Adaptive Individual Differences

  title={Adaptive Individual Differences},
  author={Davie M. Buss and Heidi Greiling},
  journal={Journal of Personality},
Individuals differ in innumerable ways, some adaptive, some maladaptive, and some neutral. Personality theories, we argue, can profit from distinguishing among these importantly different types of individual variation. This article outlines a taxonomy of origins of individual differences—environ- mental sources of adaptive differences(e.g., early environmental calibration), heritable sources of adaptive differences (e.g., adaptive self-assessment of heritable qualities), nonadaptive sources of… 
Individual Differences in Attitude Change
The term individual differences refers to how people differ with respect to a wide variety of factors such as personality, motives, and abilities. Conceptualizations of individual differences in
Adaptive Individual Differences Revisited
An eloquent and engaging commentary, Kirkpatrick explores the issue of whether indi- vidual differences in attachment styles and mating strategies represent adaptive individual differences or, conversely, whether departures from secure attachment and long-term mating represent maladaptive deviations produced by evolutionarily novel environmental conditions.
CHAPTER 32 Individual differences
This chapter outlines the key frameworks that the authors have for explaining distributions of individual differences from an adaptive perspective, primarily on heritable individual differences, that is, differences underlain by population polymorphisms of particular genes.

    Perspectives on psychological science : a journal of the Association for Psychological Science
  • 2009
Some promising theoretical directions for tackling the explanatory question of personality and individual differences are highlighted, which include life-history theory, costly signaling theory, environmental variability in fitness optima, frequency-dependent selection, mutation load, and flexibly contingent shifts in strategy according to environmental conditions.
Evolutionary Perspectives on Personality and Individual Differences
Individual differences are essential to the process of evolution by natural selection, and the number of successful offspring determines gene frequency of particular traits in a population to the extent that it contributes to successful gene propagation.
Toward a Basis for the Phenotypic Gambit: Advances in the Evolutionary Genetics of Animal Personality
The term “animal personality” is used throughout this chapter to describe an emergent phenomenon of the total biases in behavioral reactions an individual expresses compared to other individuals within the same population or species.
Evolutionary Genetics of Personality in Nonhuman Primates
Our whole conception and acknowledgement of personality – both scientific and quotidian – is based on the notion of difference. A personality is precisely that which distinguishes one individual from

Pattern and Adaptation in Individual Behavioral Differences
This chapter reviews the reports of variation in social and foraging behavior and considers the existing explanations for this variation, and develops a framework for further study which relates the appearance and controls on individuality to the life history of an organism and the dynamics of its foraging and social environments.
Evolutionary biology and personality psychology. Toward a conception of human nature and individual differences.
It is argued that, although substantial problems remain, evolutionary biology can provide one means for identifying relations between individual differences and species-typical characteristics and some of the difficulties of this endeavor are identified.
On the universality of human nature and the uniqueness of the individual: the role of genetics and adaptation.
An evolutionary approach to psychological variation reconceptualizes traits as either the output of species-typical, adaptively designed development and psychological mechanisms, or as the result of genetic noise creating perturbations in these mechanisms.

Evolution, the Five-Factor Model, and Levels of Personality
ABSTRACT This article interprets the five-factor model as subsuming variation in normative, species-typical systems with adaptive functions in the human environment of evolutionary adaptedness. It is

Abstract Contemporary mate preferences can provide important clues to human reproductive history. Little is known about which characteristics people value in potential mates. Five predictions were
Toward an evolutionary history of female sociosexual variation.
It is argued that genetic variance on this trait for females could have been maintained through frequency-dependent selection and one prediction that follows from this evolutionary history is tested and supported in three studies.
Derogation of Competitors
Verbal signals are sometimes used to manipulate the impressions that people form about oneself and others. For the goal of self-enhancement, one can manipulate impressions either by elevating oneself

In species with internal female fertilization, males risk both lowered paternity probability and investment in rival gametes if their mates have sexual contact with other males. Females of such
