“…Furthermore, Mason-Baughman and Wallace (2013b) found significant differences in high-importance distinctive (HID) feature knowledge versus low-importance distinctive (LID) feature knowledge demonstrating that level of importance may also affect distinctive feature knowledge. However, Mason-Baughman and Wallace (2013a) indicated that distinctive mid- and low-importance features are not differentially impaired in people with aphasia, replicating the findings of Germani and Pierce (1995) and Cox (2009). Taken together, the results suggest that LID feature knowledge is the most impaired in people with aphasia and that mid-importance distinctive (MID) feature knowledge may be indiscernible from LID feature knowledge.…”

“…Feature knowledge was tested by having participants match features to target nouns presented in arrays of three semantically unrelated nouns. In addition, people have aphasia appear to have a decreased appreciation of distinctive features (Mason-Baughman, 2010; Mason-Baughman & Wallace, 2013a, 2013b).…”

“…Research has demonstrated that people with aphasia have significantly more difficulty identifying low-importance features than non-impaired adults (Cox, 2009; Germani & Pierce, 1995). In addition, several studies have demonstrated that people with aphasia have increased difficulty identifying distinctive features as compared with common features across semantic categories (Mason-Baughman, 2010; Mason-Baughman & Wallace, 2013a, 2013b; Vecchi, 1994).…”

“…The interaction of these two feature considerations has been examined previously in people with chronic aphasia (Mason-Baughman, 2010; Mason-Baughman & Wallace, 2013a, 2013b). Generally, two tasks have been used in this research to examine semantic feature knowledge: the Sorting Features Task (SFT) and the Related Semantic Foils Task.…”

“…Given these promising results, researchers sought to examine feature knowledge relative to both distinctiveness and importance (Mason-Baughman & Wallace, 2013a, 2013b). Findings from these studies indicated that distinctive feature knowledge as compared with common feature knowledge was more impaired in people with aphasia.…”

Previous studies suggest that people with aphasia have incomplete lexical-semantic representations with decreased low-importance distinctive (LID) feature knowledge. In addition, decreased LID feature knowledge correlates with ability to discriminate among semantically related words. The current study seeks to replicate and extend previous research that identified patterns of feature knowledge in people with aphasia. Ten adults with aphasia sorted high-, mid-, and low-importance common and distinctive features. Participants formed two groups based on accurate discrimination of semantically related foils. ANOVA results showed significant main effects for feature importance, feature distinctiveness, and group. Participants with difficulty discriminating among related foils had greater difficulty with the identification of LID features as compared with the other group. Previous findings were replicated demonstrating impaired LID feature knowledge in people with aphasia. Careful examination of semantic feature knowledge is needed to enhance the design of future semantic feature treatments.

Purpose: We investigated from a theoretically motivated perspective what information differentiated sufficient from insufficient descriptions of objects provided by persons with aphasia. Method: Twenty-one adults with aphasia consequent to single left-hemisphere stroke verbally described 9 living and 9 nonliving objects. Responses were scored for accuracy (i.e., sufficiency) and tallied for type and quantity of semantic feature information provided. Main effects and interactions were identified using repeated measures analyses of variance, with significant findings followed up with planned comparisons. Results: Differences between correct and incorrect descriptions were identified with respect to both feature type and feature distinctiveness for living and nonliving items, in particular highlighting the importance of distinctive features in descriptions of both domains. Conclusions: These findings add to the relatively small body of literature investigating semantic feature processing in adults with aphasia. This is a critical gap to close when considered in light of the preponderance of semantically based treatments for word-retrieval impairment in strokeaphasia. Our findings provide preliminary support for the notion that semantically guided treatments for word-retrieval impairment in stroke-aphasia may be geared toward increasing specificity of semantic circumlocution to increase semantic self-cueing and to improve communication of information to conversation partners.

The role of commonality, distinctiveness and importance of semantic features in persons with aphasia

Abstract: These results suggest that distinctive feature knowledge contributes in a significant way to the integrity of semantic representations in people with aphasia which can influence their performance of language tasks.
