Nature vs Nurture debate is one of the oldest arguments in the history of psychology. The debate is about to know if our personality and talents come from our parent or environment? The coding of genes in each cell in humans determine the different traits that we have, more physical attributes dominance like ear size, eye colour, , height, hair colour and other traits. However, it is still not known whether the more abstract attributes like, intelligence, sexual orientation, personality, preferences are gene-coded in our DNA. Biological Perspective (Nativists) The nativist adopts a hereditary perspective. They believe the characteristics that make us human are the outcome of evolution and the coding of genes in each cell in us humans…show more content…
This view suggests attachment behaviours are naturally selected, and passed on as a result of genetic inheritance (heredity mechanisms). Behaviour = attachment, cause = inmate (biological factors) Behavioural psychologists explain attachment in terms of classical conditioning, where food (UCS) is associated with the mother (NS), and through many repeated pairings, the mother becomes a (CS) who elicits a CR in the child. Therefore, the child forms an attachment based on the pleasure experienced as a result of being fed. Behaviour = attachment, cause classical conditioning learning from the mother/environment. Interactionist perspective between nature and nurture The genetic disorder PKU is caused by the inheritance of two recessive genes. People with PKU are unable to break down the amino acid phenylalanine which builds up in the blood and brain causing mental retardation. However, if a child with PKU is placed on a low protein diet for the first 12 years, they avoid this potentially serious lifelong disorder. The integrationist perspective views: as both nature and nurture work together to shape human behaviour. The disorder PKU nature) is not expressed because of an altered environment (low diet – nurture). I can conclude by saying that Nurture + nature = who we are today, since both of them play a very significant part
