Cognitive functions personality test

Cognitive functions, also referred to as psychological functions, as described by Carl Jung in his book Psychological Types, are particular mental processes within a person's psyche that are present regardless of common circumstance. This is a concept that serves as one of the foundations for his theory on personality type. In his book, he noted four main psychological functions: thinking, feeling, sensation, and intuition. He introduced them with having either an internally focused (introverted) or externally focused (extraverted) tendency which he called "attitudes".
