Evolutionary psychologists consider Charles Darwin's theory of natural selection to be important to an understanding of psychology. [1] Natural selection occurs because individual organisms who are genetically better suited to the current environment leave more descendants, and their genes spread through the population, thus explaining why organisms fit their environments so closely.

For example, the subjective perception of isolation is a stronger predictor of pro-inflammatory gene expression than is the objective size of one's social network. This neurocognitive control of the CTRA suggests that altering one's perception of their social situation, for example by utilizing skills honed in cognitive therapy may be able to ...
While evolutionary views tend to regard most individual differences as the result of either random genetic noise (evolutionary byproducts) [2] and/or idiosyncrasies (for example, peer groups, education, neighborhoods, and chance encounters) [3] rather than products of natural selection, EDP asserts that natural selection can favor the emergence ...
Down syndrome is a genetic syndrome marked by intellectual disability and distinct cranio-facial features and occurs in approximately 1 in 800 live births. [17] Experts believe the genetic cause for the syndrome is a lack of genes in the 21st chromosome. [17] However, the gene or genes responsible for the cognitive phenotype have yet to be ...
One example is the evolutionary psychology model of extended social groups selecting for modern human brains, a contradiction being that the synaptic function of modern human brains require high amounts of many specific essential nutrients so that such a transition to higher requirements of the same essential nutrients being shared by all ...
For humans, the Big Five personality traits, also known as the five-factor model (FFM) or the OCEAN model, is the prevailing model for personality traits. When factor analysis (a statistical technique) is applied to personality survey data, some words or questionnaire items used to describe aspects of personality are often applied to the same person.
Ribot, in 1881, for example, held that psychological and genetic memory were based upon a common mechanism, and that the former only differed from the latter in that it interacted with consciousness. [6] Hering and Semon developed general theories of memory, the latter inventing the idea of the engram and concomitant processes of engraphy and ...
Biological determinism, also known as genetic determinism, [1] is the belief that human behaviour is directly controlled by an individual's genes or some component of their physiology, generally at the expense of the role of the environment, whether in embryonic development or in learning. [2]
