Its main focus is on how and why personality traits transcend in biology and links personality and DNA and the process of the brain.
A study on babies by Thomas and Chess (1977) showed their temperaments can be categorised either, slow to warm up, easy or difficult. According to Carter et al., (2008) the interactions a baby has after birth with the environmental factors (interactions with family) mould the child's temperament to form how their personality. From a biological view, genetic and internal physiological factors contribute and influence personality. Its considered the genes which we inherit contribute to why people are successful and can challenge social influences and natural environments. Thus, which one is more significant, the environmental factors, or inherited genes for an individual's personality to develop.
The Minnesota Twin Family Study (MTFS) was established in 1983 to test twins through longitudinal examination. The main goal was to test personality by comparing over 8,000 twins. All twin which were born in Minnesota during were invited for the study. The MTFS looked at same sex twins in pairs …show more content…
In creatures we can complete controlled reproducing examinations to explore the impacts of qualities and environment on different characteristics. Be that as it may this is impossible with people, for both moral (it isn't right to deliver young people exclusively for the motivations behind examining them) and functional reasons (it would take too long). Twin studies include contrasting indistinguishable and non-indistinguishable twins, or indistinguishable twins isolated during childbirth. Indistinguishable twins have the same qualities as each other, since they originate from a solitary prepared egg cell. Non-indistinguishable twins impart just 50% of their qualities to each other. All twins offer (pretty much) the same environment. So by inspecting how often certain characteristics happen in indistinguishable and non-indistinguishable twins we can evaluate how much these qualities are influenced by qualities. In the event that indistinguishable twins are isolated during childbirth (eg for selection) then they will have the same qualities yet diverse situations. This additionally permits the impacts of qualities to be evaluated. Notwithstanding, such twins will have had the same uterus thus will have been liable to comparative, however not indistinguishable, pre-birth situations. These sorts of studies permit the impact of qualities on
