Final answer:
Regression, Rationalization, and Projection are ego defense mechanisms used to cope with anxiety and stress.

Regression is an ego defense mechanism where an individual reverts to behaviors of an earlier developmental stage when faced with anxiety or stress. For example, a stressed adult behaving in a child-like manner.
Rationalization involves distorting facts to justify or excuse behaviors to alleviate anxiety. An example is a student blaming lack of interest for poor academic performance.
Projection is when someone attributes their own unacceptable thoughts or feelings to others. For instance, a person feeling insecure accusing others of being insecure.
