Abstract:

Although this thesis is primarily about aphasia it is not about the linguistic abilities of aphasic individuals <I>per se</I>. Rather, its central topic is concerned with how people who do not have aphasia interact with people who do. Human communication is a process involving interactive and collaborative effort and its success in dependent on the joint responsibility of both partners. If aphasic participants can effectively draw on their non-impaired partner's abilities, then this strategy should not be ignored. The question we need to ask is <I>How does it work?</I> This dissertation attemp

Furthermore this study analyzes the divergences of perspectives between people with aphasia and their relatives and/or caregivers about relevant factors in the life after stroke.

Abstract:

<p> Aphasia is an acquired impairment of language secondary to neurological brain damage commonly seen in stroke, and is defined by impairment to communication through speech and language which can limit participation in work, family, and social settings. Standard aphasia treatment consists of behavioral therapy to restore or compensate for this impairment. Unfortunately, recovery is often incomplete with long-lasting residual communication deficits. </p><p> Enhancing the effects of behavioral therapy has long been a goal of aphasia researchers.

Adaptation to perturbation was examined under compensatory and noncompensatory conditions, in which the degree of mandibular opening posed maximal and minimal interference respectively, with reference to normal articulatory positioning.

Abstract:

Background: Post-stroke depression (PSD) is a common phenomenon and has a negative impact on rehabilitation, recovery and quality of life. About one third of stroke patients suffer communication problems, including aphasia, which is a condition that mainly affects their ability in understanding and/or producing language. The frequency of depressive symptoms in post-stroke aphasia has been difficult to determine as most studies have excluded stroke patients with aphasia due to methodological limitations. As a result, depression remains often under-diagnosed and untreated in these patients. Obje

As a group, the cohort showed an improvement of +6.52 AQ points, yielding an average rate of change of +4.07 AQ points per year. The rate of change was greatest at earlier times post onset (between three months and two years), and improvement was great

The current project provides a novel perspective on sentence comprehension in Broca’s aphasia by expanding the empirical domain both within and beyond narrow syntax.

In particular, we focus on three key linguistic phenomena that arguably involve different language domains, get passive constructions (narrow syntax), ambiguous sentences involving the nomi

Non word responses maintained the normal English distribution of phonemes. Importantly, they also showed greater than chance levels of target relatedness. Analysis of LT's responses to a set of stimuli controlled for their consonant content allowed more detailed investigation of the nature of target and error pho

The conceptual-semantic test-battery uses non-verbal stimuli, such as silhouettes from objects, pantomimes, object colours, and environmental sounds.

These error patterns have been identified in sentence and discourse comprehension and production.

This traditional concept has been contested by late 20th century reports of sensory aphasia, auditory comprehension deficits and poor prognosis in childhood.

Primary Progressive Aphasia (PPA) is a clinical syndrome caused by neurodegenerative disease in which language impairment is the initial and most prominent symptom (Mesulam, 1982). Currently, three variants of PPA are recognized (Gorno-Tempini et al., 2011); the non fluent/agrammatic variant (nfvPPA), the logopenic variant (lvPPA) and the semantic variant (svPPA). Difficulty in conversing is the primary complaint of people with PPA and their carers (Knibb, Woollams, Hodges, & Patterson, 2009).

Researchers have documented a reduction in verbal memory span in individuals with perisylvian stroke resulting in aphasia, but scant data are available regarding the integrity of long-term memory in such individuals. Whereas dissociated memory processes have been documented in nonaphasic populations, characteristic patterns of short- versus long-term memory have not typically been associated with specific lesion sites in aphasic individuals.

Abstract:

Independently proposed linguistic analyses permit us to characterize function words and inflectional morphology as one class. These elements are hypothesized to constitute heads of functional projections. In this thesis, the Head Accessibility Hypothesis is proposed to account for the representations aphasics have of lexical and functional projections. It maintains that, as a consequence of the interactional nature of the modular grammar embodied in the principles and parameters version of Government-Binding theory (Chomsky 1982, 1986), syntactic deficits may be due to problems at the level of

Abstract:

This thesis proposes to lay some of the groundwork for an investigation of the prepositional deficit in aphasia. We observe that (i) the status of the category PREPOSITION is problematic for linguistic theory and (ii) patterns of loss in aphasia do not affect prepositions uniformly. In accordance with the view that such sets of theoretical and aphasiological observations can and must be related, an overview of the structural (linguistic) properties of prepositions, an examination of a compatible sentence processing (psycholinguistic) model, and an exhaustive review of the literature on preposi
