title: An Empirical Demonstration Of The Factor Differentiation Hypothesis.
abstract: The factor differentiation hypothesis suggests that the factor structure of a set of tests tends to differentiate over time, becoming more complex and articulated. Three hundred seventy-one naval recruits were assigned to one of three groups: a control group and two experimental groups who received training on a spatial visualization test. Confirmatory factor analyses demonstrated that the experimental groups had more differentiated factor structures for a battery of spatial tests, confirming the hypothesis that environmental manipulations can induce factor differentiation.
