Defense mechanisms: These are unconscious strategies that individuals use to protect themselves from anxiety or discomfort. Examples include repression (pushing unpleasant thoughts out of awareness) and projection (attributing one's own unacceptable feelings onto others).
Oedipus complex: The Oedipus complex is one concept within Freud's theory that suggests during their childhood, children develop subconscious sexual desires for their opposite-sex parent while competing with their same-sex parent.
