Abstract Details

2008, Master of Arts, Case Western Reserve University, Experimental Psychology.
The purpose of this study was to: 1) examine the cognitive and temperament correlates of math achievement through structural equation modeling and 2) apply genetic analyses to test for shared variance across intelligence, specific cognitive abilities, temperament, and math achievement. Participants were a subsample of 324 (87 monozygotic, 75 dizygotic) twins from the Western Reserve Twin Project. Structural equation modeling indicated that there is a hierarchical organization to math skill and cognitive abilities mediate the relationship between general intelligence and math achievement. Multivariate genetic analyses indicated that 1) general intelligence accounts for over half the covariance between specific cognitive abilities and math achievement and 2) temperament factors show a genetic pattern distinct from general intelligence or cognitive ability.
