Dupuis, Claude – Human Development, 1984
Discusses the conditions for validating customary phylogenetic procedures. Concludes that the requisites of homogeneity and completeness for proved short lineages seem satisfied by the Hennigian but not the Haeckelian procedure. The epistemological antinomy of the two procedures is emphasized for the first time. (Author/RH)

DeFries, J. C.; And Others – Developmental Psychology, 1987
A path model of genetic and family environmental transmission was fitted to published twin correlations and to general cognitive ability data from adoptive and nonadoptive families in which children were tested yearly through the fourth year. Longitudinal genetic correlations from infancy to adulthood were modeled explicitly, as were effects of…

McCain, Katherine W. – Journal of the American Society for Information Science, 1986
To test validity of cocitation studies as representations of intellectual structure, five-six years of aggregate cocitation data for 41 authors in macroeconomics and 49 authors in genetics of fruit flies were compared with independent judgments of interauthor similarity collected from 14 macroeconomists and 15 geneticists via a card-sorting…

Smith, Mike U. – Journal of Research in Science Teaching, 1992
Compares 7 biology faculty members, 9 genetic counselors, and 26 undergraduate students according to both expertise and problem-solving success within the domain of genetics. Findings are consistent with the hypothesis that as expertise is attained, the individual restructures knowledge into a framework based upon the critical dimensions which…

Daniels, Denise; Plomin, Robert – Developmental Psychology, 1985
Used the Sibling Inventory of Differential Experience with 396 adolescent and young adult children to determine the extent to which genetic differences between siblings or sibling differences in family constellation variables were responsible for differential experiences. (HOD)
