  • Title: Neuropsychological concomitants of calculation skills in college students referred for learning difficulties.
    Author: Cirino PT, Morris MK, Morris RD.
    Journal: Dev Neuropsychol; 2002; 21(2):201-18. PubMed ID: 12139200.
    Abstract:
    The contributions of 3 conceptual domains from a theoretical model of math skill (Geary, 1993) were examined in a large sample of college students referred for assessment of possible learning disorders. Measures were chosen from a comprehensive neuropsychological battery, and from the Wechsler Adult Intelligence Scale-Revised, to represent each of the 3 domains (semantic retrieval, executive-procedural, and visuospatial). The proposed model was examined using structural equation modeling (LISREL), and factors representing the 3 latent domains were derived. The domains of semantic retrieval and executive-procedural skills together accounted for approximately 17% of the variance in calculation skills. The domain of visuospatial skills failed to account for significant incremental variance.
