Cognitive load is a significant challenge to users for being deliberative. Interface design has been used to mitigate this cognitive state. This paper surveys literature on the anchoring effect, partitioning effect and point-of-choice effect, based on which we propose three interface nudges, namely, the word-count anchor, partitioning text fields, and reply choice prompt. We then conducted a 2*2*2 factorial experiment with 80 participants (10 for each condition), testing how these nudges affect deliberativeness. The results showed a significant positive impact of the word-count anchor. There was also a significant positive impact of the partitioning text fields on the word count of response. The reply choice prompt showed a surprisingly negative affect on the quantity of response, hinting at the possibility that the reply choice prompt induces a fear of evaluation, which could in turn dampen the willingness to reply.

促进协商：界面特征如何影响在线话语

认知负荷对用户进行深思熟虑是一个重大挑战。界面设计已被用于缓解这种认知状态。本文对锚定效应、分区效应和选择点效应的文献进行了调查，在此基础上我们提出了三种界面微调，即字数锚点、分区文本字段和回复选择提示。然后，我们对 80 名参与者（每个条件 10 名）进行了 2*2*2 的析因实验，测试这些轻推如何影响审慎性。结果表明，字数锚点具有显着的积极影响。划分文本字段对响应的字数也有显着的积极影响。回复选择提示对回复数量显示出惊人的负面影响，
