Yung's Model of Typology

In yung's model, there are eight basic types, eight possibilities of functionin. Two of the four functions he termed as rational and the other two as irrational. We generally have one or two auxiliary functions besides the superior function so that thinking often is paired with sensation. And i'm sure you've heard of the myers briggs type indicatorye. It could be a theoretical physicis just to stat in summarizing the structure of his model.
