COMMUNICATION DEVICE EFFECT--CONVERSATIONAL PERFORMANCE

该项目试图解决技术之间的差距 增强通信设备（ACD）的开发和我们的 了解所需的认知和语言处理 他们的用途。 为了实现这一目标，我建议研究以下因素的影响： 关于用户及其合作伙伴沟通方式的 ACD。 研究 旨在确定该类型对通信的影响 所使用的设备以及永久性、冗余性和 由创建的消息的时间/空间特征 设备。 将研究这些与设备相关的变量 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) 接收者和观察者对能力的判断 ACD 用户的数量。 根据这些研究获得的数据， 将开发增强通信模型 评估其预测对话表现的效果 实验和自然主义背景。 第 1-3 年将涉及 在受控实验环境中研究二元沟通。 无残障成年人将作为受试者减少受试者 残障用户之间存在差异。 多年来的研究 3和4将扩展实验工作以包括单受试者 残障 ACD 用户的实验和研究 自然主义的设置。 最终，将开发出 ACD 原型 使用研究结果。 总体目标是发展 一套用于生产的社会沟通规范 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.
