Lack of insight is a core diagnostic criterion for behavioral variant frontotemporal dementia (bvFTD), and is believed to be intact in the early stages of primary progressive aphasia (PPA). In other neurological conditions, symptom-specific insight has been noted, with behavioral symptoms appearing especially vulnerable to reduced insight.…

In this study we investigated the recovery patterns of language and cognitive functions in patients with post-traumatic language processing deficits and in patients with aphasia following a stroke. The correlation of specific language functions and cognitive functions was analyzed in the acute phase and 6 months later. Significant recovery of the…

This paper examines the relative values of syntactic-semantic relationships in the mental lexicon of aphasic patients, which were tested within syntagmatic and paradigmatic networks of lexical relations. Semantic relations, such as synonymy, antonomy, and hyperonymy, as well as collocational and coordinational syntactic-semantic relations, were…

This paper uses the methodology of conversation analysis (CA) to examine the practice of co-constructed turn and utterance production in impaired communication. An investigation of the conversations between two family dyads, featuring one person with dysarthric speech and one with aphasic language, reveals one way in which single turns and…

Semantic short-term memory (STM) patients have a reduced ability to retain semantic information over brief delays but perform well on other semantic tasks; this pattern suggests damage to a dedicated buffer for semantic information. Alternatively, these difficulties may arise from mild disruption to domain-general semantic processes that have…

This review brings together evidence from a diverse field of methods for investigating sex differences in language processing. Differences are found in certain language-related deficits, such as stuttering, dyslexia, autism and schizophrenia. Common to these is that language problems may follow from, rather than cause the deficit. Large studies…

Lesion studies have demonstrated impairments of specific types of phonological processes. However, results from neuropsychological studies of speech sound processing have been inconclusive as to the role of specific brain regions because of a lack of a one-to-one correspondence between behavioural patterns and lesion location. Functional…

This paper presents the results of a study of the effects of left hemisphere strokes on syntactically-based comprehension in aphasic patients. We studied 42 patients with aphasia secondary to left hemisphere strokes and 25 control subjects for the ability to assign and interpret three syntactic structures (passives, object extracted relative…

The current trend of the WHO that suggests that aphasia assessment and intervention strategies should be directly influenced by outcome goals related to life participation is presented.

The article discusses how adult learning theory can contribute to the success of life participation approaches to aphasia (LPAA) approach to treatment.

Failure to supply inflection is common in adult L2 learners of English and agrammatic aphasics (AAs), who are known to resort to bare verb forms. Among attempts to explain the absence of inflection are competing morphological and phonological explanations. In the L2 acquisition literature, omission of inflection is explained in terms of: mapping…

Five nonfluent aphasia patients participated in a picture-naming treatment that used an intention manipulation (opening a box and pressing a button on a device in the box with the left hand) to initiate naming trials and was designed to re-lateralize word production mechanisms from the left to the right frontal lobe. To test the underlying…

Discourse produced by speakers with aphasia contains rich and valuable information for researchers to understand the manifestation of aphasia as well as for clinicians to plan specific treatment components for their clients. Various approaches to investigate aphasic discourse have been proposed in the English literature. However, this is not the…

Purpose: This systematic review summarizes evidence for intensity of treatment and constraint-induced language therapy (CILT) on measures of language impairment and communication activity/participation in individuals with stroke-induced aphasia. Method: A systematic search of the aphasia literature using 15 electronic databases (e.g., PubMed,…

Despite the increasing number of neuroimaging studies of syntactic gender processing no model is currently available that includes data from visual and auditory language comprehension and language production. This paper provides a systematic review of the neural correlates of syntactic gender processing. Based on anatomical information from…
