Abstract
Two distinct approaches, one based on item response
theory and the other based on observed item
responses and standard summary statistics, have been
proposed to identify unusual response patterns of responses
to test items. A link between these two approaches
is provided by showing certain correspondences
between Sato’s S-P curve theory and item
response theory. This link makes possible several extensions
of Sato’s caution index that take advantage of
the results of item response theory. Several such indices
are introduced and their use illustrated by application
to a set of achievement test data. Two of the
newly introduced extended indices were found to be
very effective for purposes of identifying persons who
consistently use an erroneous rule in attempting to
solve signed-number arithmetic problems. The potential
importance of this result is briefly discussed.
