Genes and Environment in Personality Development

Intriguing information about twins, adoptions and other family relationships is offered in this volume, which explores how genes and environment act jointly to create individual differences in temperament and personality. Loehlin examines the relative contributions of genes and environment to major dimensions of personality and to personality change over time, and discusses how genotype-environment findings for personality compare with neighbouring trait domains such as ability. The book concludes with an analysis of how research results on individual personality variation relate to evolutionary views about human nature.
