项目摘要

DESCRIPTION (provided by applicant): The PC-based Communication System (CS) was developed for adults with acquired aphasia. It acts as a "processing prosthesis" by taking spoken message creation off-line and minimizing demands for fast retrieval and working memory. Used as an AAC device, the CS has been shown to enhance aphasics' fluency and grammatical expression in narrative production tasks. Used as a therapy tool, it resulted in improved unaided production after independent practice in the home. This proposal will extend the functionality of the CS by making it possible for the user to transfer CS-generated messages appropriate to specific situations onto a hand-held computer, which can be deployed in situ to supplement or cue language production in real-world, real-time, communication. The intention is to create an AAC device that will not only enable the transfer of information appropriate to these situations, but also will allow the user to demonstrate his or her intellectual competence, which may be obscured by the language disability. An experiment is proposed to evaluate whether and how the enhanced system (CS plus handheld: CS-HH) benefits aphasics' communication of messages prepared in anticipation of simulated service encounters (e.g., a medical examination). The experiment will compare a group trained to use CS-HH in these simulated encounters with a second, closely matched group, that is trained to use conventional verbal and nonverbal strategies to compensate for their spoken language deficits (the control group). Experimental and control groups will be compared on a total of five service encounters: three that subjects train for in therapist-led sessions, and two that they prepare for without therapist involvement (the generalization test). The prediction is that the experimental group will use the CS-HH to communicate more effectively both in the encounters they train for and in those they prepare themselves. A second study will use qualitative techniques (focus groups, semistructured interviews) to explore patients' assessment of their communicative competence in service- and other encounters, and their attitudes toward communication aids, both technological and conventional (e.g., picture books, gestures). It is predicted that after using the CS-HH in simulated service encounters, patients will view themselves as more effective communicators than they did at the start and will be positively disposed to using this AAC device in the future.

描述（由申请人提供）：基于 PC 的通信系统 (CS) 是为患有获得性失语症的成人开发的。它充当“处理假肢”，通过离线创建语音消息并最大限度地减少对快速检索和工作记忆的需求。作为 AAC 设备，CS 已被证明可以增强失语症患者在叙事任务中的流畅性和语法表达。作为一种治疗工具，它在家庭独立练习后改善了无辅助生产。该提案将扩展 CS 的功能，使用户能够将 CS 生成的适合特定情况的消息传输到手持计算机上，手持计算机可以在现场部署，以补充或提示现实世界、实时通信中的语言生成。其目的是创建一种 AAC 设备，不仅能够传输适合这些情况的信息，而且还允许用户展示他或她的智力能力，而这可能会因语言障碍而被掩盖。提出了一项实验来评估增强型系统（CS 加手持式：CS-HH）是否以及如何有利于失语症患者在预期模拟服务遭遇（例如医疗检查）时准备的消息通信。该实验将对在这些模拟遭遇中使用 CS-HH 进行训练的一组与第二个密切匹配的组进行比较，该组经过训练使用传统的言语和非言语策略来补偿他们的口语缺陷（对照组）。实验组和对照组将在总共五次服务遭遇中进行比较：其中三次是受试者在治疗师主导的课程中进行培训，两次是他们在没有治疗师参与的情况下进行准备（泛化测试）。预测实验组将使用 CS-HH 在他们训练的遭遇和他们自己准备的遭遇中更有效地沟通。第二项研究将使用定性技术（焦点小组、半结构化访谈）来探讨患者对其在服务和其他遭遇中的沟通能力的评估，以及他们对技术和传统沟通辅助工具（例如图画书、手势）的态度。据预测，在模拟服务体验中使用 CS-HH 后，患者将认为自己比开始时更有效的沟通者，并且将来会积极倾向于使用该 AAC 设备。
