With support from the National Science Foundation, the University of Chicago Committee on Cognition and Communication will purchase: a video digitizing PowerMac 9500/132, 4 Silicon Graphics Indigo2 ZX workstations, 3 DigitalLinear Tape 20 GB backup systems and a Young Minds CD-ROM recorder. This equipment will permit the group to digitize multimedia recordings of communication situations and to code and analyze various properties of each digitized recording. It will also establish the groundwork for the creation of a large multimedia database of communication situations. The database will contain coded and measured information about each communicative situation. It will include classifications of gestures made qualitatively by researchers acoustical measurements of speech, and measurements of gesture movement using image processing tools. The goal of this research is to investigate the cognitive mechanisms that mediate processing in conversational interaction, and utterance production and comprehension. To fully understand verbal communication, language use must be studied in natural communicative contexts such as conversations, arguments, narratives, recall of emotional events and parent-child interaction. Natural communicative contexts contain rich sources of information that govern the dynamics of language processing in ways that cannot be observed in standard laboratory situations. The analysis system which the Chicago group will employ, will allow studies of this type to be conducted. The instrumentation system will also be used in teaching situations and be available to graduate and undergraduate students.

在国家科学基金会的支持下，芝加哥大学认知与交流委员会将购买：一台视频数字化PowerMac 9500/132、4台Silicon Graphics Indigo 2 ZX工作站、3台DigitalLinear Tape 20 GB备份系统和一台Young Minds CD-ROM刻录机。该设备将使小组能够对通信情况的多媒体录音进行解码，并对每一数字化录音的各种特性进行编码和分析。它还将为建立一个关于通信情况的大型多媒体数据库奠定基础。该数据库将包含有关每种交流情况的编码和测量信息。它将包括由研究人员对语音的声学测量进行定性的手势分类，以及使用图像处理工具对手势运动进行测量。 本研究的目的是探讨会话互动中的认知加工机制，以及话语的产生和理解。为了充分理解言语交际，语言使用必须在自然的交际环境中进行研究，如对话，争论，叙述，回忆情感事件和亲子互动。自然交际语境包含丰富的信息源，这些信息源以标准实验室环境中无法观察到的方式支配着语言处理的动态。芝加哥小组将采用的分析系统将允许进行这类研究。该仪器系统也将用于教学情况，并提供给研究生和本科生。
