Background: Speech differences may occur between motor subtypes of Parkinson's disease (PD), but the literature remains limited. Aims: Examine speech characteristics in individuals with PD across the tremor-dominant, nontremor-dominant and mixed subtypes comparing to healthy controls. Methods and Procedures: A total of 115 individuals with PD were…

Background: Verbal fluency tasks are routinely used in clinical assessment and research studies of aphasia. People with aphasia produce fewer items in verbal fluency tasks. It remains unclear if their output is limited solely by their lexical difficulties and/or has a basis in their executive control abilities. Recent research has illustrated that…

Background: The detection and description of language impairments in neurodegenerative diseases like Alzheimer's Disease (AD) play an important role in research, clinical diagnosis and intervention. Various methodological protocols have been implemented for the assessment of morphosyntactic abilities in AD; narrative discourse elicitation tasks…

Background: Bilingualism is widespread and being bilingual is more common than being monolingual. The lifelong practice bilinguals receive from managing two languages seems to lead to a cognitive benefit. Conversely, bilingualism seems to affect language ability negatively due to less use of each known language. Aims: This systematic review aims…

Background: Aphasia is often accompanied by impairment of non-language cognitive functions. Assessment of cognitive capacity in people with aphasia (PWA) with standard neuropsychological methods may be problematic due to their language difficulties. Numerous experimental studies indicate that P300 may be considered as an index of cognitive…

Background and Aims: This longitudinal study investigated the language skills, phonological working memory and lexical-tone perception of Mandarin-speaking late-talkers (LTs) and those with typical language development (TLD) at 27 months, while also examining their connections with novel word-referent mapping (W-R mapping) through eye-tracking at…

Background: Persons with Parkinson's disease (PD) frequently report word-finding difficulties. Many of the established tests are, however, insufficient in detecting mild cases of such symptoms. Results from earlier research have suggested that controlled oral word association tests (COWATs) with high demands on cognitive processing resources could…

Background: Although long-term social challenges following traumatic brain injury (TBI) are well documented, the challenges of establishing new relationships following TBI are less understood. Aims: To examine how the type of non-verbal cues produced by an unfamiliar communication partner impacts feelings of relationship closeness by people with…

Background: Until today, there is no satisfying explanation for why one language may recover worse than another in differential bilingual aphasia. One potential explanation that has been largely unexplored is that differential aphasia is the consequence of a loss of language control rather than a loss of linguistic representations. Language…

Background: Deficits in the ability to use language in social contexts, including storytelling skills, are observed across the autism spectrum. Development in machine-learning approaches may contribute to clinical psychology and psychiatry, given its potential to support decisions concerning the diagnosis and treatment of psychiatric conditions…

Background: Teachers and clinicians may struggle to provide early identification to support multilingual children's language development. Dynamic assessments are a promising approach to identify and support children's language development. Aims: We developed and studied a novel word learning task that is dynamic and language neutral. It makes use…

Background: Alzheimer's disease is characterized by macrolinguistic changes. This decline is often analyzed with quantitative scales. Aims: To analyze discourse production in early Alzheimer's disease (AD) and to identify qualitative markers of macrolinguistic decline. Methods & Procedures: We analyzed macrolinguistic features of a clinical…

Background: German participles are formed by a co-occurrence of prefixation and suffixation. While the acquisition of regular and irregular suffixation has been investigated exhaustively, it is still unclear how German children master the prosodically determined prefixation rule (prefix "ge-"). Findings reported in the literature are…

Background: The ability to generate words that follow certain constraints, or verbal fluency, is a sensitive indicator of neurocognitive impairment, and is impacted by a variety of variables. Aims: To investigate the effect of post-stroke aphasia, elicitation category and linguistic variables on verbal fluency performance. Methods &…

Background: Many children with neurodevelopmental disorders such as autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD) or developmental language disorder (DLD) have difficulty recognizing and understanding emotions. However, the reasons for these difficulties are currently not well understood. Aims: To compare the…
