Neuropsychological and psychosocial correlates of adult arithmetic deficiency.
The purpose of this study was to examine adult correlates of rule-derived arithmetic deficiency. The authors collected neuropsychological, handedness, gender, and psychosocial data of adults with stringently defined arithmetic deficiency (AD; N = 45), reading deficiency (N = 45), and dual deficiency (N = 45). The authors did not match groups on IQ score and did not restrict analyses to right-handed men. The results indicated that AD in adults is associated with nonverbal reasoning and constructional problems. Otherwise, there was no association between AD and dysphoric complaints as defined by Minnesota Multiphasic Personality Inventory elevations. The authors also found overall intelligence was lower in adults with AD, and gender distribution differed markedly from the reading and dual deficient groups. Potential gender bias in remediation referral patterns was identified.
