I would say that in my life I have made several attitude changes.
My most dramatic attitude change was made when I went to army boot camp and my civilian attitude was changed into a military attitude. The primary purpose of boot camp, in my judgment, was to make this very dramatic attitude change. This required eight weeks of intensive 24/7 effort by a cadre of military officers and enlisted men.
My next big attitude change came with marriage and parenthood.
Wiki informs me that Jung’s definition of attitude is “readiness of the psyche to act or react in a certain way”. He thought that attitude often displayed itself in a dual manner: consciousness/unconsciousness, extraversion/introversion, thinking/feeling, rational/irrational, and individual/social.
What you are referring to is conditioning, which doesn't take anything from the psyche, nor does it add anything to it. The psyche still remains the psyche.
