title: Blurring the image does not help disabled readers.
abstract: Previous research has found that poor readers performed a visual search task more slowly than good readers, but that this difference was virtually eliminated by blurring of the search array. Whereas blurring had little effect on the performance of the good readers, it led to a dramatic improvement in the search rate of the poor readers. The present study set out to replicate this research with groups of 10-12 yr old disabled and average readers but with methodological improvements in the procedure and the analysis. It was found that the disabled readers performed the search task as well as the average readers, and that blurring of the display conferred no advantage on either group. The results are discussed in relation to the transient deficit theory of reading disability.
