IS THERE SEMANTIC SPECIFICITY IN OVERLAPPING-FIGURES AGNOSIA

A CASE of apperceptive visual agnosia, revealing difficulties only in the performance on a standard overlapping-figures test, has been studi ed. Unusually, the patient demonstrated difficulties only with two sem antic categories of the overlapped figures (clothes and school accesso ries); preserving, however, the knowledge of the same figures when pre sented isolated. We propose that the underlying deficit is only of a p seudo-semantic nature and is actually due to certain similarities of t he two overlapping combinations, creating difficulties still on the ap perception level only.
