“…These methods might focus on lexical diversity (Rider et al, 2008), production of specific word types like nouns and verbs (Mayer & Murray, 2003), instances of word-finding difficulties (Boyle, 2004a;German, 1991), or analysis of morphological and syntactic production (Rochon et al, 2000;Saffran et al, 1989). The choice of macrolinguistic analysis methods is influenced by the type of discourse elicited.…”

“…Investigations of impairment-based treatments typically focus treatment and outcome measures at the word or sentence level, although recently many studies have assessed whether these treatments of more basic linguistic units result in changed discourse production (Boyle, 2004a;Boyle & Coelho, 1995;Cameron, Wambaugh, Wright, & Nessler, 2006;Coelho, McHugh, & Boyle, 2000;Edmonds, Nadeau, & Kiran, 2008;Faroqi-Shah & Virion, 2009;Rider, Wright, Marshall, & Page, 2008;Schwartz, Saffran, Fink, Myers, & Martin, 1994). In part because the changes in discourse have been inconsistent, investigators have developed treatments that require people with aphasia to work on specific linguistic skills (e.g., word retrieval or syntactic formulation) while they are producing discourses.…”

Background: Impairment-focused aphasia treatment has an ultimate goal of improving language production in connected speech and communication in daily life. Although impairment-based treatment has typically been carried out in words or sentences, investigations have begun to explore the efficacy of treatment during discourse production. Focusing treatment on an impaired linguistic process during discourse production is a complex and challenging endeavour. Aims: This paper aims to review investigations of discourse treatment for word retrieval impairment in aphasia in order to identify and discuss variables that emerge as being important considerations in clinical practice and continued research. Main Contribution: Seven investigations that applied treatments during structured discourse production to improve word retrieval in participants with aphasia were reviewed. Treatment methods used in the investigations included phonologic and orthographic cues, semantic feature analysis, contingency-based cueing hierarchies, and repeated conversational engagement. The discourse contexts used for treatment were structured conversations or structured narrative discourse. All investigations reported positive outcomes for improved word retrieval abilities. Although treated vocabulary items did not improve in all cases, improvements in general processes of word retrieval were reported. Focusing treatment on the linguistic process of word retrieval resulted in changes to discourse macrostructure, at least in terms of the informativeness of the discourse. When attitudes and perceptions of the participants with aphasia or of naïve judges were assessed, the outcomes were generally favourable. One investigation provided evidence that treatment in structured discourse was related to improved word retrieval in real-life conversations.Conclusions: There are several promising discourse treatment approaches for word retrieval impairments in aphasia. Systematic analysis of changes in the macrolinguistic processes of discourse, in real-life conversations, and in the attitudes and perceptions of participants with aphasia and others in future discourse treatment studies would enhance our insights about their efficacy.There has been a great deal of activity in the past two decades in developing treatments at the discourse level for people with aphasia. These investigations reflect a variety of orientations to aphasia treatment. A review of the literature reveals two

“…This inverse relationship is not entirely clear. However, Rider, Wright, Marshall, and Page (2008) found that D values decreased in narratives provided by adults with aphasia following word retrieval treatment. Rider et al suggested that the decrease may indicate that the participants used limited, yet specific, vocabulary in their narrative productions; an ''economy of expression'' in a sense.…”

“…For example, LD has been used to understand the relationship between phonological processing and the development of reading skills (e.g., Smith, 2009); to differentiate typically developing children from children with specific language impairment (e.g., Thordardottir & Namazi, 2007); to screen and identify bilingual children with language deficits (Kapantzoglou, Fergadiotis, & Restrepo, 2010); to evaluate the progress of children after cochlear implantation (Ertmer, Strong, & Sadagopan, 2002); to differentiate individuals with aphasia from neurologically intact adults (e.g., Lind et al, 2009); to capture the differences between individuals with fluent and nonfluent aphasia (Fergadiotis & Wright, 2011); to inform models of language processing in aphasia (e.g., Gordon, 2008); to assess the efficiency of therapeutic approaches (Rider, Wright, Marshall, & Page, 2008); and to use as a possible early marker of dementia (Bucks, Singh, Cuerden, & Wilcock, 2000). …”

Purpose Several novel techniques have been developed recently to assess the breadth of speaker’s vocabulary exhibited in a language sample. The specific aim of this study was to increase our understanding of the validity of the scores generated by different lexical diversity (LD) estimation techniques. Four techniques were explored: D, Maas, Measure of Textual Lexical Diversity (MTLD), and the Moving Average Type Token Ratio (MATTR). Method Four LD indices were estimated for language samples on four discourse tasks (procedures, eventcasts, story retell, and recounts) from 442 neurologically intact adults. The resulting data were analyzed using structural equation modeling. Results The scores on the MATTR and MTLD estimation techniques were stronger indicators of the LD of the language samples. The results for the other two techniques were consistent with the presence of method factors representing construct-irrelevant sources. Conclusions These findings offer a deeper understanding of the relative validity of the four estimation techniques and should assist clinicians and researchers in the selection of LD measures of language samples that minimize construct-irrelevant sources.

Abstract: Results support and extend previous research by indicating that SFA improves confrontational naming ability and may benefit word retrieval in discourse production of closed-set contexts.
