What is the name of the theory that Branden says holds that the thoughts, actions, decisions, etc., of human beings are only a function of passive reaction to external or internal stimulus?

The name of the theory is "PSYCHOLOGICAL FREEDOM". Branden say this theory holds instead of psychological determinism.

Explanation: Psychological freedom is the view that we are free from our wills and actions. This theory explains our actions and behaviour as been influenced by external or internal stimulus from our environment. We often react to what we see, hear, perceive or feel.

While psychological determinism is the aspect of Psychology that see our actions according to our self interest, which is always our strongest and best reason of action.

But according to Branden our actions are not always according to our decision or thoughts, but it is always influenced by our external environment. He see our freedom as, your action not being justified by your thoughts and decision, but as a result of a response to external stimulus, unlike determinism that justify your actions as a result of self will and decision.

Branden believe in Psychological freedom.
