“…Further, his percentage of neologisms dropped to 2%, indicating improved word-level retrieval within discourse. The lower word count and higher content density in P1's typed responses is consistent with previous comparisons of spoken and written discourse (Behrens, Wengelin, Broberg, & Hartelius, 2009). P2 did not improve on typed discourse.…”

Background: A number of computerised treatments have been developed for aphasia, but few have remediated typing, an important functional task, and/or been implemented over the Internet via teletherapy, which can increase access to therapeutic services. The current study created a computerised version of Verb Network Strengthening Treatment (VNeST) and administered it via telerehabilitation over the Internet. VNeST is a semantic treatment which seeks to improve lexical retrieval of words through the conceptual connection between verbs and thematic roles. Previous iterations of VNeST have shown improvement in both spoken and written lexical retrieval for people with moderate and moderate-to-severe aphasia. Aims: This study investigates changes to lexical retrieval with four hierarchical outcome measures. The research questions were: Does treatment using Computerised VNeST (VNeST-C) result in pre-to post-treatment increases in: (1) spoken and typed lexical retrieval of trained (e.g., The farmer is weighing the apples.) and untrained words (e.g., The carpenter is measuring the lumber.) in a picture description task, (2) untreated singleword naming accuracy of nouns and verbs in spoken and typed modalities, (3) spoken and typed lexical retrieval as measured by informative words, efficiency of production and complete utterances within discourse, and (4) standardised measures of cognitive and language abilities? Methods & Procedures: Two people with aphasia were treated three times per week for 8 weeks using the VNeST-C program. A single-subject experimental design was used to evaluate changes in trained and untrained stimuli and tasks. Additional pre-treatment and post-treatment testing was also conducted. Outcomes & Results: Results indicate improvements on lexical retrieval during sentence production of trained and untrained stimuli. Additional improvement was observed for single-word naming of untrained nouns and verbs in spoken and typed modalities and standardised measures of aphasia and writing-by-hand. Limited generalisation to discourse was also observed, including a general increase in word output and decrease in typed neologisms.

BackgroundFew studies have investigated how people with aphasia (PWA) experience literacy skills. Taking the insider's perspective is a way to increase understanding of the individual experiences of literacy among PWA, which may have clinical implications.AimsTo describe how literacy, i.e., reading and writing, is experienced in everyday life by PWA and to gain insight into the part played by literacy skills in their lives.Methods & ProceduresA qualitative descriptive research approach was taken. In‐depth interviews were conducted with 12 PWA (six women and six men) who had all lived with aphasia for at least 6 months post‐stroke. The interviews were analysed using qualitative content analysis.Outcomes & ResultsOne overarching theme emerged from the data: literacy as an ongoing recovery process. Based on this overarching theme, two subthemes were identified: changes in conditions for literacy (experiences of reading and writing initially post‐onset compared with experiences at the time of the interview); and facing expectations about literacy (participants’ own and other people's expectations of them in terms of literacy).Conclusions & ImplicationsThe findings are important at a general level in that they indicate that PWA are able to articulate their individual experiences and thoughts about literacy, i.e., reading and writing. Specifically, PWA in this study experience literacy as playing an essential part in their lives and the findings imply that personal experiences are important in the design of reading and writing interventions in speech and language therapy.

“…Regardless of the total output or the total number of specific words they produce, most individuals with aphasia use a restricted set of words (e.g., Armstrong, 2001; Behrns, Wengelin, Broberg, & Hartelius, 2009; Crutch & Warrington, 2003; Fergadiotis & Wright, 2011; MacWhinney, Fromm, Holland, Forbes, & Wright, 2010). For example, Fergadiotis and Wright (2011) elicited connected speech from 25 people with mild to moderate anomic or conduction aphasia and from 27 neurologically healthy people, and found that people with aphasia produced a lower ratio of word types to word tokens (adjusted for narrative length, i.e., using the D measure).…”

Do age-related word retrieval difficulties appear (or disappear) in connected speech?

We conducted a comprehensive literature review of studies of word retrieval in connected speech in healthy aging, and reviewed relevant aphasia research that could shed light on the aging literature. Four main hypotheses guided the review: (1) Significant retrieval difficulties would lead to reduced output in connected speech. (2) Significant retrieval difficulties would lead to a more limited lexical variety in connected speech. (3) Significant retrieval difficulties would lead to an increase in word substitution errors and in pronoun use, as well as to greater dysfluency and hesitation in connected speech. (4) Retrieval difficulties on tests of single-word production would be associated with measures of word retrieval in connected speech. Studies on aging did not confirm these four hypotheses, unlike studies on aphasia that generally did. The review suggests that future research should investigate how context facilitates word production in old age.
