Based upon the Jungian personality theory, the test suggests that personality is composed of a number of different cognitive functions. These functions can be focused primarily outward (extraverted) or inward (introverted). Each of these functions relate to how people perceive the world and make decisions.
The dominant function is the most prominent aspect of personality, while the auxiliary function plays a supporting role. The tertiary function has a weaker influence, but can become more apparent when a person is under stress. The inferior function is primarily unconscious and is often a point of weakness.
Developing this aspect can help people form a more balanced personality.
Juggling is a gift that keeps on giving if it grabs your interest.
