Websites, social media, mobile apps and indeed most internet platforms offer two distinct kinds of interactivity: one that involves interacting with the system, or what is commonly known as human-computer interaction (HCI), and another that involves interacting with other users, or computer-mediated communication (CMC). Are some people drawn toward one more than the other? And, is this indicative of one's social orientation? We decided to find out by examining whether extroverts and females are more likely to favor the latter type of interactivity, given their greater emphasis on relational aspects of communication. Through a between-subjects experiment with four conditions (Interactivity with HCI tools vs. CMC tools vs. HCI + CMC tools vs. Control), this research examined how extraversion and gender moderate the psychological effects of message interactivity on a movie news site. Results suggest that interactivity with CMC tools leads to a greater psychological perception of interactivity than interactivity with HCI tools. Moreover, extraversion positively predicts website attitudes for both interactivity types individually, yet it negatively predicts website attitudes when the website affords both together. The study also found a three-way interaction between interactivity, extraversion, and gender on perceived interactivity, revealing that extraversion helps males perceive more interactivity in HCI tools while it helps females perceive more interactivity in CMC tools. Theoretical implications for interactivity literature and practical implications for interface design are discussed.

网站、社交媒体、移动应用程序甚至大多数互联网平台都提供两种截然不同的交互方式：一种涉及与系统交互，或通常称为人机交互 (HCI)，另一种涉及与其他用户交互，或计算机中介通信 (CMC)。有些人是否比另一种更倾向于一种？而且，这是否表明了一个人的社会取向？我们决定通过检查外向者和女性是否更可能偏爱后一种交互方式来找出答案，因为他们更加强调交流的关系方面。通过具有四种条件的受试者间实验（与 HCI 工具的交互性 vs. CMC 工具 vs. HCI + CMC 工具 vs. Control），这项研究调查了外向性和性别如何调节电影新闻网站上信息交互的心理影响。结果表明，与 HCI 工具的交互相比，与 CMC 工具的交互导致对交互的心理感知更大。此外，外向性分别对两种交互类型的网站态度进行积极预测，但当网站同时提供两种交互类型时，它会消极预测网站态度。该研究还发现，交互性、外向性和性别之间在感知交互性方面存在三向交互作用，表明外向性有助于男性在 HCI 工具中感知更多交互性，同时帮助女性在 CMC 工具中感知更多交互性。讨论了交互性文献的理论意义和界面设计的实际意义。
