Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).

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.
For example, laboratory house mice have been bred for open-field behaviour, [16] thermoregulatory nesting, [17] and voluntary wheel-running behaviour. [18] A range of methods in these designs are covered on those pages. Behavioural geneticists using model organisms employ a range of molecular techniques to alter
Excellent examples of this model are the Virginia 20,000 and the QIMR twin studies. Generally, if the observed behaviour and cognitive traits have a genetic component, then genetically similar relatives resemble to each other as comparative to individuals who share lesser component of genome.
In 1983, psychology professors Sandra Scarr and Kathleen McCartney proposed that genes affect the environments individuals choose to interact with, and that phenotypes influence individuals’ exchanges with people, places, and situations. [2]
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]
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 ...
Many examples of genetic factors of social behavior have been derived from a bottom-up method of altering a gene and observing the change it produces in an organism. Sociogenomics is an integrated field that accounts for the complete cellular genetic complement of an organism from a top-down approach, accounting for all biotic influences that ...
