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.

Comparative Effectiveness of Semantic Feature Analysis (SFA) and Phonological Components Analysis (PCA) for Anomia Treatment in Persian Speaking Patients With Aphasia.
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.
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.
The primary objective of the present study, which has been conducted in the Persian language, was to provide more evidence regarding the selection of an appropri- ate treatment approach by a patient’s underlying defi- cits within a cognitive processing model.
Participants with pure impairments at the semantic level or phonological level participated in the study to answer the following clinical question: For individuals with aphasia, what is the relationship be- tween underlying functional deficit and responding to a particular treatment?
Participant 1 Visual inspection of graphical data (Figure 1) revealed that both treatment approaches resulted in improvement of naming following therapy.
Although both SFA and PCA tasks showed to im- prove naming ability in participants, effects of those items which were trained using treatment approach targeting underlying deficit were great.
