@entity1 @entity72444 @entity814 @entity1314 @entity815 @entity669
The purpose of this study was to find out how genetic and biochemical limitations influence psycho-social performance and to partially test the validity of justification theory. The ability to convert @entity815 to @entity669 was compared with intellectual and personality characteristics in @entity814 family members. Each of the tested @entity1 was given an oral dose of @entity815 , the Shipley-Hartford Intelligence Test, and the Minnesota Multiphasic Personality Inventory (MMPI). Only those @entity1 with reading ability at the sixth grade level or higher were tested. Eighty-six @entity1 were tested: fifteen @entity72444 , forty-three siblings, and twenty-eight parents. A comparison was made among parents, @entity72444 , and the siblings. Siblings with the higher 2/3's of P2/T ratios were contrasted with those with the lowest 1/3 of ratios on measures of intelligence and psychopathology. Statistical analyses of the data reflected a trend in support of the justification theory. @entity72444 had significantly lower intelligence than their sibs and parents. The @entity72444 ' mean IQ was 95 (homozygotes born of heterozygotes), followed by the upper 2/3's sibling mean IQ of 105 (heterozygotes born of nonheterozygote mothers). The lower 1/3 siblings' mean IQ was 107 (nonheterozygotes born from heterozygote mothers), and finally, the parents' mean IQ was 109 (heterozygotes, among them 50% were born from nonheterozygote mothers). The latter three mean IQs are not significantly different from each other. The personality tests revealed a trend toward more abnormality in @entity72444 than in their heterozygote siblings. The lowest rate of abnormality occurred in the nonheterozygote sibling group; that rate was significantly lower than in all other groups. The parents had the highest absolute rate of @entity1314 , but statistically so compared to the low-ratio siblings.
