Needs are imposed by nature and wants are sold by society. Nature and Nurture plays a very vital role in development and behavioural changes. The aim of this research is to find out the influence of nature and nurture on behavioural changes in the light of lifespan development perspectives. For this purpose randomly selected eighty children from two different environments, family and hostel of Bilaspur district, Bilaspur, Chhattisgarh were divided into four groups - 1. Family, 2. Hostel, 3. Family and Hostel and 4. Control group. Pre and post scores on behavioural changes factors, rapidity of change in behaviour, behavioural change realization and response time were measured using flash cards, quizlets and reaction timers respectively. The difference between pre and post test scores of the four groups were statistically analysed and the results proved that there was significant improvement in rapidity of change in behaviour and behavioural change realisation (P > 0.05) and there was insignificant difference in behavioural change factor response time of the children. Thus, It was concluded that nurture undoubtedly plays a much more important role in early human development bringing about behavioural changes as in some way or the other nurture also speeds up an individual's capacity to study and learn new things.
