Good post on emotional defences.In addition to these 3 more emotional mechanisms are sublimation,reaction formation,repression.
By Repression we can make the decision to bury the memory in the subconscious, thereby preventing painful, disturbing or dangerous thoughts.
With Reaction fromation, we behave in the opposite way to which we think or feel.
Sublimation is a positive form of defence.if u have a fight with your partner it rurns to play music.
Anyhow nice to meet u
Thank you
