Modelling by means of LISREL: Genetic and environmental components of interindividual variance connected to field dependence-independence
(resume)
This article reports a model-fitting analysis of
the covariance structure of the field
dependence-independence data. A model is used
which includes additive and non-additive genetic
parameters, and shared and nonshared environmental
parameters that permit different estimates for
different types of relatives. The opportunity is
taken here to explicate the use of LISREL for such
purposes. The results indicate that, when
assortative mating is included in the model,
nonadditive, as well as additive genetic variance
is important for the field dependence-independence
cognitive style. Broad heritability is estimated
to be 0. 50. Another interesting result is that
the influence of nonshared environment seems to be
crucial when accounting for variance in different
groups of relatives.
