Reducing Anomia

Decent Essays

The aim of Maddy, Capiluto & McComas (2014) was to review the research evaluating the effectiveness of semantic feature analysis on reducing anomia in individuals with aphasia. They used seven databases to search for articles, and seven terms. The author’s search initially identified eighty-eight articles, eighteen of which were relevant. The authors then focused on research that was experimental in nature, examined semantic feature analysis as a treatment method, and included participants that were adults with neurological injury. Next, the parameters included that the articles had to be written in English, and had to have been published in a peer-reviewed journal from 1980 to June 2013. The authors did not include research that looked at semantic feature analysis in combination with another treatment approach. This left the authors with a total of eleven articles to review.
Next, the research was examined for quality. Maddy et al. (2014) selected two speech-language pathologists to review the research independently. Ten of the eleven studies were assessed using the Single Case Experimental Design Scale. One study was not assessed using this method to due the fact it did not use a single subject research design. In addition, each study was evaluated using …show more content…

(2014) then evaluated the efficacy of semantic feature analysis on reducing anomia by calculating the effect sizes of the selected studies using Cohen’s d. The authors also used the calculation of percent of non-overlapping data due to the fact it was not possible to calculate Cohen’s d. for all the studies. The effect size for the majority of participants was small, indicating that semantic feature analysis did not result in significant improvement in word-finding ability for these participants. Some of the participants did show medium or high effect size. When using the measure of percent of non-overlapping data, the use of semantic feature analysis was found to be effective for all
