Purpose: The adaptation effect in stuttering, traditionally described as the reduction of stuttering moments over repeated readings, provides a context to investigate fluency facilitation as well as a relatively controlled means of comparing fluent speech in the immediate vicinity of words that were stuttered versus fluently produced. Acoustic…

Background: Children who stutter have the right to express their views and be heard. However, in research on stuttering, attention tends to focus mainly on parental and adult perspectives. By actively engaging with children's viewpoints, we can enhance our understanding of their distinct needs and capabilities. This, in turn, enables the…

Background: Multiple sclerosis (MS) is an autoimmune disease that attacks the central nervous system and has several subtypes. The disease pathophysiology includes damage to the myelin in the brain and spinal cord, manifesting in a wide range of neurological symptoms and impacting patients' physical, psychological, social, and communication…

Background: Assessing spoken discourse during aphasia clinical examination is crucial for diagnostic and rehabilitation purposes. Recent approaches have been developed to quantify content word fluency (CWF) and informativeness of spoken discourse without the need to perform time-consuming transcription and coding. However, the accuracy of these…

Background: In everyday communication, word retrieval is semantically driven. A similar processing mechanism can be assumed for category fluency tasks. In contrast, in phonemic fluency tasks or rhyme production, the retrieval process must be based on the word form. In phonemic fluency, executive and language functions have been discussed as…

Background: Verbal fluency tests (VFT) are highly sensitive to cognitive deficits. Usually, the score on VFT is based on the number of correct words produced, yet it alone gives little information regarding underlying test performance. The implementation of different strategies (cluster and switching) to perform efficiently during the tasks…

Background: Narrative discourse, or storytelling, is used in daily conversation and requires higher-level language and social communication skills that are not always captured by standardised assessments of language. Many autistic individuals and individuals with fetal alcohol spectrum disorders (FASD) have difficulties with both social…

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: Although considerable research has been conducted on post-COVID-19 syndrome (PCS), cognitive symptoms, particularly those related to language, are still not well understood. Aims: To provide a detailed quantitative and qualitative analysis of language performance in PCS patients using a comprehensive set of semantic and verbal…

Background: Previous studies on language production in normal ageing have primarily focused on distinct dimensions of older adults' spoken language performance, such as fluency and complexity. However, little attention has been paid to the complex, interconnected relations between these dimensions. Additionally, older adults have been treated as a…

Background: Over 50% of individuals with aphasia face ongoing word-finding issues. Studies have found phonologically oriented therapy helpful for English speakers, but this has not yet been studied in French. It is essential to assess the effectiveness of such a therapy in French, considering the distinct linguistic typologies between both…

Background: Children with dyslexia and/or developmental language disorder (hereafter children with DDLD) have been reported to retrieve fewer words than their typically developing (TD) peers in semantic fluency tasks. It is not known whether this retrieval difficulty can be attributed to the semantic structure of their lexicon being poor or,…

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: Cluttering is a fluency disorder characterized by an abnormally fast or irregular speech delivery rate along with disfluencies that are frequent but are not judged to be stuttering. Data on cluttering prevalence in the general population are scarce, as well as its association with psychological well-being indices, such as anxiety, and…

Background: Although previous research studies have defined several prognostic factors that affect cognitive-communication performance in patients with all traumatic brain injury (TBI) severity, little is known about what variables are associated with cognitive-communication impairment in complicated mild TBI (mTBI) specifically. Aims: To…
