This study is the third in a series of studies that have concentrated on utterance-based systems--which allow the relatively quick selection of full sentences--and investigated trade-offs faced by users of such systems when there is a pragmatic mismatch between the prestored sentence and the current discourse context. While the previous studies focused on trade-offs between speed of message delivery and either relevance or informativeness, this study investigated the effects of trade-offs between speed of message delivery and brevity on public attitudes. Participating were 96 sales clerks who viewed scripted, videotaped trade-off message conditions in the context of a bookstore interaction and completed a questionnaire designed to assess their attitudes toward customers who used utterance-based systems and his or her communication. Significantly higher mean ratings were found for the trade-off condition involving the quickly delivered message with repetition when compared to each of the slowly delivered, non-repetitive message conditions (i.e., with and without a preceding conversational floorholder). Implications regarding the model of conversational trade-off choices and its technological applications are discussed.
本研究是一系列专注于基于话语的系统（该系统允许相对快速地选择完整句子）的研究中的第三项，研究了此类系统的用户在预存储句子与当前话语语境之间存在语用不匹配时所面临的权衡。虽然之前的研究聚焦于信息传递速度与相关性或信息量之间的权衡，但本研究调查了信息传递速度与简洁性之间的权衡对公众态度的影响。参与研究的是96名店员，他们在书店互动的情境中观看了预先写好脚本并录制好的权衡信息条件，并完成了一份旨在评估他们对使用基于话语系统的顾客及其沟通方式的态度的问卷。与每个缓慢传递、无重复的信息条件（即有和没有前面的会话开场者）相比，发现涉及快速传递且有重复信息的权衡条件的平均评分显著更高。文中讨论了关于会话权衡选择模型及其技术应用的相关问题。
