| Research Abstract |
Behavior Genetics models assume that additive genetic, non-additive genetic, shared environmental, and non-shared environmental factors are the causes of individual differences in phenotypes. However, because of a mathematical limitation, the effects of only the three of these four factors can be estimated. To overcome this problem, the four factor model was identified using structural equation modeling which can analyze higher-order moments.
