In 1976 Loehlin and Nicholls examined the scores on self-report personality questionnaires of 800 pairs of twins. Nearly all traits showed moderate genetic influence, with monozygotic (identical) twins being much more similar than dizygotic (fraternal or non-identical) twins. A more extensive study (Loehlin, 1992) of 24,000 twin pairs in many different countries confirmed that monozygotic twins are much more similar than dizygotic twins on the Big Five personality dimensions.
Riemann, Angleitner and Strelau (1997) found the same results when twins were rated by their friends on the same factors. Studies of genetically unrelated family members (parents and their adopted children) show no similarity in personality traits such as extraversion and neuroticism (Loehlin, 1992). Thus both adoption studies and twin studies are consistent with a genetic influence on personality.
Until researchers began to look at genetic components in personality, psychologists had generally assumed that familial similarities are caused by similar environments. However, it is a mistake to view familial environments as shared between family members. Children growing up in the same family can experience very different lives, and even common family experiences such as death or divorce are experienced differently by different siblings (Dunn & Plomin, 1990).
Therefore, it is perhaps not surprising that recent studies have tended to downplay the role of the ‘shared environment’, because often it is not fully shared between family members.
Recent research also suggests that parenting behaviour may be influenced by genetic components of the child’s personality. Plomin, DeFries and Fulker (1988) found that adoptive parents were more responsive to their adopted children whose natural mother had been high on activity and impulsivity. It is therefore possible that children who are genetically more active and impulsive cause their parents to be more responsive to their needs than other children.
