Maoa and Aggression: A Gene–Environment Interaction in Two Populations
Political scientists tend to focus on environmental triggers as the primary precipitating cause for political violence. However, little has been done to explain why certain individuals faced with certain pressures resort to violence, while others confronting the same situation seek out diplomatic and peaceful resolutions to conflict. Here, using two independent samples, we explore the interaction between genetic disposition and violent early life…
It’s the end of ideology as we know it
Scholars have long focused on socio-psychological attachment, elite discourse, and rational action to explain the nature and structure of ideologies. Recently genetic and neurobiological influences have also emerged as predictors of ideological preferences. So far however, there has been little synthesis of these findings into the larger discourse on the structures and manifestations of ideology. The few studies which do include genetic sources o…
Interaction Between the Serotonin Transporter Gene (5-HTTLPR), Stressful Life Events, and Risk of Depression: A Meta-analysis
CONTEXT: Substantial resources are being devoted to identify candidate genes for complex mental and behavioral disorders through inclusion of environmental exposures following the report of an interaction between the serotonin transporter linked polymorphic region (5-HTTLPR) and stressful life events on an increased risk of major depression. OBJECTIVE: To conduct a meta-analysis of the interaction between the serotonin transporter gene and stress…
A Twin Study of Sexual Behavior in Men
Depression scale scores in 8–17‐year‐olds: Effects of age and gender
Background: The excess of unipolar depression in females emerges in adolescence. However, studies of age effects on depression scale scores have produced divergent estimates of changes from childhood to adolescence. Method: We explored possible reasons for this discrepancy in two large, longitudinal samples of twins and singletons aged 8–17. Results: There were no differences between twins and singletons in their scores on the Short Mood and Feel…
Testing hypotheses on specific environmental causal effects on behavior
There have been strong critiques of the notion that environmental influences can have an important effect on psychological functioning. The substance of these criticisms is considered in order to infer the methodological challenges that have to be met. Concepts of cause and of the testing of causal effects are discussed with a particular focus on the need to consider sample selection and the value (and limitations) of longitudinal data. The desig…
Genetic and environmental contributions to the variance of the body mass index in a Norwegian sample of first‐ and second‐degree relatives
Height and weight were measured in a health screening of the population in Nord-Trøndelag, Norway. Correlations for the body mass index were computed for 23,936 pairs of spouses, 43,586 pairs of parents and offspring, 19,151 pairs of siblings, 1,251 pairs of grandparents and grandchildren, 1,146 cognate avuncular pairs, 801 noncognate avuncular pairs, 168 pairs of same-sexed twins, and smaller groups of other types of relatives. Correlations were…
Environmental and genetical causes of variation in ethological aspects of behavior in two‐year‐old boys
The interactive behavior of two‐year‐old male twins (17 MZ, 29 DZ pairs) with their parents was observed in the home and laboratory. Behavior counts, ratings, and experimental measures were subjected to a biometrical genetic analysis. A model which included only within‐and between‐families environmental effects fitted most variables best, except for Instrumental Independence (a rating) and Speech Rate (a count variable) which showed a significant…
The zygosity of twins: Further evidence on the agreement between diagnosis by blood groups and written questionnaires
The agreement between zygosity diagnosis in twins by reference to the twins' own answers to written questions and diagnosis based on an objective assessment of zygosity by blood-typing is studied for 178 pairs of same sex twins. Seventy-two female and 106 male twin pairs answered two questions concerning their similarity in appearance and frequency of confusion in childhood, and were blood-grouped using up to 23 different antisera. Of those pairs…
The nature of extraversion: A genetical analysis
A biometrical-genetical analysis of twin data to elucidate the determinants of variation in extraversion and its components, sociability and impulsiveness, revealed that both genetical and environmental factors contributed to variation in extraversion, to the variation and covariation of its component scales, and to the interaction between subjects and scales. A large environmental correlation between the scales suggested that environmental facto…
