The effectiveness of a Semantic Feature Treatment (SFT) at increasing
word retrieval accuracy of untreated words was examined in relation to the
influence of the number of shared features with treated words. Generalization of
these improvements to discourse was also examined. METHODS: Three adults with
chronic aphasia completed 12 SFT sessions. Generalization to untreated words with
many shared features (SFs) and with no shared features (NSFs), as well as
generalization to discourse tasks, was analyzed. RESULTS: All participants
improved in word retrieval accuracy for treated words. Accuracy of retrieving
untreated words improved for two participants. Retrieval accuracy for untreated
words with SF improved more than for words with NSF. Generalization of
improvements to discourse tasks occurred for two participants. CONCLUSIONS: SFT
improves word retrieval accuracy for some people with aphasia during
confrontation naming and discourse tasks. Generalization may be slightly higher
for untreated words with SFs than untreated words with NSFs. Future research is
needed to further investigate the effect shared features have on generalization
of improvements, and to determine candidacy for SFT.
