MACCOBY of shared environment are variable, of environmental variation of the reported findings of this important study

Relying on the additive assumption, these investigators have partitioned the variance in child adjustment outcomes into the three components: G, Es, and Eus, reporting substantial contributions from genetics. Effects making clear contributions to some outcomes but not others; in general, though, they are considerably smaller than the substantial contributions from unshared environ- environment may have effects on both members of a sibling pair, but that the effects are not such as to make siblings more alike, but indeed might function to make them more different. We know from Elder's work on effects of the Great Depression (Elder 1974) that when a father loses his job, the effects on the child will depend on the
