“…The mapping that needs to be primed in word retrieval disorders is the output connection between semantics and the lexicon (and from there to phonological representations). Treatments that train semantic features of words are presumably stimulating this pathway, as are self-generated semantic cues, and these approaches have met with some success (Boyle & Coelho, 1995;Marshall, Freed, & Karow, 2001). Massed priming of the output semantic-lexicalphonological pathway could be accomplished with a task that promotes naming of the target rather than just repetition.…”

Background: Repetition priming is often a component of treatments for word-finding disorders. It can facilitate or interfere with naming success depending on a number of factors.Here we investigate the effectiveness of massed priming coupled with semantic or phonological context as a treatment for naming impairments arising from semantic and phonological deficits. Aims: We aimed to determine whether (1) this procedure, used previously in a short-term facilitation study, would effectively improve word retrieval in a treatment study, and (2) the pattern of facilitation or interference observed in the facilitation study would carry over to the treatment programme. Methods & Procedures:We used a single subject multiple baseline design. There were two participants: LP with a phonological encoding deficit and AS with both semantic and phonological deficits. Treatment involved identifying and repeating the names of words that were related semantically or phonologically, or unrelated. Pre and post measures of naming were used to assess overall effectiveness of the treatment. Acquisition, maintenance, and generalisation were measured with baseline tests at the start of each session. Correct responses and errors on within-training naming probes were used to measure sensitivity to priming in a particular context. Outcomes & Results: LP benefited from this procedure regardless of the training context. AS showed interference in the semantic context during training and only modest short-term gains. These outcomes were predicted by their performance on an earlier facilitation study. Conclusions: Contextual repetition priming has different effects on naming and these differences appear to be related to the context of training (semantic or phonological) and the primary source of an individual's naming impairment (semantic or phonological). This procedure is most effective when semantic processing of words is relatively spared.

“…Emphasis has been on establishing the most beneficial therapy technique by looking at one particular therapy with one individual (in a single-case study) and measuring improvement in performance (Francis et al, 2002) or by comparing two different types of therapy in one or more individuals. These include, for example, comparisons of: semantic versus phonological cueing (Chin Li & Williams, 1989;Wambaugh, 2003;Wambaugh, Linebaugh, Doyle, & Martinez, 2001); personalised versus phonological cueing (Marshall, Freed, & Karow, 2001); constraint-induced aphasia therapy versus conventional aphasia therapy (Pulvermuller et al, 2001); decreasing versus increasing cues (Abel, Schultz, Radermacher, Willmes, & Huber, 2005;Conroy, Sage, & Lambon Ralph, 2009); errorless versus errorful therapy (Fillingham, Hodgson, Sage, & Lambon Ralph, 2003;Fillingham, Sage, & Lambon Ralph, 2006).…”

“…This is probably because repetition can be accomplished without ever stimulating the top-down connection between semantics and the lexicon. Other tasks that strengthen that activation, such as semantic feature training 21,22 or direct priming of the semantic-lexical connection, should meet with more success.…”

In this article, we review an account of movement errors that is based on a model of serial order and an interactive spreading activation model of word production. This account makes two claims. First, anticipations and perseverations arise from malfunctions of a mechanism that maintains serial order in speech production and that has three components: (1) a means to turn off past utterances, (2) a means to activate the present utterance (3) a means to prime the future utterance. Second, the probabilities of such movement errors are further determined by the same variables that influence the production of ordinary word and sound substitutions, such a frequency and feature overlap. We review relevant studies of movement errors produced by aphasic and nonaphasic individuals and make suggestions for further investigation of these phenomena.
