Answer:
The answer is psychodynamics.
Explanation:
Psychodynamics is an approach to psychology which is mostly concerned with unconscious motivation for behaviour. According to this theory, several parts of the human mind, such as personality, interact directly with emotions.
One of its founders was Sigmund Freud, who believed the brain was in a constant "flow of energy", and compared the forces of the mind to those of thermodynamics (hence the name).
