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 理解所需的认知和语言处理， 他们的使用。 为了实现这一目标，我建议研究 关于用户及其合作伙伴沟通方式的ACD。 研究 目的是确定对通信的影响类型 所用设备的永久性、冗余性和 创建的消息的时间/空间特征 设备. 将研究这些器械相关变量的 对（1）用户提及主题的能力的影响， （2）接受者理解信息的能力;（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。 根据从这些研究中获得的数据， 将开发一种增强通信模式， 评估它预测会话表现的能力， 实验性和自然主义的背景。 第1-3年将涉及 在受控实验环境中进行的二元沟通研究。 非残疾成年人将作为受试者， 残疾人用户之间的差异。 多年研究 3和4将扩大实验工作，包括单一主题 在实验性和非实验性研究中， 自然主义的设置。 最后，将开发原型ACD 利用这些研究的结果。 总体目标是发展 一套社会沟通规范， 新一代的社会适当的沟通 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.
