“…Despite that various measures were adopted, lexical retrieval of nouns and in particular verbs were consistently evaluated for documenting treatment generalization (see also Carragher et al, 2013). While we agree that positive changes in conversation should bean important goal of any language rehabilitation, further insights into the nature of changes in language performance of individuals with aphasia can only be gained if psycholinguistic properties, e.g.…”

“…The ecological validity of single word production has, however, been questioned by some when it comes to understanding daily verbal communication of normal speakers as well as speakers with aphasia in rehabilitation (e.g. Carragher, Conroy, Sage, & Wilkinson, 2012; Carragher, Sage, & Conroy, 2013; Crepaldi, Ingignoli, Verga, Contardi, Semenza, & Luzzatti, 2011). As such, there have been attempts to examine grammatical class effects in the contexts of single word production as well as connected speech.…”

Effects of context and word class on lexical retrieval in Chinese speakers with anomic aphasia

Background Differences in processing nouns and verbs have been investigated intensely in psycholinguistics and neuropsychology in past decades. However, the majority of studies examining retrieval of these word classes have involved tasks of single word stimuli or responses. While the results have provided rich information for addressing issues about grammatical class distinctions, it is unclear whether they have adequate ecological validity for understanding lexical retrieval in connected speech which characterizes daily verbal communication. Previous investigations comparing retrieval of nouns and verbs in single word production and connected speech have reported either discrepant performance between the two contexts with presence of word class dissociation in picture naming but absence in connected speech, or null effects of word class. In addition, word finding difficulties have been found to be less severe in connected speech than picture naming. However, these studies have failed to match target stimuli of the two word classes and between tasks on psycholinguistic variables known to affect performance in response latency and/or accuracy. Aims The present study compared lexical retrieval of nouns and verbs in picture naming and connected speech from picture description, procedural description, and story-telling among 19 Chinese speakers with anomic aphasia and their age, gender, and education matched healthy controls, to understand the influence of grammatical class on word production across speech contexts when target items were balanced for confounding variables between word classes and tasks. Methods & Procedures Elicitation of responses followed the protocol of the AphasiaBank consortium (http://talkbank.org/AphasiaBank/). Target words for confrontation naming were based on well-established naming tests, while those for narrative were drawn from a large database of normal speakers. Selected nouns and verbs in the two contexts were matched for age-of-acquisition (AoA) and familiarity. Influence of imageability was removed through statistical control. Outcomes & Results When AoA and familiarity were balanced, nouns were retrieved better than verbs, and performance was higher in picture naming than connected speech. When imageability was further controlled for, only the effect of task remained significant. Conclusions The absence of word class effects when confounding variables are controlled for is similar to many previous reports; however, the pattern of better word retrieval in naming is rare but compatible with the account that processing demands are higher in narrative than naming. The overall findings have strongly suggested the importance of including connected speech tasks in any language assessment and evaluation of language rehabilitation of individuals with aphasia.

“…The participants had previously completed a verb retrieval treatment, after which only two participants demonstrated improvements to sentence production (Carragher et al . ). Taken together, the results of the current study indicate that, in order to affect change in sentence production, it was necessary to target production of verbs within syntactic structures (for similar arguments, see Mitchum et al .…”

“…The participants had previously taken part in a treatment study targeting verb retrieval (Carragher et al . ) and were included in the current study based on evidence of structurally impoverished output during picture description, with a paucity of verbs in relation to nouns, reduced length and complexity of utterances and omission of grammatical morphology (see appendix ). All participants were at least 6 months post‐onset, reducing the likelihood of further spontaneous recovery.…”

Improvement in language production in constrained assessment tasks may not impact on everyday conversations. Implications for further research are discussed, e.g. the need for bridging interventions between constrained and unconstrained contexts of language production. Clinical implications include the potential to streamline therapy planning and delivery by making use of rich, hybrid therapies to treat individuals with similar symptom profiles but with a range of underlying deficits.

What is Functional Communication? A Theoretical Framework for Real-World Communication Applied to Aphasia Rehabilitation

Aphasia is an impairment of language caused by acquired brain damage such as stroke or traumatic brain injury, that affects a person’s ability to communicate effectively. The aim of rehabilitation in aphasia is to improve everyday communication, improving an individual’s ability to function in their day-to-day life. For that reason, a thorough understanding of naturalistic communication and its underlying mechanisms is imperative. The field of aphasiology currently lacks an agreed, comprehensive, theoretically founded definition of communication. Instead, multiple disparate interpretations of functional communication are used. We argue that this makes it nearly impossible to validly and reliably assess a person’s communicative performance, to target this behaviour through therapy, and to measure improvements post-therapy. In this article we propose a structured, theoretical approach to defining the concept of functional communication. We argue for a view of communication as “situated language use”, borrowed from empirical psycholinguistic studies with non-brain damaged adults. This framework defines language use as: (1) interactive, (2) multimodal, and (3) contextual. Existing research on each component of the framework from non-brain damaged adults and people with aphasia is reviewed. The consequences of adopting this approach to assessment and therapy for aphasia rehabilitation are discussed. The aim of this article is to encourage a more systematic, comprehensive approach to the study and treatment of situated language use in aphasia.
