Although geometric analogies are popular items
for measuring intelligence, the information processes
that are involved in their solution have not
been studied in a test theory context. In the current
study, processing is examined by testing alternative
models of information structure on geometric
analogies. In contrast to the treatment of models in
other studies that have appeared in the cognitive
literature, the models are tested jointly as mathematical
models of processing and as latent trait
models of individual differences. The joint modeling
was achieved by applying the one-parameter linear
logistic latent trait model to predict response
accuracy from information structure. The results
supported the model that distinguished between
spatial distortion and spatial displacement transformations,
which have opposite effects on item difficulty.
Further, no significant sex difference in overall
accuracy or processing were observed. Implications
of the results for processing mechanisms and
test design are discussed.
