Which field of psychology believed that psychology should be an objective science and not reference mental processes?

Behaviorism

Explanation:

Behaviorism, also known as behaviorism, is an area of psychology that has behavior as its object of study. Behaviorism emerged as opposed to functionalism and structuralism, and is one of the three major streams of psychology, along with form psychology (Gestalt) and analytical psychology (psychoanalysis).

Behaviorism contemplates behavior as a functional and reactionary form of living organisms. This psychological current does not accept any relation to the transcendental, introspection and philosophical aspects, but aims to study objective behaviors that can be observed. This is because behaviorism is the field of psychology that believes that psychology should be an objective science and not make reference to mental processes.

the answer is false, i know this answer is late but its for anyone else that needs it.

the psychologist would claim that the research results were significant.
