Building Jung’s model is like building a clock. You begin at 12 o’clock with perception, that is, becoming aware of something. Then along the vertical perceiving line you draw from 12 o’clock downwards you arrive at 6 o’clock and begin thinking about what you are taking in, Jung called this judgement. Then along the vertical line at 3 o’clock you begin processing this experience by firstly reflecting on your experience then at 9 o’clock you act on your reflection. Jung referred to these two dimensions as introversion (reflecting) and extraversion (acting).
