Which early psychological theory includes the belief that we cannot examine the structures of the mind and their functions individually because ""the whole is greater than the sum of its parts"" and because we must look at the ""big picture"" to analyze behaviors and cognition.

Holism.

Explanation:

The term 'holism' was coined by a South African Statesman named Jan C. Smuts. He coined the term by joining two words 'holo' meaning 'whole' and 'ism'. Holism is also an approach to study the human mind.

According to the psychological theory of Holism, the notion is that elements can not be understood in parts but as a whole, because they have their own way of behaving. So, to understand the parts it is important to understand the whole system.
