title: Relationship of left-right reversals to academic achievement.
abstract: The study was designed to investigate the relationship of reversal of letters and numbers to academic achievement to decide if the tendency to reversal might be used to predict achievement. Two groups of 45 predominantly white third-grade students whose chronological ages were 9.0 yr. or above were administered the California Achievement Tests and the Jordan Left-Right Reversal Test. A statistical comparison was made using scaled scores on the California Achievement Tests and raw errors on the Jordan Left-Right Reversal Test. Reversal was significantly correlated with academic achievement. Children who exhibit reversals at 9 yr. of age or older may be expected to perform less well academically than children who do not reverse letters.
