Producing a sentence involves encoding a preverbal message into a grammatical structure by retrieving lexical items and integrating them into a functional (semantic-to-grammatical) structure. Individuals with agrammatism are impaired in this grammatical encoding process. However, it is unclear what aspect of grammatical encoding is impaired and…

Recent work in neuropsychology, clinical aphasiology and neuropharmacology have presented evidence that the causative substrates of recurrent perseveration in adults with aphasia are more recondite and subject to distinct interpretations than originally thought. This article will discuss and evaluate how various proposals from theory, from the…

Several studies have reported improved naming using the semantic feature analysis (SFA) approach in individuals with aphasia. Whether the SFA can be modified and still produce naming improvements in aphasia is unknown. The present study was designed to address this question by using a modified version of the SFA approach. Three, rather than the…

Previous studies have shown the appearance of right-sided language-related brain activity in right-handed patients after a stroke. Non-invasive brain stimulation such as transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) have been shown to modulate excitability in the brain. Moreover, rTMS and…

Purpose: To investigate the hypothesis that vowel production is more variable in adults with acquired apraxia of speech (AOS) relative to healthy individuals with unimpaired speech. Vowel formant frequency measures were selected as the specific target of focus. Method: Seven adults with AOS and aphasia produced 15 repetitions of 6 American English…

This article provides a detailed assessment of patient HT with a history of progressive language deterioration of approximately 6 years presenting now as a fluent jargon aphasic with severe impairment of both speech production and comprehension. Neuropsychological testing of non-verbal cognitive functions showed no impairment, leading to the…

We report the naming performance of a Spanish patient (AQF) suffering from Primary Progressive Aphasia (PPA). AQF's performance revealed a grammatical category-specific deficit, with poorer performance in verb than in noun naming. Furthermore, this dissociation was only present in written naming. Importantly, the patient's dissociation between…

Purpose: To determine the effect of personal relevance and contextualization of images on the preferences and word-picture matching accuracy of people with severe aphasia. Method: Eight adults with aphasia performed 2 experimental tasks to reveal their preferences and accuracy during word-picture matching. The researchers used 3 types of visual…

We illustrate the value of the Bilingual Aphasia Test in the diagnostic assessment of a trilingual speaker post-stroke living in England for whom English was a non-native language. The Comprehensive Aphasia Test is routinely used to assess patients in English, but only in combination with the Bilingual Aphasia Test is it possible and practical to…

As bilingualism becomes less exceptional in the world, and with the growing incidence of stroke and aphasia, a better understanding of how bilingualism affects aphasia recovery is increasingly important. The present study examined the effect of intensive semantic naming therapy in three phases (Spanish, English and mixed) on within- and…

This study sought to discover if an optimum 1 cm[squared] area in the non-damaged right hemisphere (RH) was present, which could temporarily improve naming in chronic, nonfluent aphasia patients when suppressed with repetitive transcranial magnetic stimulation (rTMS). Ten minutes of slow, 1 Hz rTMS was applied to suppress different RH ROIs in…

Purpose: To extend the use of the Spanish Computer-assisted Anomia Rehabilitation Program (CARP-2) for anomia from a single case to a group of 15 people with aphasia. To evaluate whether the treatment is active (Phase 1) for this group (Robey & Schultz, 1998), providing potential explanations as to why. Methods: Fifteen participants with chronic…

In this article, a form of intra-turn projection is analyzed where the first component of a compound turn-constructional unit (TCU) containing a phrase, such as "the one (who/that)," projects that a reference (e.g., to a person or to an entity, such as a film) is due to be produced in a later component. This type of utterance is described by…

Selective impairments of word-class retrieval skills have been extensively reported in the literature. Such findings posit that the conceptual knowledge is represented in specific categories, with possibly different neural representations. Although there are myriads of such findings in the literature, similar reports are scanty from the Indian…

Purpose: Damage to left perisylvian cortex often results in impaired phonological processing abilities with written language profiles consistent with phonological alexia and phonological agraphia. The purpose of this article was to examine a behavioral treatment sequence for such individuals intended to strengthen phonological processing and links…
