“…Furthermore, most approaches tap into more than one level of processing and may therefore have effects at several processing levels (e.g. Hillis, 1989;Howard, Hickin, Redmond, Clark, & Best, 2006; but for a purely semantic approach see Le Dorze, Boulay, Gaudreau, & Brassard,1994).…”

“…Previous studies using repetition cues have proposed that attempting to name a picture with concurrent exposure to the word form strengthens the links between semantics and phonology (e.g. Howard, Hickin, Redmond, Clark & Best, 2006;Miozzo et al, 1996;. In a connectionist account such as that of Dell et al (1997) this would entail increased activation of the target word's semantic nodes and phonological nodes, leading to selection of the target, as opposed to a related word.…”

Effects of syntactic cueing therapy on picture naming and connected speech in acquired aphasia

Language therapy for word-finding difficulties in aphasia usually involves picture naming of single words with the support of cues. Most studies have addressed nouns in isolation, even though in connected speech nouns are more frequently produced with determiners. We hypothesized that improved word finding in connected speech would be most likely if intervention treated nouns in usual syntactic contexts. Six speakers with aphasia underwent language therapy using a software program developed for the purpose*, which provided lexical and syntactic (determiner) cues. Exposure to determiners with nouns would potentially lead to improved picture naming of both treated and untreated nouns, and increased production of determiner plus noun combinations in connected speech. After intervention picture naming of treated words improved for five of the six speakers, but naming of untreated words was unchanged. The number of determiner plus noun combinations in connected speech increased for four speakers. These findings attest to the close relationship between frequently co-occurring content and function words, and indicate that intervention for word-finding deficits can profitably proceed beyond single word naming, to retrieval in appropriate syntactic contexts. We also examined the relationship between effects of therapy, and amount and intensity of therapy. We found no relationship between immediate effects and amount or intensity of therapy. However, those participants whose naming maintained at follow-up completed the therapy regime in fewer sessions, of relatively longer duration. We explore the relationship between therapy regime and outcomes, and propose future considerations for research.

“…However, the notion is not implausible when placed in the context of connectivity of neuronal assemblies. In their therapy study, Howard et al (2006) go on to show how spoken word-picture matching tasks facilitated subsequent picture naming, and Fridriksson, Baker, Whiteside, Eoute, Moser, Vesselinov, et al (2009) revealed similar findings in treating word production difficulties in non-fluent aphasia. These results suggest that grounding therapy in neurobiological realities might result in improved outcomes.…”

Rethinking aphasia therapy: A neuroscience perspective

This article explores how consideration of acquired speech and language disorders from the perspective of neuroscience permits new insights into the content and design of therapy for people with aphasia. Key proposals are that aspects of current therapies often neglect the sensory-motor components of speech and language processing, and the interconnectivity of sensory-perceptual and motor systems. Furthermore, current therapy regimes are often administered at too low an intensity to stimulate neural reorganization. Neuroscientific perspectives on learning are explored and in particular the issues of associationist learning, learned misuse, mirror neurone systems, and procedural and errorless learning. The value of use of computer programs in administering high intensity therapy is outlined and it is proposed that aphasia therapies can be enhanced if clinicians adopt an explicit neuroscientific rationale for intervention.
