Behavior genetics has demonstrated that genetic variance is an important component of variation for all behavioral outcomes, but variation among families is not. These results have led some critics of behavior genetics to conclude that heritability is so ubiquitous as to have few consequences for scientific understanding of development, while some behavior genetic partisans have concluded that family environment is not an important cause of developmental outcomes. Both views are incorrect…

The Fourth Law of Behavior Genetics

A Fourth Law of Behavior Genetics is proposed: “A typical human behavioral trait is associated with very many genetic variants, each of which accounts for a very small percentage of the behavioral variability.”

Chapter 9 Behavior genetics of prosocial behavior

To fully understand this body of work, the quantitative genetic methodology is introduced and the types of prosocial phenotypes that have been examined are reviewed, to explain what the accumulating evidence reveals about the origins of prossocial behavior.

Nature, Nurture, and Individual Change

Determining the degree to which persistent human behaviors and traits are the result of genetics or environment is important for a host of theoretical reasons in psychology. This article asks whether

A phenotypic null hypothesis for the genetics of personality.

A Phenotypic null hypothesis is offered, which states that genetic variance is not an independent mechanism of individual differences in personality but rather a reflection of processes that are best conceptualized at the phenotypic level.

Beyond Heritability

The heritability of human behavioral traits is now well established, due in large measure to classical twin studies, and environmental studies of discordant twin pairs and twin studies of genetic and environmental transactions are discussed.

The Effect of Providing Peer Information on Retirement Savings Decisions

Behavior genetics is the study of the relationship between genetic variation and psychological traits. Turkheimer (2000) proposed “Three Laws of Behavior Genetics” based on empirical regularities

Interpreting Behavior Genetic Models: Seven Developmental Processes to Understand

Two primary questions are considered: How might the simultaneous operation of several mechanisms of gene–environment (GE)-interplay affect behavioral genetic model estimates and at what level of GE-interplay does the ‘gloomy prospect’ of unsystematic and non-replicable genetic associations with a phenotype become an unavoidable certainty?

Analysis and interpretation of twin studies including measures of the shared environment.

Claims about estimating environmental influences on behavior with genetic effects controlled are overstated and structural equation modeling and DeFries-Fulker analysis are sound tools for the analysis of many types of twin data.

This article examines-and finds serious flaws with-both the methodologies of behavior genetics and the underlying assumptions concerning the genotype-phenotype relationship.

Simulating the dynamics of genes and environment in development

A series of simulations are presented to suggest that some of the difficulty of identifying environmental effects in biometric models is methodological, which leads to systems in which environment produces substantial variability that can be detected in the context of a particular genotype, but vanishes when genotype is allowed to vary.

Heritability and biological explanation.

All human behavior that varies among individuals is partially heritable and correlated with measurable aspects of brains, but the very ubiquity of these findings makes them a poor basis for reformulating scientists' conceptions of human behavior.

Annotation: the analysis of variance and the analysis of causes.

This issue of the American Journal of Human Genetics contains two articles by Newton Morton and his colleagues 1,2 that provide a detailed analytic critique of various estimates of heritability and

Nonshared environment: a theoretical, methodological, and quantitative review.

The authors review the conceptual foundations of nonshared environment, with emphasis on distinctions between components of environmental variance and causal properties of environmental events and between the effective and objective aspects of the environment.

Why are children in the same family so different from one another?

It is suggested that environmental differences between children in the same family (called "nonshared environment") represent the major source of environmental variance for personality, psychopathology, and cognitive abilities and is responsible for most environmental variation relevant to psychological development.

Developmental theories for the 1990s: development and individual differences.

It is argued that an evolutionary perspective can unite the study of both species-typical development and individual variation and research on determininants of development from many perspectives can be understood within an evolutionary framework in which organism and environment combine to produce development.

Experiential Canalization of Behavioral Development: Theory.

In exploring the possible experiential canalization of development, it was found that the mallard duck embryo's contact call plays a canalizing role in species-speci fic perceptual development, and normally occurring experience can canalize behavioral development.

Some Conceptual Deficiencies in ‘Developmental’ Behavior Genetics

In recent years, some behavior geneticists have applied the statistical procedures of the population-genetic approach within evolutionary biology to the study of psychological development. A widely re

Abstract Theories in “soft” areas of psychology lack the cumulative character of scientific knowledge. They tend neither to be refuted nor corroborated, but instead merely fade away as people lose
