sD
useful to compare groups on exemplars that were clearly
idiosyncratic. For the recall of things owned, 97
exemplars, representing 1018 of the 1200 total items, were
listed by more than one subject. For the recall of. things
not owned, 88 exemplars, representing 932 of the total 1200
items, were listed by more than one subject. For example,
of the experimenter-present group, 13% listed "bed" as an
owned thing, placing it on average in the 7th position of
the 10 item listings. Of the experimenter—-absent group, 8%
listed "bed", placing it on average in the 7th position.
The greatest difterence between the two groups occurred with
the exemplar "boat". Of the experimenter-present group, 42%
listed it as a thing not owned, placing it on average in
position 3.8, whereas 62% of the experimenter-absent group
listed "boat", placing it on average in position 3.1. Such
a large difference might be explained as a sex difference,
since males predominated in the experimenter-absent group,
and females predominated in the experimenter-present group.
In any case, using the Wilcoxon Matched-Pairs Signed-Ranks
Test, the two groups did not difter on the relative
frequencies of the 97 exemplars of owned things that were
examined (p = .91), nor did they differ on the mean recall
positions of those exemplars (p = .97). For the things not
owned, the two groups were more dissimilar, but still not
significantly different on the relative frequencies of the
88 exemplars examined (p =.71), nor on the mean recall
