In the memory when a combination of two or more SPs DSPs reoccurs, a connection in the memory is formed. For instance, if a smell_x occur with specific sound_y, and this combination reoccur several time while still in memory, then the memory might assume that the combination is eminent. This will be called induction, because from some limited set of co-occurrence, the mind assume that this co-occurrence will always reoccur. Of course the induction might not stand the next occurrence of either one of the SPsDSPs. We will deal with this later.
