Background: Recent evidence suggests that speech substantially changes in ageing. As a complex neurophysiological process, it can accurately reflect changes in the motor and cognitive systems underpinning human speech. Since healthy ageing is not always easily discriminable from early stages of dementia based on cognitive and behavioural…

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: Prelinguistic communication complexity refers to the use of different communication forms such as eye gaze, gestures and vocalisations and the degree to which these forms are coordinated and how directed to a communication partner. To date, little is known about the relationship between prelinguistic communication complexity and…

Background: This study reports on new contexts in which formulaic language has been used in the years since 2013 when the last synthesis was carried out. The background presents an old but still useful definition and lists themes under which research was arranged in 2013 and which continue to be used. Aims: This study has a particular emphasis on…

Background: In the past few years there has been a growing interest in the employment of verbal productions as digital biomarkers, namely objective, quantifiable behavioural data that can be collected and measured by means of digital devices, allowing for a low-cost pathology detection, classification and monitoring. Numerous research papers have…

Background: Parents play a central role in the treatment of childhood stuttering. Addressing parental attitudes toward stuttering is helpful therapeutically. The extent to which differences in attitudes toward stuttering exist on the basis of sex, geographical region and parental status (e.g., parent of a stuttering child, parent of a…

Background: The therapeutic process is fraught with various feelings. This research focused on a specific type of negative feeling, namely self-doubt (SD). Aim: To explore and characterize the nature of SD among speech and language therapists (SLTs) (the frequency of SD, situations that trigger SD, emotions and thoughts related to SD, and coping…

Background: Vocabulary scores increase until approximately age 65 years and then remain stable or decrease slightly, unlike scores on tests of other cognitive abilities that decline significantly with age. Aims: To review the findings on ageing-related changes in vocabulary, and to discuss four methodological issues: research design; test type;…

Background: Word retrieval skills change across the lifespan. Permanent alterations in the form of decreased accuracy or increased response time can be a consequence of both normal ageing processes or the presence of acquired and neurodegenerative disorders (e.g., aphasia and dementia). Despite the extensive literature exploring the…

Background: Age is a key factor when dealing with language and speech disorders, as it entails a progressive loss of neuroplasticity even in healthy individuals. Apart from this, ageing also affects our word-retrieval abilities, and thus, our discursive skills, particularly in people suffering from neurodegenerative diseases. Therefore,…

Background: Communication of people with Parkinson's disease (PwPD) is negatively affected. For PwPD with communication difficulties, it is important to use self-assessment tools as a primary assessment approach to evaluate their perspectives on communication. It is also important to evaluate PwPDs with self-assessment scales in order to determine…

Background: Pragmatic language use in general and the use of evaluation devices (EDs) are very important components in everyday communication and expressing thoughts and feelings in narrative production. However, very little is known about the use of evaluative devices in the narratives of Arabic-speaking adolescents, especially those who are deaf…

Background: Children with Tourette syndrome (TS) have historically experienced problems in academic and social settings, yet their language and communication abilities have not been extensively researched. Aims: This scoping review maps the literature on the oral language and social communication abilities of children with TS in order to describe…

Background: The impact of hearing impairment is typically studied in terms of its effects on speech perception, yet this fails to account for the interactive nature of communication. Recently, there has been a move towards studying the effects of age-related hearing impairment on interaction, often using referential communication tasks; however,…

Background: At least 25% of autistic children worldwide have the potential to grow up in a bilingual environment. However, many autistic children are being denied opportunities to access additional languages and the cultural, familial and community connections that come with this. There is little evidence identifying the barriers to language…
