Describing the Motor Skills of Young Children with Developmental Delays Before and After Participating in an Augmented or Non-Augmented Language Intervention

Whitfield, Ani S 06 March 2012 (has links)
This study described the effect of a non-augmented (Spoken Communication, SC) and two augmented language interventions (Augmented Communication-Input, AC-I or Augmented Communication-Output, AC-O) on the upper-body, gross and fine motor skills of toddlers at the onset and conclusion of the intervention. The data presented are from a longitudinal study by Romski, Sevcik, Adamson, Cheslock, Smith, Barker, & Bakeman (2010). Three standardized assessments and five observational measures examined the participants' motor skills used to activate the speech generating device (SGD), language abilities and outcomes. The AC-O intervention decreased physical prompting, increased error-free symbol activations, and increased developmentally appropriate gross and fine motor use. An augmented intervention that utilizes a SGD may facilitate both language and motor development through the combination of the communicative goals and increased motor learning opportunities when accessing the SGD device.

Configurações para métodos de acesso por escaneamento

Mariano, Daniel Teodoro Gonçalves 25 April 2016 (has links)
O emprego de tecnologias de acesso a comunicação, baseados em métodos de acesso por escaneamento, viabiliza novas oportunidades de comunicação para indivíduos com disfunção motora severa. Um dos exemplos mais comuns desse tipo de tecnologia é o teclado virtual operado por varredura. Teclados virtuais são frequentemente utilizados como dispositivos de comunicação aumentativa e alternativa por indivíduos com restrições motoras graves e que apresentam comprometimento da fala e da escrita. São compostos por uma matriz de teclas e simulam a operação de um teclado físico para a composição de mensagens. Uma das limitações desses sistemas é o baixo desempenho que possuem. Taxas de comunicação lentas e a considerável ocorrência de erros são alguns dos problemas que usuários desses dispositivos sofrem durante o uso diário. O desenvolvimento e a avaliação de novas estratégias em comunicação aumentativa e alternativa são essenciais para a melhoria das oportunidades de comunicação dos usuários que fazem uso desse tipo de tecnologia. Neste sentido, este trabalho explora diferentes estratégias para aumentar essa taxa de comunicação e reduzir os erros cometidos por seus usuários. Análises computacionais e práticas foram executadas para a avaliação das estratégias propostas. / The use of access technologies for communication, based on scanning methods, enables new communication opportunities for individuals with severe motor dysfunction. One of the most commom examples of this type of technology is the single switch scanning. Single switch scanning keyboards are often used as augmentative and alternative communication devices for inidividuals with severe mobility restrictions and with compromised speech and writing. They consist of a matrix of keys and simulate the operation of a physical keyboard to write messages. One of the limitations of these systems is their low performance. Low communication rates and considerable errors ocurrence are some of the few problems that users of these devices suffers during daily use. The development and evaluation of new strategies in augmentative and alternative communication are essential to improve the communication opportunities of user who make use of such technology. Thus, this work explores different strategies to increase communication rate and reduce user’s mistakes. Computational and practical analysis were performed for the evaluation of proposed strategies. / Dissertação (Mestrado)
