Which plays the major role in children’s personalitydevelopment, nature or nurture?
雅思大作文范文：
Over the past few decades there has been anongoing nature-versus-nurture debate about thecauses of children’s personality. To the best of myknowledge, there are many influences on thedevelopment of a child’s personality, but the maincauses are his genetic makeup, environment, andbehavioral genetics.
There is evidence that both genetics andenvironment affect children’s personality. Studieshave shown that the tendency to acquire some personality characteristics – including activitylevels, anxiety, aggression, and independence – can be inherited. Although one’s geneticmakeup does not determine one’s behavior, it provides a child strong tendency to behave in aparticular way.
Personality is also influenced by environment. Thus, a child with particular personalitycharacteristics is more likely to show them if the home environment reinforces them. Forexample, harshly punishing a child who has a genetically based tendency for aggressioncontributes further to the child’s aggression.
Major advances have been made through behavioral genetics, the field concerned with therelative influence of genetic and environmental factors on individual behavior. For example, if westudy the personalities of identical twins who have been separated since birth, we may findthat the twins have the same genetic makeup but differ in the environments in which they arereared. Similarities and differences can help reveal the relative importance of genetic andenvironmental influences.
To sum up, the shaping of a child’s personality is attributed mainly to the role of specific socialexperiences and environmental events, his genetic makeup as well as the behavioral genetics.
