A number of studies compared identical twins reared separately from birth‚ or close thereafter‚ and found numerous similarities. 1. When examining these two you are looking for concordance rates. Critics of separated twin studies note that such similarities can be found between strangers. Researchers point out that differences in fraternal twins is more

project was completed in 2003. One way to show that genetic inheritance can influence behaviour is by studying twins. There are two types of twins‚ monozygotic and dizygotic. The monozygotic twins are genetically identical as they are the formation of a split fertilised egg and the dizygotic twins are roughly 50 percent identical because they are formed by having two fertilised eggs. The dizygotic twins don’t have to be of the same sex which is useful to psychologists because they can use the different

Heredity Versus Environment Identify the main characteristics of the nature/nurture debate and explain how this can be applied to gender difference A major debate within psychology is whether it is nature or nurture which influences people; the way people act and behave‚ cognitive development‚ and what we look for in a partner are just some aspects of the debate. Nature supporters‚ or Naturists‚ believe that our behaviour is down to genetics and is inherited from our parents. They believe that

John Broadus Watson‚ the father of American behaviorism‚ greatly reinforced the source of nurture by studying learned and adaptive behavior patterns in our environmental surroundings (Rathus p.13). During this same time of revolutionary ideas in psychology‚ American psychologist‚ Arnold Gesell supported the opposite views of Watson. Gesell theorized that

Identical twins share all of their genes while fraternal twins share‚ on average‚ half of their segregating genes. As a result‚ greater twin concordances – the probability that a twin is an entrepreneur given that its co-twin is also an entrepreneur – for entrepreneurship between pairs of identical than between pairs of fraternal twins can only be

(1990) performed the ever popular Minnesota Twin study to see whether intelligence was truly heritable. After sampling 100 sets of both monozygotic and dizygotic twins and putting them through psychological and physiological testing‚ the researchers concluded that a large portion of intelligence (70%) can be tied back to genetics‚ which exemplifies the last
