Presents a new set of experimental data from brain-damaged aphasic patients as well as from normal individuals on the processing of two nominals suffixes in Japanese--"-sa" and "-mi." (Author/VWL)

Proposes that the causal mechanisms of recovery patterns in bilingual aphasia can be partially revealed by combining neuropsychological and neuroimaging methods. Reviews potentials and limitations associated with functional neuroimaging experiments on normal and neurologically impaired patients and discusses different levels of description…

Phonological theories have raised the notion of a universally preferred syllable type which is defined in terms of its sonority structure (e.g., Clements, 1990). Empirical evidence for this notion has been provided by distributional analyses of natural languages and of language acquisition data, and by aphasic speech error analyses. The present…

The present case continues the series of anomia treatment studies with contextual priming (CP), being the second in-depth treatment study conducted for an individual suffering from semantically based anomia. Our aim was to acquire further evidence of the facilitation and interference effects of the CP treatment on semantic anomia. Based on the…

The present study investigated the abilities of left-hemisphere-damaged (LHD) non-fluent aphasic, right-hemisphere-damaged (RHD), and normal control individuals to access, in sentential biasing contexts, the multiple meanings of three types of ambiguous words, namely homonyms (e.g., ''punch''), metonymies (e.g., ''rabbit''), and metaphors (e.g.,…

The disadvantage in producing the past tense of regular relative to irregular verbs shown by some patients with non-fluent aphasia has been alternatively attributed (a) to the failure of a specific rule-based morphological mechanism, or (b) to a more generalised phonological impairment that penalises regular verbs more than irregular owing to the…

The current study examines how patients with aphasia access the meanings of idioms during spoken sentence comprehension. In our experiment, we had 4 subjects whose native language is German: 2 left-hemisphere damaged patients (Wernicke's and global aphasia); 1 right-hemisphere damaged patient; and 1 age-matched healthy speaker. Ambiguous…

We report the performance of two aphasic patients in a morphological transformation task. Both patients are Spanish-Catalan bilingual speakers who were diagnosed with agrammatic Broca's aphasia. In the morphological transformation task, the two patients were asked to produce regular and irregular verb forms. The patients showed poorer performance…

Activation studies in patients with aphasia due to stroke or tumours in the dominant hemisphere have revealed effects of disinhibition in ipsilateral perilesional and in contralateral homotopic cortical regions, referred to as collateral and transcallosal disinhibition. These findings were supported by studies with selective disturbance of…

We report the case of a patient who showed a marked deficit in compound reading after almost complete recovery from his aphasic disturbances. Omission of one of the two compound components was his most frequent type of error. The patient also produced many paraphasias, which always respected the compound structure of the target. Similar errors…

In a series of experiments, the effect of white noise distortion and talker variation on lexical access in normal and Broca's aphasic participants was examined using an auditory lexical decision paradigm. Masking the prime stimulus in white noise resulted in reduced semantic priming for both groups, indicating that lexical access is degraded by…

Purpose: To examine reductions in performance on auditory tasks by aphasic and neurologically intact individuals as a result of concomitant magnetic resonance imaging (MRI) scanner noise. Method: Four tasks together forming a continuum of linguistic complexity were developed. They included complex-tone pitch discrimination, same-different…

Purpose: In this study, the authors explore a method of measuring physiologic and perceived stress in individuals with aphasia by investigating salivary cortisol reactivity and subjectively perceived stress in response to a standardized linguistic task. Method: Fifteen individuals with aphasia and 15 age-matched healthy controls participated in a…

Background: Friedreich's ataxia is one of the most common hereditary disorders of the nervous system. Dysarthria is a pervasive symptom of Friedreich's ataxia, yet the clinical presentation of speech symptoms remains poorly understood, leaving clinicians without the evidence required to develop therapy interventions. Aims: The research reported…

This report presents the results of two studies in the area of telecommunication for people with aphasia and mental retardation in Sweden. A brief outline of the use of still picture telephones for picture based distance communication is presented. Overall, still picture telephones were effective as a communication aid for people with either…
