(b) Ziehen replaces 'apperception' by `asso ciation.' A certain lumber of increments of intensity are added together till finally the verbal judgment, 'greater: results by a process of association. If the original stimulus be large,' it takes a relatively greater increment to call forth the judgment.

lel.Meinong contends that too much emphasis has been put upon 'just noticeable differences;' such differences may not be equally great or equally noticeable. We must distinguish between difference and 'differentness' or diversity. In an arithmetical series one obtains an expression of the former category, in a geometrical series an expression of the latter. The mind takes note of diversity, not of difference; e.g. it notes not that an intensity difference of 2 less 1 equals one of 101 less 100, but rather that the relation of 2 to 1 is like that of 200 to 100.
