Personality traits are patterns of thoughts, feelings and behaviors that reflect the tendency to respond in certain ways under certain circumstances. [1] Personality is influenced by genetic and environmental factors and associated with mental health. [2] Beside the environment factor, genetic variants can be detected for personality traits.
However, it is widely accepted that variance in gene sequence affect behavior, and genes are a significant risk factor for personality disorders. With the growing interest in using molecular genetics in tracing the biological basis of personality, there may be more gene-trait links found in the future.
Genetic basis of personality. Ever since the Human Genome Project allowed for a much more in depth comprehension of genetics, there has been an ongoing controversy involving heritability, personality traits, and environmental vs. genetic influence on personality. The human genome is known to play a role in the development of personality.
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. Behavioral genetics refers to the results of adoption studies and twin studies.
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. While the name "behavioural genetics" connotes a focus on genetic influences, the field broadly investigates the extent to which genetic and ...
Human behaviour genetics is an interdisciplinary subfield of behaviour genetics that studies the role of genetic and environmental influences on human behaviour. Classically, human behavioural geneticists have studied the inheritance of behavioural traits. The field was originally focused on determining the importance of genetic influences on ...
Personality neuroscience is a field built upon the study of personality, which has been a central theme in psychology and evolving through various theoretical perspectives as well as methodological approaches over many years. Specifically, personality neuroscience aims to understand what neurobiological mechanisms underlie and contribute to ...
Personality is not stable over the course of a lifetime, but it changes much more quickly during childhood, so personality constructs in children are referred to as temperament. Temperament is regarded as the precursor to personality. Another interesting finding has been the link found between acting extraverted and positive affect. Extraverted ...
