Augmentative and Alternative Communication最新文献

Significant advances have been made in interventions to maintain communication and personhood for individuals with neurodegenerative conditions. One innovation is Message Banking, a clinical approach first developed at Boston Children's Hospital (BCH). This paper outlines the Message Banking process as implemented at BCH, which includes the option of "Double Dipping," where banked messages are mined to develop personalized synthesized voices. More than a decade of experience has led to the evolution of six core principles underpinning the BCH process, resulting in a structured introduction of the associated concepts and practices with people with amyotrophic lateral sclerosis (ALS) and their families. These principles highlight the importance of assigning ownership and control of the process to individuals with ALS and their families, ensuring that as a tool it is empowering and offers hope. Changes have been driven by feedback from individuals who have participated in the BCH process over many years. The success of the process has recently been extended through partnerships that allow the recorded messages to be used to develop individual personalized synthetic voices to complement banked messages. While the process of banking messages is technically relatively simple, the full value of the process should be underpinned by the values and principles outlined in this tutorial.

Families are the most significant communication partners for an individual with complex communication needs. Even though family-centered approaches are recommended to support augmentative and alternative communication (AAC) services for an individual, it is difficult to establish a successful plan that fits each individual's family. A framework for practitioners is proposed to effectively obtain and understand information about a family's unique dynamics as part of service delivery to positively impact AAC device uptake and long-term use. The goal of using this model is to minimize the disruption to the family while maximizing the integration of the AAC system. This paper proposes and illustrates a framework to enrich AAC services through the integration of several theoretical models of family systems theory, family paradigms, and a procedure called the self-created genogram. This paper begins by reviewing ecological family systems theory and family systems to guide and provide a framework to support effective AAC implementation. The process of self-creating genograms is then introduced as a means to obtain a rich perspective on family characteristics and dynamics that is informed by the individual who uses AAC. All of this information allows professionals to provide relevant information and tailor options for the family. As a result, the family is able to make informed decisions about AAC intervention in a manner most consistent with how they typically operate. Finally, we apply this framework to a hypothetical case of a child with autism and complex communication needs across three timepoints (preschool, late elementary/early middle school, and high school/post-secondary transition) to demonstrate how this framework can be used in clinical practice.

Nonvocal alert patients in the intensive care unit (ICU) setting often struggle to communicate due to inaccessible or unavailable tools for augmentative and alternative communication. Innovation of a hand-operated non-touchscreen communication system for nonvocal ICU patients was guided by design concepts including speech output, simplicity, and flexibility. A novel communication tool, the Manually Operated Communication System (MOCS), was developed for use in intensive care settings with patients unable to speak. MOCS is a speech-output technology designed for patients with manual dexterity impairments preventing legible writing. MOCS may have the potential to improve communication for nonvocal patients with limited manual dexterity.

Conversational repair has been found to play a fundamental role in the acquisition of language. This paper describes existing research on conversational repair and its relationship to language learning, whether a first language or a second language, as well as its relevance to augmentative and alternative communication (AAC). A case is made for incorporating prompts to repair in conversation-based language interventions with children learning to use AAC. We argue that interventions targeting linguistic complexity should encourage self-repair in conversation in order to develop linguistic and operational competency as well as increase automaticity when using AAC. Clinical implications and directions for future research are discussed.

Shared reading is an important context for the development of communication, language, and literacy skills in young children. Research conducted with children who require augmentative and alternative communication has indicated that dialogic reading techniques utilized in shared reading can aid in the development of communication skills. One area that has not been investigated is which words children should have access to when engaging in these types of activities. This study reports the results of an investigation focused on the words 5-year-old children without disabilities said during a dialogic reading procedure that occurred with two books, Corduroy and Whistle for Willie. When reading Corduroy and Whistle for Willie, 59 common words said when reading each book accounted for 62.45% and 64.83% of the total words said, respectively. Many of these words were similar to those identified in studies of core vocabulary across a variety of contexts. For Corduroy and Whistle for Willie, 13 and 11 of these 59 words were directly related to the book, respectively. This accounted for approximately 10% of the most commonly used words for each book. The implications of this finding are discussed relative to vocabulary selection for children with complex communication needs during shared reading experiences.

This study evaluated the effectiveness of an embedded naturalistic intervention for teaching augmentative and alternative communication (AAC) application responses to three preschool-aged males with autism spectrum disorder (ASD). Parents were taught to embed opportunities for their child to communicate with a grid-based AAC application during every-day routines such as play or mealtime. Communication targets included requesting objects using two-step taxonomic navigational responses, and requesting assistance, rejecting items, or making social comments/responses using a two-step message-strip response. During intervention, parents used strategies such as time delay, prompting, reinforcement, and device proximity (faded over time) to encourage target responses. Display formats and intervention targets were selected in consideration of prior dynamic assessment results. Effects of intervention were evaluated using a multiple probe across participants design. For functional navigational AAC item requesting, all three participants showed an immediate increase in responding that maintained at high levels. Functional AAC responding for other communicative purposes also increased, but at a more gradual pace. All three participants showed generalized responding when new items were added to displays, and when display pages with a larger array of folders and vocabulary items were introduced. Generalization to labeling tasks was mixed.

For this study, 11 children with moderate to severe autism spectrum disorder (ASD) were given directives containing prepositions in three cue conditions: (a) spoken alone, (b) a short video clip along with spoken cues, and (c) a sequence of three graphic symbols accompanied by spoken cues. Participants followed directives significantly more accurately with the video clip than with spoken cues only, and significantly more accurately with spoken cues only relative to the sequence of graphic symbols. Results suggest that the short video clip along with spoken cues may be an optimal mode for enhancing learners' ability to follow directives containing prepositions. In addition, results reveal three statistically significant correlations between participants' preexisting skills and directive-following accuracy: a positive correlation between spoken preposition preassessment total score and accuracy in the spoken-alone condition; a positive correlation between spoken noun preassessment total score and accuracy in the video-clip condition; and a positive correlation between ASD severity and the need for repetition in the video-clip condition. Results also suggested that, for children with more severe ASD symptoms, the video clips require repetitions so that the relationships illustrated within it can gain more semantic salience. Implications for clinical practice and future research are discussed.
