“…The results of this study partially concur with previous findings of SFA investigations [20][21][22][23], showing that treatment resulted in positive changes for trained items. However, we found no generalization to naming of untrained actions in this investigation, whereas improvements in untrained object-naming have been reported for all previous SFA participants who demonstrated improvements with trained items.…”

“…Additionally, generalization may be facilitated by application of the compensatory strategy of systematically retrieving features, which may serve a self-cueing function. SFA has been demonstrated to result in improved retrieval of trained nouns and has been shown to promote retrieval of untrained nouns [20][21][22][23]. SFA has also been associated with improvements in content production during discourse.…”

Abstract-This investigation examined the effects of a semantic feature training procedure on retrieval of action names in a participant with anomic aphasia. Treatment was applied sequentially across two sets of action names in the context of a multiple baseline design across behaviors. Treatment effects were evaluated in terms of naming of trained and untrained actions. Discourse production effects were also examined with respect to verbal productivity, informativeness, and production of nouns and verbs. Increased accuracy of naming was observed for both sets of trained action names, with increases being maintained at 6 weeks posttreatment. However, accuracy of responding did not reach preestablished criterion levels. Repeated exposure to stimulus items without training resulted in unstable and temporary increases in naming accuracy. No changes were observed in accuracy of naming of untrained actions that were measured only at pre-and posttreatment intervals. Increases in verbal productivity and informativeness in discourse production were associated with the treatment.

“…The results indicated that confrontation naming on trained and untrained stimulus items was significantly improved. The results of this study have shown that SFA treatment is effective in improvement of naming deficits [10,11]. A recent systematic review has also indicated that SFA was an effective treatment for improving confrontational naming in the majority of participants.…”

Objectives: Anomia is one of the most common and persistent symptoms of aphasia. Although treatments of anomia usually focus on semantic and/or phonological levels, which both have been demonstrated to be effective, the relationship between the underlying functional deficit in naming and response to a particular treatment approach remains unclear. The aim of this study was to determine the relationship between the effects of specific treatments (Semantic feature Analysis and Phonological Components Analysis) and their underlying functional deficit patterns within the framework of a cognitive processing model. Methods:In an ABCB reversal control task design, four participants with aphasia were selected according to the criteria based on using a cognitive model of lexical processing. Each patient received two types of treatment. In SFA, features semantically associated to the target words were elicited from the patient, whereas in PCA treatment, the phonological components of the target words were the focus of treatment. Naming accuracy scores obtained in pretreatment baseline phase were compared to post-treatment accuracy scores. Here, both itemspecific effects and generalization of untrained items were analyzed.Results: Both SFA and PCA treatments have the potential to improve naming ability in participants; however, the treatment approach that corresponds exactly to the underlying deficit causing failure in word retrieval is more effective.Discussion: While PCA is more effective for participants with phonological impairments, SFA is more effective for participants with semantic impairments. Therefore, a direct relationship between underlying functional deficit and response to specific treatment was established for all participants.

“…However, many of these studies have found little generalization to untrained items. Notably, studies focused on strengthening the semantic attributes of target items have been more successful at facilitating generalization to untrained items (Boyle, 2004;Boyle & Coehlo, 1995;Coehlo, McHugh, & Boyle, 2000;Drew & Thompson, 1999;Kiran & Thompson, 2003a;Lowell, Beeson, & Holland, 1995). Whereas some of these studies have focused on generalization to items within a superordinate category (Drew & Thompson, 1999), others have also observed generalization to items across semantic categories (Boyle, 2004;Boyle & Coehlo, 1995;Coehlo et al, 2000;Lowell et al, 1995).…”

Purpose-This paper discusses a novel approach for treatment of lexical retrieval deficits in aphasia in which treatment begins with complex, rather than simple, lexical stimuli. This treatment considers the semantic complexity of items within semantic categories, with a focus on their featural detail.Methods and Results-Previous work on training items within animate categories (Kiran & Thompson, 2003a) and preliminary work aimed at items within inanimate categories are discussed in this paper. Both these studies indicate that training atypical category items that entail features inherent in the category prototype as well as distinctive features that are not characteristic of the category prototype results in generalization to untrained typical examples which entail only features consistent with the category prototype. Conversely, training typical examples does not result in generalization to untrained atypical examples. In this paper, it is argued that atypical items are more complex than typical items within a category and a theoretical framework for this dimension of semantic complexity is discussed. Then, evidence from treatment studies that support this complexity hierarchy is presented. Potential patient-and stimulus-specific factors that may influence the success of this treatment approach are also discussed.Conclusions-The applications of semantic complexity to treatment of additional semantic categories and functional applications of this approach are proposed.
