The emergence of artificial intelligence has boosted the development and utilization of chatbots that can satisfy both users' task-oriented needs, such as information search for purchase, and their social needs, such as self-disclosure for rapport-building. While much research has focused on its usage in the commercial context, little effort has been paid to examine social chatbots for psychotherapy, where facilitating relationship formation is crucial in chatbot design. Inspired by prevalent chatbot applications and drawing on the literature on visual cues and self-disclosure, this paper aims to 1) explore the effects of different presentations of social chatbot avatars (text, profile, and background) on users' self-disclosure, along with the mediating role of self-awareness, and 2) understand the moderating role of chatbot gaze directions (direct gaze and averted gaze). The proposed studies will theoretically contribute to literature regarding human-robot interaction. Research findings will also provide substantial practical implications for chatbot design.
