Final answer:
Projection is the psychological defense mechanism where individuals unconsciously shift their own feelings onto someone else rather than acknowledging them within themselves.
Step-by-step explanation:
The psychological defense mechanism that involves the unconscious transfer of one's own feelings, impulses, or thoughts onto another person is known as projection. This is an ego defense mechanism that occurs when a person refuses to acknowledge their own uncomfortable feelings and instead sees those feelings as being possessed by someone else. Projection allows an individual to avoid confronting their own internal conflicts by shifting the blame or negative feelings onto another person. Other related mechanisms include repression, displacement, and sublimation.
