Path analysis of aptitude, personality, and achievement scores in Brazilian twins
Behav Genet.
1976 Oct.
Abstract
Achievement at school and performance on the Dominoes test, the Differential Aptitude Tests (DAT), and Griéger's Characterological Questionnaire of 45 monozygotic and 46 same-sex dizygotic pairs of twins were analyzed using a new linear model for familial corrrelation. For 14 of the 20 sets of data, the genotype's contribution to the total variance is estimated to be higher than 50%. The effect of common environment seems to be important only for achievement in Arts.
