Jordan Left-Right Reversal Test: an analysis of visual reversals in children and significance for reading problems.

The Jordan Left-Right Reversal Test (JLRRT) was first published in 1974 (1) as a convenient measure of symbol reversals in children. A current revision of the test, based on 3,000 children, showed error scores to be inversely related to age and sex. Learning disabled children and a group of below average readers made significantly more errors, indicating that visual reversals are dysfunctional for reading skills.
