Psychology Genetic
Interest is growing in the application of evolutionary and genetic behavioral ecological theory to problems of human lifetimes age specific fertility and mortality, population growth, and emerging population-environment interactions. An understanding of human evolution, particularly the effects of environmental constraints on age-specific fertility and mortality offers insights not only into our past, but into modern problems that are both large scale and urgent. Past theories have helped little to illuminate such issues as the transition to small family size.Evolutionary theory has attained the status of new paradigms for personality. Three challenges for the next generation of research are to integrate these disparate approaches to personality (particularly the trait and social-cognitive paradigms), to remedy the imbalance in the person-situation-behavior triad by conceptualizing the basic properties of situations and behaviors, and to add to personality psychology's thin inventory of basic facts concerning the relations between personality and behavior. In the past few years, three new basic paradigms for the study of personality have joined the four classics just considered. Two of these--the social-cognitive and biological
The fourth and most significant behavioral genetics presents its biggest opportunity. Conversely, when environmental factors are etiologically more significant than the genetic ones, the frequency for an illness among relatives of the adoptive parents may be higher than among the relatives of the biological parents. However, this conclusion is based on a complex analytic technique, and its data consist almost entirely of self-report questionnaires--when behavioral measures are used the shared family environment appears more important. Adoption studies rely on the premise that when a disorder has a genetic basis, the frequency of a disorder among members of the biological family will be higher than the frequency of that disorder among members of the adoptive relatives. The overall paradigm for these investigations is based on the premise that if an illness has a genetic component, then the frequency of that illness will be higher among the biological relatives of identified pro bands when compared to the prevalence in the general population. The modern field of evolutionary psychology can be said to have begun with the sociobiology. Family aggregation studies have also been used to study the genetic factors involved in psychiatric disturbances. The third--evolutionary psychology--deserves to be considered a new paradigm in its own right. The situation is not much different today. The entire field is based upon calculations of the similarities and differences among closer and more distant relatives in scores on self-report personality inventories. Evolutionary ideas became an important part of biology beginning. The evolutionary approach to personality, by contrast, focuses on the possibility that behavioral patterns common to all people--human nature itself--has a biological foundation that can be illuminated by considering the evolutionary history of the human species.
