, and general processing speed only made a significant contribution to decoding for typical children. The two factors in the Simple View of Reading, decoding and comprehension, together explained less of the variance in reading ability for children with reading difficulties than for children with typical reading ability.
