the recall categories of things owned and things not owned 
are antithetical. "The recall listings for these two 
categories should have little in common. What is shared in 
common could be interpreted as common method variance or as 
a systematic effect of common selection criteria, which 
probably were extraneous to the intensional criteria of 
ownership. For the uncategorized exemplars, 12 of the 26 
most frequent exeuplans were the same for both recall lists, 
although the correlation of recall frequencies was not 
statistically significant. However, there was a significant 
relationship between the two recall listings when the 
frequencies of the 72 recall categories were examined, 
indicating that approximately 20% of the variance in the 
frequencies of the categorized exemplars was shared by the 
owned and not owned listings. Thus, some extraneous, but 
common factors did systematically influence both recall 
tasks. 
The common frequent categories in both recall lists 
were cars, dwellings, TV's, stereos, sports equipment, and 
pets. Apparently, these types of things were generally 
deemed important to list, irrespective of whether they were 
owned or not. The two dominating categories were cars and 
dwellings. It seemed possible that the significant 
relationship between the two antithetical recall Listings 
might have been due to subjects giving prominance to
