COMMUNICATION DEVICE EFFECT--CONVERSATIONAL PERFORMANCE

该项目试图解决技术和技术之间的差距 增强通信设备(ACDs)的发展及OUR 理解所需的认知和语言处理 它们的用途。为了实现这一目标，我建议研究 用户及其合作伙伴交流方式上的ACD。这项研究 旨在确定该类型对通信的影响 以及永久性、冗余性和 创建的消息的时间/空间特征 设备。这些与设备相关的变量将被研究 对(1)用户参考主题的能力和 事件；(2)接收者理解信息的能力；(3) 用户和接收者管理交互的能力，以及 (4)接受者和观察者对能力的判断 ACD用户的比例。根据这些研究获得的数据， 将开发一种增强通信的模式，并 评估它在以下方面预测会话性能的好坏 实验和自然主义的背景。第一年至第三年将涉及 在受控实验环境中研究并元通信。 非残障成人将作为减少主题的对象 在残障用户中发现的可变性。多年来的研究 3和4将把实验工作扩展到包括单一主体 残障ACD使用者的实验和临床研究 自然主义的背景。最后，将开发一个ACD原型 利用这些研究的结果。总体目标是发展 一套社会沟通规范，用于生产 新一代适合社交的沟通方式 技术。

This project attempts to address the gap between the technological development of Augmentative Communication Devices (ACDs) and our understanding of the cognitive and linguistic processing needed for their use. Towards this goal, I propose to study the influence of ACDs on the way users and their partners communicate. The research is aimed at determining the effects on communication of the type of device used as well as the permanancy, redundancy, and temporal/spatial characteristics of the message created by the device. These device related variables will be studied for their influence on (1) the user's ability to refer to subjects and events; (2) the receiver's ability to comprehend the message; (3) the user's and receiver's ability to manage the interaction, and (4) the judgments receivers and observers make about the competence of the ACD users. Based on the data obtained from these studies, a model of augmentative communication will be developed and evaluated for how well it predicts conversational performance in experimental and naturalistic contexts. Years 1-3 will involve the study of dyadic communication in a controlled experimental context. Nonhandicapped adults will serve as subjects to reduce the subject variability found among handicapped users. Research during years 3 and 4 will extend the experimental work to include single-subject studies of handicapped ACD users in both experimental and naturalistic settings. Finally, a prototype ACD will be developed using the findings of the studies. The overall aim is to develop a set of social communication specifications for the production of a new generation of socially appropriate communication technologies.
