Abstract

This study examined the ability of individuals with unilateral left hemisphere damage (LHD) and right hemisphere damage (RHD) to complete multiple modality analogy tasks. Four groups, for a total of 46 subjects--12 LHD patients, 8 RHD patients, 20 child control subjects, and 6 adult control subjects--performed word, figure, and picture analogies. The combined non brain damaged control groups performed significantly better than the combined brain damaged experimental groups on the combined analogy tasks. No significant difference was found between the LHD and RHD groups on the combined analogy tasks. The modalities of analogical reasoning tasks did not differentially affect the performances of the LHD patients. However, RHD patients performed significantly better on the Word Set analogies than on the Figure Set analogies. In general, analogical reasoning abilities of LHD and RHD patients were poorer than the control subjects, but did not differ from each other.
