ABSTRACT Artificially intelligent (AI) agents increasingly occupy roles once served by humans in computer-mediated communication (CMC). Technological affordances like emoji give interactants (humans or bots) the ability to partially overcome the limited nonverbal information in CMC. However, despite the growth of chatbots as conversational partners, few CMC and human-machine communication (HMC) studies have explored how bots’ use of emoji impact perceptions of communicator quality. This study examined the relationship between emoji use and observers’ impressions of interpersonal attractiveness, CMC competence, and source credibility; and whether impressions formed of human versus chatbot message sources were different. Results demonstrated that participants rated emoji-using chatbot message sources similarly to human message sources, and both humans and bots are significantly more socially attractive, CMC competent, and credible when compared to verbal-only message senders. Results are discussed with respect to the CASA paradigm and the human-to-human interaction script framework.

机器人和微笑：聊天机器人和人类在计算机媒介通信中使用表情符号的人际印象

摘要 人工智能 (AI) 代理在计算机中介通信 (CMC) 中越来越多地占据人类曾经服务过的角色。表情符号等技术可供性使交互者（人类或机器人）能够部分克服 CMC 中有限的非语言信息。然而，尽管聊天机器人作为对话伙伴的数量不断增加，但很少有 CMC 和人机通信 (HMC) 研究探索机器人使用表情符号如何影响对沟通者质量的看法。本研究检验了表情符号的使用与观察者对人际吸引力、CMC 能力和来源可信度的印象之间的关系；以及由人类和聊天机器人消息来源形成的印象是否不同。结果表明，参与者对使用表情符号的聊天机器人消息源的评分与人类消息源类似，与仅使用语言的消息发送者相比，人和机器人都更具社交吸引力、CMC 能力和可信度。结果将根据 CASA 范式和人与人交互脚本框架进行讨论。
