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.
Behavioural genetics, also referred to as behaviour genetics, is a field of scientific research that uses genetic methods to investigate the nature and origins of individual differences in behaviour.
Traditionally, the human behavioural genetics were a psychology and phenotype based studies including intelligence, personality and grasping ability. During the years, the study developed beyond the classical traits of human behaviour and included more genetically associated traits like genetic disorders (such as fragile X syndrome , Alzheimer ...
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). [4]
However, it is widely accepted that variance in gene sequence affect behavior, and genes are a significant risk factor for personality disorders. [20] With the growing interest in using molecular genetics in tracing the biological basis of personality, [8] there may be more gene-trait links found in the future.
Genetics can have an impact on one's development of personality. Genes are passed on from one generation to the next and contain characteristics of one's being. Personality can be influenced through many genes acting together. These genes can be huge indicators especially in the temperament and even certain psychiatric disorders in people.
The theory behind cognitive genomics is based on elements of genetics, evolutionary biology, molecular biology, cognitive psychology, behavioral psychology, and neurophysiology. Intelligence is the most extensively studied behavioral trait. [1] In humans, approximately 70% of all genes are expressed in the brain. [2]
A proposed mechanism for the difference in these patterns is the variation of microsatellite DNA length that is upstream of the V1a receptor gene—short microsatellite DNA in the 5' flanking region of the gene has a different effect on prairie vole behavior than longer microsatellite DNA. Whether this is a mechanism that is replicable in the ...
