In this functional magnetic resonance imaging (fMRI) study, we investigated the influence of two task (lexical decision, LDT; phonological decision, PDT) on activation in Broca's region (left Brodmann's areas [BA] 44 and 45) during the processing of visually presented words and pseudowords. Reaction times were longer for pseudowords than words in LDT but did not differ in PDT. By combining the ...

Children's early language exposure impacts their later linguistic skills, cognitive abilities, and academic achievement, and large disparities in language exposure are associated with family socioeconomic status (SES). However, there is little evidence about the neural mechanisms underlying the relation between language experience and linguistic and cognitive development. Here, language experie...

Introduction: The results of clinical studies about the severity of post stoke dementia patients are limited in Korea. We investigate clinical factors related to severity of dementia and to inspect the clinical factors related to the progression of dementia severity. Methods: The patients who visited the hospital by first time between March 2010 and September 2012, among the patients with post ...

This study aimed to verify the existence of a double aphasia/apraxia dissociation. Apraxic patients without aphasia and aphasic patients without apraxia were included in a consecutive series of patients with cortical or subcortical CT documented vascular lesions in the left hemisphere. Of 699 patients, 10 were found to be apraxic but not aphasic and 149 aphasic but not apraxic. These findings i...

Knowledge about the recovery of language functions in bilingual aphasic patients who suffer from left-hemispheric stroke is scarce. Here, we present the case of an early bilingual patient (German/French) with chronic aphasia. Functional magnetic resonance imaging (fMRI) was used to investigate neural correlates of language performance during an overt picture naming task in German and French (a)...

Sentence production difficulties are a common feature of aphasia. The aim of the current study was to investigate the processes involved in sentence production and to identify whether consistent patterns of difficulties are associated with non-fluent and fluent aphasic speech. An analysis of sentence production was designed which described thematic, phrasal and morphological structure. The sent...

INTRODUCTION The aim of this study is contribute to clinical practice of bilinguals around the globe, as well as to add to our understanding of bilingual aphasia processing, by analysing confrontation naming data from four Afrikaans/English bilingual individuals with acquired aphasia due to a left hemisphere stroke. METHODS This is a case series analysis of four Afrikaans/English bilingual ap...

For more than 100 years, clinicians have noted that patients with nonfluent aphasia are capable of singing words that they cannot speak. Thus, the use of melody and rhythm has long been recommended for improving aphasic patients' fluency, but it was not until 1973 that a music-based treatment [Melodic Intonation Therapy (MIT)] was developed. Our ongoing investigation of MIT's efficacy has provi...

Since Pollock’s 1989 paper, much linguistic argumentation has been mounted in favor of the split inflection hypothesis. This paper presents evidence from a neuropsychological angle in support of this hypothesis. Given that agrammatic aphasic patients demonstrate a selective deficit in the syntactic domain, it is tempting to look for impairment patterns that pertain to issues debated in current ...

PURPOSE Kiran and colleagues (Kiran, 2007, 2008; Kiran & Johnson, 2008; Kiran & Thompson, 2003) previously suggested that training atypical examples within a semantic category is a more efficient treatment approach to facilitating generalization within the category than training typical examples. In the present study, the authors extended previous work examining the notion of semantic complexit...
