Which is it nature or nurture that plays the biggest part in behavioural development? The behavioural development debate otherwise known as ‘Nature vs. Nurture’, has been going on for many of years now. Evidence suggests it’s been going on from the thirteenth century. So which plays the biggest part is it nature? Or is it nurture?

Nature
Nature which is known as heredity or innate is the genetic code everyone is born with. We get this genetic code from our parents when conceived. Humans have twenty-three chromosome pairs, which consists of a chain of genes. The moment we are conceived we receive approximately half a set of these from each parent. The chain of genes are known as genotype, which help influence behavioural development. Some examples of nature or heredity could be height, behaviour and IQ to name a few. Nurture

Nurture otherwise referred to as learnt behaviour, is not heredity but is flexible and can be changed. Some examples of nurture could be the environment in which the child is brought up in {i.e. a child that lives in an unhappy home and is then adopted into a happy one is most likely to become happier in its self. Nativists and Empiricists

Nativists strongly believe that the human characteristics as a whole are a product of evolution and that individual differences are due to each person’s unique genetic code. They believe characteristics that are not observable at birth, but later emerge are regarded as the product of maturation. Meaning we all have inner ‘biological clocks’ which switches on types of behaviour in a pre-programmed way. A classic example of this would be the way our physical development changes our body at puberty. However nativists argue maturation governs language acquisition and cognitive development as a whole. Empiricists also known as environmentalists believe that at birth the human mind is a blank slate and that this is gradually “filled” as a result of experience. They...
