Functional connectivity of the posterior cingulate cortex in autism spectrum disorder.

The purpose of this study was to assess the functional connectivity of the posterior cingulate cortex in autism spectrum disorder (ASD). We used resting-state functional magnetic resonance imaging (rsfMRI) brain scans of adolescents diagnosed with ASD and a neurotypical control group. The Autism Brain Imaging Data Exchange (ABIDE) consortium was utilized to acquire data from the University of Michigan (145 subjects) and data from the New York University (183 subjects).

Prevalence of hearing loss in college students: a meta-analysis.

Introduction: Hearing loss among college students, specifically noise-induced hearing loss (NIHL), appears to be increasing. This may be particularly challenging for this population as college students are required to listen to lectures in classrooms that may have suboptimal listening environments. College-aged musicians are at a particularly high risk due to repeated and extended exposure to loud noise.

Semantic Aspects of Verb Production in Various Discourse Tasks in People With Nonfluent Aphasia.

Purpose: The purpose of this study was to investigate how people with nonfluent aphasia produce semantically weighted verbs compared to people without aphasia, as well as how a discourse elicitation task affects verb production in people with nonfluent aphasia and people without aphasia.

Method: This study included 30 people with nonfluent aphasia and 32 age-matched people without aphasia from AphasiaBank. Language samples of five different discourse tasks were obtained and coded for heavy, light, and -copular verbs.

The Effects of Different Sources and Modalities of Stuttering Disclosure on Listeners' Perceptions of a Child Who Stutters.

Introduction: Research reveals the clinical efficacy of both verbal and written stuttering disclosure statements provided by a child who stutters (CWS) and his advocates (i.e., mother or teacher) [Lang Speech Hear Serv Sch.

Hippocampal Functional Connectivity in Parkinson's Disease.

Background: While the hippocampus is not part of the nigrostriatal dopaminergic pathway, influence of Parkinson's disease (PD) on the hippocampus has been consistently implicated. However, it is not clear how the hippocampal changes contribute to the pathology of PD.

Objectives: We aimed to elucidate the physiological changes of the hippocampus in its orchestration with the rest of the brain.

Disrupted functional connectivity of the primary auditory cortex in autism.

Autism Spectrum Disorder (ASD) has been found to influence hearing and sensory integration, while brain functional connectivity in ASD has been repeatedly shown to be atypical. However, functional connectivity of the auditory cortex in ASD has not been well studied. In the current study, we used resting-state functional magnetic resonance imaging data, provided by the Autism Brain Imaging Data Exchange (ABIDE), to examine functional connectivity of the primary auditory cortex in ASD.

The Effects of Written Stuttering Disclosure on the Perceptions of a Child Who Stutters.

Purpose This study measured between-groups differences in perceived speech skills and personality characteristics of a 12-year-old male child who stutters (CWS) as a function of a written factual stuttering disclosure statement, delivered by the CWS, his "mother," or his "teacher." Method Four hundred twenty-four college-age adults were assigned to one of four groups, including three experimental groups (i.e.

Bilinguals who stutter: A cognitive perspective.

Purpose: Brain differences, both in structure and executive functioning, have been found in both developmental stuttering and bilingualism. However, the etiology of stuttering remains unknown. The early suggestion that stuttering is a result of brain dysfunction has since received support from various behavioral and neuroimaging studies that have revealed functional and structural brain changes in monolinguals who stutter (MWS).

Estimates of functional cerebral hemispheric differences in monolingual and bilingual people who stutter: dichotic listening paradigm.

Recent studies indicate functional cerebral hemispheric processing differences between monolinguals and bilinguals who stutter, as well as monolinguals and bilinguals who do not stutter. Eighty native German speakers, half of whom were also proficient speakers of English as a second language (L2), were assessed on a dichotic listening paradigm using CV syllables as stimuli. The participants were organised into four different groups according to speech status and language ability: 20 monolinguals who stutter, 20 bilinguals who stutter, 20 monolinguals who do not stutter, and 20 bilinguals who do not stutter.

Visuospatial and Verbal Short-Term Memory Correlates of Vocabulary Ability in Preschool Children.

Background: Recent studies indicate that school-age children's patterns of performance on measures of verbal and visuospatial short-term memory (STM) and working memory (WM) differ across types of neurodevelopmental disorders. Because these disorders are often characterized by early language delay, administering STM and WM tests to toddlers could improve prediction of neurodevelopmental outcomes. Toddler-appropriate verbal, but not visuospatial, STM and WM tasks are available.

Estimates of functional cerebral hemispheric differences in monolingual and bilingual people who stutter: Dual-task paradigm.

The inter-relationship of stuttering and bilingualism to functional cerebral hemispheric processing was examined on a dual-task paradigm. Eighty native German (L1) speakers, half of whom were sequential bilinguals (L2 = English), were recruited. The participants (mean age = 38.

Estimates of functional cerebral hemispheric differences in monolingual and bilingual people who stutter: Visual hemifield paradigm.

The relationship between stuttering and bilingualism to functional cerebral hemispheric processing was examined using a visual hemifield paradigm. Eighty native German speakers, half of whom were also proficient speakers of English as a second language (L2), were recruited. The participants were organised into four different groups according to speech status and language ability: 20 monolinguals who stutter, 20 bilinguals who stutter, 20 monolinguals who do not stutter, and 20 bilinguals who do not stutter.
