The criteria associated with candidacy were attentuated 
in the calculation of the difference scores, shown in Table 
8, to the point that Territoriality gained a prominence. In 
the rank ordering, Possession again was the dominant 
criterion, with Assertion a close second. Territoriality 
and Familiarity had relatively similar importance to 
ownership. Territoriality as a more dominant criterion 
would also be consistent with the findings of the third 
pilot study that the most common strategy for recalling 
owned things was to list items in various territorial 
spaces. (See Appendix D.) At the low end of the ranking 
again were Crafting and Gift, along with the dominant 
criteria of the listings of things not owned, i.e. Desire, 
Aesthetics, and Knowledge. It is important to note that the 
difference scores had a possible range of -3 to +3, and that 
none of the median values of the difference scores went into 
the negative numbers. This means that all of the 12 
criteria had some degree of applicability to ownership and 
were, therefore, reasonable criteria to have included in a 
study of ownership. 
The explicit judgements of the criteria, displayed in 
Table 9, resulted in quite a different rank ordering of the 
criteria. Most notably, Purchase was judged by almost all 
subjects to be a "very strong" argument for owning 
something. And the two second place criteria, Crafting and
