Everyone else is driving recklessly so I will too.
Regression is when you revert back to less mature ways of dealing with things. In this example, the child broke the china and he's lying and saying that he didn't. A mature way of dealing with this situation would be to admit that it was you who broke the plate, and accept the consequences.
Reaction formation is when you act opposite of your beliefs. In this example, the teen is listening to music and saying he hates it in order to fit in.
*punches hole in wall*
*boy is listening to pop music*
Projection is when you disguise your own threatening impulses attributing them to others. In this example, the driver of the red car is driving recklessly, so the driver of the blue car feels that he needs to drive recklessly because the red car is driving recklessly.
Rationalization is when you make excuses for behavior or feelings. In this example, this teen is smoking to fit in and make himself have a "cool" impression.
Displacement is when you redirect an impulse onto a powerless person or object. In this example, this person is punching the wall to release the anger from his parents grounding him over a bad test grade.
Sublimation is when wee turn our emotion into constructive activity rather than destructive activity. In this example, this person is taking a walk to release the stress from his day.
