Psychology 9-1 GCSE - 

3.3.1 - Understand the nature and nurture debate, including:

a) The term 'nature' - 

Nature simply means the properties or characteristics of us that are determined since birth, rather than created through experience. 

b) The term 'nurture' - 

Nurture means the properties or characteristics we develop or learn through experience and how we are nurtured.

c) the use of content, theories, and research drawn from psychological problems to explain the nature and nurture debate - 

Our nature may provide natural limits as to how much we can process and learn, but we can, through nurture fulfil this capacity. So nature is the overall determining factor. Francis Galton investigated this through various studies and assessments. When he did a study using twins, even if the twins had very different nurture they both turned out extremely similar.
