Aim: There is often a gap between the ideal of involving older persons iteratively throughout the design process of digital technology, and actual practice. Until now, the lens of ageism has not been applied to address this gap. The goals of this study were: to voice the perspectives and experiences of older persons who participated in co-designin...

Technology acceptance models associate older age with lower intention to use digital technology although this assumption is often stereotypically-based and not sufficiently tested with older persons. This study investigated the association of ageism (rather than chronological age) with behavioral intention and actual use of technology within the th...

Purpose This case study is presented to inform the reader of potential speech, language, cognitive, and emotional characteristics in preadolescent cluttering. Method This case study describes a 10-year-old boy who started to clutter during preadolescence. The case illustrates that, in some adolescents, cluttering can co-occur with temporary stutte...

Background and objectives: Involving older persons in the design process of digital technology (DT) promotes the development of technologies that are appealing, beneficial and used. However, negative discourse on aging and ageism are potential underlying factors that could influence which and how DTs are designed and how older persons are involved...

Background Digital technologies (DTs) for older adults focus mainly on health care and are considered to have the potential to improve the well-being of older adults. However, adoption rates of these DTs are considered low. Although previous research has investigated possible reasons for adoption and acceptance of DT, age-based stereotypes (eg, tho...

Purpose Among the best strategies to address inadequate speech monitoring skills and other parameters of communication in people with cluttering (PWC) is the relatively new but very promising auditory–visual feedback (AVF) training (van Zaalen & Reichel, 2015). This study examines the effects of AVF training on articulatory accuracy, pause duration...

Digital technology holds a promise to improve older adults’ well-being and promote ageing in place. However, there seems to be a discrepancy between digital technologies that are developed and what older adults actually want and need. Ageing is stereotypically framed as a problem needed to be fixed, and older adults are considered to be frail and i...

Purpose The purpose of this paper is to focus on ethical and judicial themes related to technology and the older adults. Design/methodology/approach Different consecutive phases in technology design and allocation will be discussed from a range of perspectives. Findings Longevity is one of the greatest achievements of contemporary science and a r...

In 10 years since the ICA’s creation, it keeps growing in membership, in the breadth of initiatives and in the variety of scientific discoveries in the area of cluttering. A microcosm of international collaboration among 20 researchers and speech therapists from 18 countries in Africa, Asia, Europe (East and West), the Middle East, North America, a...

Real-time location systems (RTLS) can be implemented in aged care for monitoring persons with wandering behaviour and asset management. RTLS can help retrieve personal items and assistive technologies that when lost or misplaced may have serious financial, economic and practical implications. Various ethical questions arise during the design and im...

Een vertraagde en verstoorde taal- en spraakontwikkeling is een belangrijk onderdeel van het downsyndroom-gedragsfenotype. De taalontwikkeling wordt geassocieerd met negen neurosociocognitieve kerndomeinen, welke alle van invloed zijn op en een bijdrage leveren aan taalontwikkeling. Onderzoek naar de achterblijvende woordenschatontwikkeling bij kin...

Purpose: There is a lack of longitudinal data on predictors of vocabulary development in children with Down syndrome (DS). In typically developing children, many internal and external predictors of vocabulary development have been determined before. The purpose of the present study was to investigate the role of these variables in the receptive and...

Purpose Until now, little has been known about the prevalence of “pure” cluttering in a general population. This study sheds light on the prevalence of cluttering in populations of normally developing pre-adolescents in the Netherlands and Germany who do not stutter or have other communication disorders. Method 304 adolescents (Netherlands, n=219/...

The aim of this study was to develop a core vocabulary list for young children with intellectual disabilities between 2 and 7 years of age because data from this population are lacking in core vocabulary literature. Children with Down syndrome are considered one of the most valid reference groups for researching developmental patterns in children w...

The expressive vocabulary of children with Down Syndrome (DS) is generally measured with parental reports, such as the Communicative Development Inventory (CDI), given that standardized tests for assessing vocabulary levels may be too difficult for most young children with DS. The CDI provides important insight into the parents’ perception of their...

Enhancing communication performance skills may help children with Down Syndrome (DS) to expand their opportunities for participation in daily life. It is a clinical challenge for speech-language pathologists (SLP) to disentangle various mechanisms that contribute to the language and communication problems that children with DS encounter. Without cl...

Binnen het Raak Pro project ‘Praten kan ik niet …, maar communiceren wil ik wel’ hebben we onderzoek gedaan naar het gebruik van Communicatie Ondersteunende Hulpmiddelen (COH) bij kinderen/jongeren met ernstige communicatieve en meervoudige beperkingen. Het ging om kinderen/jongeren die niet, nauwelijks of zeer slecht verstaanbaar spreken vanwege h...

This article presents a variety of treatment approaches based on an understanding of four components of communication, and describes cluttering intervention focusing on problem identification, speech rate reduction, appropriate pausing, appropriate monitoring, and addressing story narrating skills. Therapeutic considerations, taking into account th...

Le bredouillement est un trouble de la fluence de la parole dans lequel les personnes ne peuvent ajuster leur parole aux demandes syntaxiques et phonologiques de la situation (Van Zaalen, 2009). Cet article expose les causes du bredouillement en présentant les processus sous-jacents de la production du langage en lien avec un débit de parole anorma...

In individuals with an intellectual disability, speech dysfluencies are more common than in the general population. In clinical practice, these fluency disorders are generally diagnosed and treated as stuttering rather than cluttering. To characterise the type of dysfluencies in adults with intellectual disabilities and reported speech difficulties...

This article presents the highlights of an International Cluttering Association (ICA) international initiative featuring ten experts in fluency disorders from various countries, describing the historical and current state of awareness, research, diagnosis, and treatment of cluttering across countries and continents. In addition, authors discuss the...

The purpose of this study was to answer the question what influences consumer satisfaction and how satisfaction is associated with use or non-use of the Ankle Foot Orthosis (AFO). For this goal an specially designed 'Design in Orthopaedic Engineering Questionnaire for Usability Evaluation of Orthoses' (DOE-quest) was used to answer whether the resu...

In the current study, we investigated the contribution of lateral movement to articulatory (in)stability. Using an optical 3D movement analysis system, articulographic data on jaw movements were collected on the reiterated productions of the words /spa:/ and /pa:s/ (consisting of the same sequence of speech sounds, but with a different syllabic str...

The primary objective of this paper is to determine to what extent disturbances in the fluency of language production of children who clutter might be related to, or differ from difficulties in the same underlying processes of language formulation seen in children with learning disabilities. It is hypothesized that an increase in normal dysfluencie...

Unlabelled: Speech-language pathologists generally agree that cluttering and stuttering represent two different fluency disorders. Differential diagnostics between cluttering and stuttering is difficult because these disorders have similar characteristics and often occur in conjunction with each other. This paper presents an analysis of the differ...

The primary objective of this article is to study whether an assessment instrument specifically designed to assess speech motor control on word level productions would be able to add differential diagnostic speech characteristics between people who clutter and people who stutter. It was hypothesized that cluttering is a fluency disorder in which sp...

This study had the two following objectives: (1) clinical, diagnostic classification of the syndrome of cluttering and particularly the difference in symptomatology between cluttering and stuttering and between cluttering and speaking problems associated with learning disability; (2) to contribute to a (neurolinguistic) model of cluttering that pro...

Abstract Speech-language pathologists generally agree that cluttering and stuttering represent two different fluency disorders.
