The case of an aphasic patient whose spontaneous speech contains very few lexical verbs is reported. Instead of sentences with lexical verbs, the patient produces many (grammatical) copular constructions. He also substitutes lexical verbs with the copula. Although this results in ungrammatical utterances, by doing so, a resemblance of sentence…

We tested the core prediction of the Trace Deletion Hypothesis (TDH) of agrammatic Broca's aphasia, which contends that such patients' comprehension performance is normal for active reversible sentences but at chance level for passive reversible sentences. We analyzed the comprehension performance of 38 Italian Broca's aphasics with verified…

In the present study, a cross-modal semantic priming task was used to investigate the ability of left-hemisphere-damaged (LHD) nonfluent aphasic, right-hemisphere-damaged (RHD) and non-brain-damaged (NBD) control subjects to use a discourse context to resolve lexically ambiguous words. Subjects first heard four-sentence discourse passages ending…

B. Rapp and M. Goldrick (2000) claimed that the lexical and mixed error biases in picture naming by aphasic and nonaphasic speakers argue against models that assume a feedforward-only relationship between lexical items and their sounds in spoken word production. The author contests this claim by showing that a feedforward-only model like WEAVER++…

This study investigated how normal subjects and Broca's and Wernicke's aphasics integrate thematic information incrementally using syntax, lexical-semantics, and pragmatics in a simple active declarative sentence. Three priming experiments were conducted using an auditory lexical decision task in which subjects made a lexical decision on a…

Two fluent aphasics, IG and GL, performed a phonological priming task in which they repeated an auditory prime then named a target picture. The two patients both had selective deficits in word production: they were at or near ceiling on lexical comprehension tasks, but were significantly impaired in picture naming. IG's naming errors included both…

We reanalyzed the data in Drai and Grodzinksy (2005), considering individual patients' responses to different sentence types to be non-independent events. The analyses revealed effects of two of the three factors identified by Drai and Grodzinsky-constituent movement and passive mood. The result is inconsistent with the trace deletion hypothesis;…

Investigations of language processing in aphasia have increasingly implicated performance factors such as slowed activation and/or rapid decay of linguistic information. This approach is supported by studies utilizing a communication system ("SentenceShaper"[TM]) which functions as a "processing prosthesis." The system may reduce the impact of…

Two experiments investigated phonological, derivational-morphological and semantic aspects of grammatical gender assignment in a perception and a production task in German aphasic patients and age-matched controls. The agreement of a gender indicating adjective (feminine, masculine or neuter) and a noun was evaluated during perception in…

This paper investigates stress assignment in Dutch aphasic patients in non-word repetition, as well as in real-word and non-word reading. Performance on the non-word reading task was similar for the aphasic patients and the control group, as mainly regular stress was assigned to the targets. However, there were group differences on the real-word…

This article reports on the linguistic and pragmatic language skills of adults with a diagnosis of autism spectrum disorder (ASD). Seventeen adults (aged 18-67 years) with a diagnosis of ASD were assessed using the Western Aphasia Battery (WAB), the Right Hemisphere Language Battery (RHLB) and the Test of Nonverbal Intelligence-Second Edition…

Precrisis intervention programming can provide the significant others of aphasic older adults with information and experiences which will help them to understand the nature of aphasic communication breakdown, its impact on the individual and family, and the strategies which will enhance communicative interactions and facilitate rehabilitation…

The article describes an approach to aphasia description and intervention based on analysis of speech pauses and hesitations. The concepts of pause, planning, and paraphasia (a language production error involving substitution or replacement) are distinguished. Three case studies illustrate application of the technique.

Treatment of acquired reading disorders are discussed in terms of reading processes, assessment, and external/internal factors affecting comprehension. Treatment methods are distinguished for severely impaired, moderately impaired, and mildly impaired patients. (DB)

Nine aphasia tests were reviewed using seven psychometric criteria appropriate to standardized tests. The need for test manuals to contain a wide range of psychometric information is discussed, and, in particular, the role of subject description in test standardization is emphasized. (Author/CL)
