Cognitive Function Test

Based on the Work of Myers, Briggs, and Jung

At more advanced levels, Jung's theory of personality deals with the concept of cognitive functions. This free personality test will allow you to obtain your scores on the eight Jungian functions as developed by Jung, Myers, Briggs, Moltzer, Schmid-Guisan, Wolff, von Franz, and van der Hoop. Though function tests have never been shown to have the same validity as traditional type tests, they are nevertheless able to provide a fuller, freer picture of the underlying mechanics of type.

Jung's Psychological Types as well the psychological insights into personality type tests as presented in the work of Isabel Briggs Myers, co-creator of the MBTI® test, as set forth in her work Gifts Differing. Furthermore, the works of van der Hoop, Conscious Orientation and Character and the Unconscious, were also influential in the making of this test.

This test follows established theory. Our test follows the written theory of Jung, Myers, von Franz, and van der Hoop on the topic of personality type, rather than some slapdash approximation of Jung's theory.
