Family patterns in four dimensions of lateral preference

摘要: Hand, eye, foot, and ear preference were examined in a sample of 459 biologically related parent-offspring triads 434 sibling pairs. Intercorrelations computed using the side as dependent variables then again absolute, strength displayed irrespective side. The directional analyses did not show strong patterns familial similarities; however, relatives tend to resemble each other degree lateralization manifested. Maternal paternal resemblance offspring vary over four indices laterality, there are some suggestions sex-specific interactions. These results imply that genetic influence may operate affect expressed preference, while be genetically encoded. findings also suggest lateral preferences for limb sense organ due single causal mechanism.
