I believe the answer is: Biopsychology
Byopsychology studies the correlation between our physical condition to the behaviour that we displays in our interraction. The chemistry that released by our brain under certain situation would affect the emotion that we felt at that time, which would most likely influence how we behave in response to that emotion.
If you are trying to match a term with that definition I think you answer would be bureaucracy (<span>a system of government in which most of the important decisions are taken by state officials rather than by elected representatives)</span>
