“…88,89 For the non-vocal group, it is imperative to provide augmentative and alternative communication as early as possible. Otherwise they might be seriously hampered in their development of communication and language and have severely restricted opportunities for interaction and participation, 90 which in turn might have negative cascading effects on their social, academic, emotional, and cognitive development.…”

PVL Periventricular leukomalaciaChildren with cerebral palsy (CP) have an increased risk of cognitive impairments. This narrative review of the literature discusses assessment of cognition in children with CP, presents the most salient characteristics of cognitive functioning pertaining to each subtype, and discusses the relationships between brain injury, functioning, and intervention from a developmental perspective. A search for original studies of cognitive functioning in children with different subtypes of CP was performed. The search resulted in 81 unique hits. There were few studies with a representative sample of children with CP where all participants were individually assessed. Cognitive functioning in children with the most severe motor impairments were often assumed and not assessed. Furthermore, there was a confounding of IQ below 70 and intellectual disability, possibly leading to an overestimation of the prevalence of intellectual disability. Longitudinal neuropsychological studies, including also very young children and those with the most severe speech and motor impairments, as well as intervention studies, are called for.

“…Rather, participants favoured more abstract methods of organisation (taxonomic and semantic-syntactic) and graphical symbols that require more grammar (pictographs, ideographs and text). Preferences for abstract methods of organisation and symbols requiring more grammar may be interpreted as an unfounded55 belief that motivated children will be better able to use more complex AAC systems. An alternative and by no means mutually exclusive interpretation is that lack of motivation requires an AAC system involving familiar cues from their everyday environment.…”

Finding the best fit: examining the decision-making of augmentative and alternative communication professionals in the UK using a discrete choice experiment

et al. 2019

Strengths and limitations of this study► This was the first discrete choice experiment (DCE), and only the second stated preference study in the field of augmentative and alternative communication (AAC). ► The study used unusual and innovative methodology by (1) using a Best-worst Scaling case 1 study in attribute selection, (2) having AAC system choices be made in the context of a child vignette formed from a set of attributes and (3) introducing a new measure termed relative interaction attribute importance to interpret results. ► Child vignettes were relatively simple, and a single vignette could represent children with very different needs. ► In some ways, the DCE task differed from how augmentative and alternative professionals make decisions in practice. AbStrACtObjectives Many children with varied disabilities, for example, cerebral palsy, autism, can benefit from augmentative and alternative communication (AAC) systems. However, little is known about professionals' decision-making when recommending symbol based AAC systems for children. This study examines AAC professionals' preferences for attributes of AAC systems and how they interact with child characteristics.Design AAC professionals answered a discrete choice experiment survey with AAC system and child-related attributes, where participants chose an AAC system for a child vignette.Setting The survey was administered online in the UK.Participants 155 UK-based AAC professionals were recruited between 20 October 2017 and 4 March 2018.Outcomes The study outcomes were the preferences of AAC professionals' as quantified using a mixed logit model, with model selection performed using a step-wise procedure and the Bayesian Information Criterion. results Significant differences were observed in preferences for AAC system attributes, and large interactions were seen between child attributes included in the child vignettes, for example, participants made more ambitious choices for children who were motivated to communicate using AAC, and predicted to progress in skills and abilities. These characteristics were perceived as relatively more important than language ability and previous AAC experience.Conclusions AAC professionals make trade-offs between attributes of AAC systems, and these trade-offs change depending on the characteristics of the child for whom the system is being provided.

“…Perhaps the most researched area in AAC software design has been in the area of physical access to technology. People who use AAC technology often have severe physical impairments resulting in slow access due to poor hand function (von Tetzchner ). Individuals for whom direct access is not possible often use a scanning interface which is operated using a single switch (e.g., a head‐switch mounted to the wheelchair headrest); the interface iteratively highlights rows of icons until the row containing the right icon is reached, at which point the individual presses a switch—the system then iteratively highlights icons in the selected row until the switch is pressed again.…”

Telling tales: unlocking the potential of AAC technologies

Augmentative and alternative communication (AAC) has been transformed by the social media revolution made possible by the emergence of mobile technology. The cumbersome dedicated devices of the 1970s have evolved into a burgeoning AAC app industry. However, the limited use and abandonment of AAC technologies remains high. Unlocking the untapped potential of technology requires a paradigm shift in the design of AAC technologies by building systems that minimize the cognitive load placed on users, adapting to their individual physical and language needs. Telling Tales shares insights and stories of how the combination of user‐centred design, interdisciplinary research and the application of intelligent computing is providing a vision of future generations of AAC technologies.
