Using LISREL to analyze genetic and environmental covariance structure.
Martin and Eaves (1977) developed a method for the analysis of genotypic and environmental covariance structure based on the work of J6reskog (1973). Their method is a general approach to the analysis of covariance structure which allows simultaneous testing of hypotheses about the sources and structure of covariation. The method provides maximumlikelihood estimates of genetical and environment...
متن کاملGenetic and Environmental Influences
review the literature on handedness, dichotic listening and anatomical asymmetry in schizophrenia and concluded that there was strong evidence for decreased cerebral lateralisation. As they point out, the implication is that finding the locus of the gene for cerebral dominance could unravel the genetic predisposition to schizophrenia. Procopio (2001) raises a number of points relevant to the fi...
متن کاملRunning head: GENETIC AND ENVIRONMENTAL INFLUENCES Genetic and Environmental Influences on Prosocial Behavior
The obvious importance to human social functioning of prosocial behavior (behavior intended to benefit others) has led to extensive research on the sources of individual differences in prosociality, empathy, helping, cooperation, and altruism. At the species level, this markedly human trait has been explained in genetic terms. At the individual level, however, only about a dozen studies have di...
متن کاملGenetic and environmental influences on risky sexual behaviour and its relationship with personality.
Risky sexual behaviour is a major health issue in society, and it is therefore important to understand factors that may predispose individuals to such behaviour. Research suggests a link between risky sexual behaviour and personality, but the basis of this link remains unknown. Hans Eysenck proposed that personality is related to sexual behaviour via biological underpinnings of both. Here we te...
متن کاملGenetic and environmental influences on infant sleep.
BACKGROUND Sleep duration is attracting increasing attention in relation to chronic disease risk, but few large-scale studies have investigated the determinants of sleep characteristics in early life. In this study we used data from a large, population-based twin study to examine genetic and environmental influences on sleep duration and sleep difficulties in infancy. METHODS Participants wer...
