    Helping to break new ground in the examination of the genetic basis of behaviour is the use of twin studies, which utilize the medium of concordance rates. Concordance rates provide behavioural geneticists with important data that is used to discern the degree to which genetic vs. environmental influences affect behaviour. They ''rely on some reasonably simple mathematical calculations to determine (1) whether a trait is genetically influenced and (2) the degree to which heredity and environment account for individual differences in that trait.'' (Shaffer, 2009, p.76). Concordance rates among monozygotic twins (identical) as opposed to the concordance rates of dizygotic twins (fraternal) is the preferred methodology used in these studies, due to the fact that monozygotic twins ''share 100pc of their genes, whereas dizygotic twins share 50pc of their genes.'' (Davis et al. 2002, p.673). This is an important distinction to make because not only do dizygotic twins share only 50pc of their genes, the two can also be of different genders, this could affect their development due to the societal expectations and gender roles imposed on them by the outside world.

    In the pre-enlightenment era, religious connotations were usually attached to those suffering from auditory and visual hallucinations. One exhibiting these symptoms would be considered possessed, and the cause of the distress would have been attributed to a malevolent spirit, nowadays, however, one displaying mannerisms such as these would be considered a textbook case of one suffering from schizophrenia. As this fits the criteria found in the 'Diagnostic and Statistical Manual of Mental Disorders' booklet. With modern day reference to this as opposed to religious doctrine, we can categorise the sufferer's condition by looking at the signs and symptoms and conferring with the diagnostic criteria. This change in rationale in favour of a more sceptical approach is thanks to the scientific method. The field of psychology has many of the core tenents of other sciences, in the sense that evidence, research, experiments and falsifiability are the tools of discovery in its attempt to better understand human behaviour.

They ''rely on some reasonably simple mathematical calculations to determine (1) whether a trait is genetically influenced and (2) the degree to which heredity and environment account for individual differences in that trait.'' (Shaffer, 2009, p.76). One of the ways in which researchers hope to come to more definitive results by using these methods is by looking at the study of twins reared apart, as they view this an opportunity where any compounding influences that the environment might be a factor in development have been removed. This would perhaps provide some middle ground in the freewill vs. determinism debate, which are opposing factions in the more general nature-nurture debate, where the ''freewill approach assumes that humans are free to choose their behavior...determinism approach assumes that every physical event is caused, and, since human behavior is a physical event, it follows that it too is caused by preceding factors.'' (Hill, 1998, p.29).

    Case studies involving twins are used in recourse to the nature vs. nurture debate as they provide an invaluable opportunity to test to what extent biological and genetic predisposition (nature), as opposed to the effect the environment one is raised in (nurture), impacts on human traits. This essay will examine these case studies by looking at concordance rates among monozygotic twins (identical) as opposed to the concordance rates of dizygotic twins (fraternal). The reason for this is because monozygotic twins ''share 100percent of their genes, whereas dizygotic twins share 50percent of their genes.'' (Davis, Charney, Coyle and Nemeroff, 2002, p.673). This is an important distinction to make because not only do dizygotic twins share only 50percent of their genes, the two can also be of different genders, this could affect their development due to the societal expectations and gender roles imposed on them by the outside world. Research methods used to separate genetics from environment include the collation of data from previously conducted twin studies such as the Czechoslovakian twins and the children of Garden Island. Other secondary sources used to augment this essay include works by Cara Flanagan (Revise AS Psychology) and Nancy L. Segal (Born together, reared apart). These sources among others will help to bridge the divide between both sides of the argument and enable us to discover to what degree of correlation there is between genetics and identity.

    The nature vs. nurture debate is an ongoing dispute within the study of psychology that aims to better understand to what extent particular aspects of human behaviours that lead to mental illness, substance abuse, criminality and academic success can be understood as a product of either inherited (i.e genetic) or acquired (i.e learned) characteristics. Like many things in western thought, concepts concerning matters of the mind first came to fruition in Ancient Greece, which can be considered the birthplace for this line of questioning. Greek philosophers such as Plato and his student Aristotle hoped to gain insight on the subject through the use of philosophical discourse. The two shared opposing views on the matter, for example ''Plato argued that experience was simply insufficient to account for all the knowledge and abilities humans possess. Because these things cannot be taught, they must instead be present at birth, that is, they are innate. On the other hand, Aristotle...described development as a process of continual integration'' (Goldhaber, 2012, p.14).
