What Is Modified Semantic-Based Treatments?

Decent Essays

Modified Semantic-Based Treatments Another important question/factor involved with implementation SFA surrounds efficacy and efficiency of such treatments. To this end, variations of the SFA protocol have also proven effective. For example, Hashimoto and Frome (2011) investigated whether the SFA approach could be modified and still produce naming improvements in an individual with non-fluent aphasia and apraxia of speech resulting from a left hemisphere CVA. Rather than using the traditional six semantic features, Hashimoto & Frome (2011) used only three features (group, properties, association) to train three superordinate categories (clothing, animals, musical instruments) in twice-weekly, 1-hour sessions until the criterion was met of ≥ …show more content…

Importantly, Hashimoto & Frome (2011) considered this trend and proposed this effect was more likely to be due to improved access to the semantic system rather than just generalization to the treatment process since two of the three features (group, properties) incorporated cues that were wholly unique to those categories. However, the study lacked a control set of untrained words or categories which would have helped confirm this. Still, another potentially important and related insight is that the categories which showed the largest drop at the maintenance probe also achieved criteria fastest and were therefore treated for the least time, whereas the initial category which was treated for the most sessions, retained the highest level. This suggests that perhaps a minimum set of sessions may be required to overcome a “threshold” to sustain results rather than just achieving a criterion (Hashimoto & Frome, 2011). More recently, Mehta and Isaki (2016) also made several modifications to the traditional model of six semantic features. First, they excluded the semantic feature of association. They eliminated the association feature, theorizing that it could be addressed via category, properties, and a new personal memory feature (i.e., episodic memory). They also eliminated “action,” suggesting that “use” better addresses both inanimate and animate
