Evolutionary Perspectives on Personality and Individual Differences

  title={Evolutionary Perspectives on Personality and Individual Differences},
  author={Yael Sela and Nicole Barbaro},
Individual differences are essential to the process of evolution by natural selection. Natural selection is the only known process capable of creating and maintaining adaptations. The properties of inheritance, variation, and differential reproduction are required for evolution of adaptations (see Sela and Shackelford, 2015, for a review). Physiological and psychological traits must be genetically heritable and reliably passed from parent to offspring in order for natural selection to act upon… 

Beyond nature vs. nurture in expertise research – comment on Baker & Wattie

This commentary argues that there are always limits on human performance, even among individuals who have engaged in long periods of intensive training, and that variation across people in phenotypes reflecting these limits will have a genetic component.

The Motivational Architecture of Emotions

It is argued that the current view of emotions as coordination mechanisms should be extended—and partially revised—to include motivational systems as an additional control layer, responsible for the activation and deactivation of specific emotions in the pursuit of domain-specific goals.

Exploring Gender Differences in Moral Intelligence and its Effects on the Learning Outcomes of Second Year College Students

The current study was undertaken with the primary objectives of exploring differences in moral intelligence due to gender and determining moral intelligences effect on the learning performance of

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.

The author argues that each of the Big Five dimensions of human personality can be seen as the result of a trade-off between different fitness costs and benefits, and that genetic diversity will be retained in the population.

The Evolution of Personality and Individual Differences

Capturing a scientific change in thinking about personality and individual differences that has been building over the past 15 years, this volume stands at an important moment in the development of

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.

Adaptive Individual Differences

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

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.

Plasticity as a developing trait: exploring the implications

Some implications of the idea that the early environment modulates long-term plasticity are explored, with an emphasis on plasticity in behavioral traits and how plasticity may become a target of evolutionary conflict between parents and offspring are discussed.
