Projection

 Projection is the misattribution of a person’s undesired thoughts, feelings or impulses into another person who does not have those. It is used especially when the thoughts are considered unacceptable for the person to express. For example, a spouse may be angry at their significant other for not listening, when in fact it is the spouse who does not listen.

Dissociation

 

Dissociation is when a person loses track of time and/or person, and instead finds another representation of their self in order to continue in the moment. A person who dissociate often loses track of time or themselves and their usual thought processes. People who have a history of any kind of childhood abuse often suffer from dissociation. In extreme cases, dissociation can lead a person to believe that he has multiple selves. In this case, a person who dissociates can disconnect from the real world for a time, and live in a different world that is not cluttered with thoughts or feelings that are unbearable.

Compartmentalization

 

Compartmentalization is a lesser form of dissociation, wherein parts of oneself are separated from awareness of other parts and behaving as if one had separate sets of values. For instance, an honest person who cheats on their income tax return but is otherwise trustworthy in his financial dealings. In this way, he keeps the two value systems distinct and sees no hypocrisy in doing so.

Compensation

Compensation is a process of psychological counterbalancing perceived weakness by emphasizing in other arenas. by emphasizing and focusing on one's strengths, a person is recognizing they cannot be strong at all things and in all areas in their lives. for instance, when a person says " I may not know how to cook, but i can sure do the dishes!", they're trying to compensate for their lack of cooking skills by emphasizing their cleaning skills instead.
