Language Risk Taking scale and WTC on Social Media Questionnaire were employed to assess the participants’ degree of risk-taking propensity and WTC on social media. Then, Media Choice Questionnaire was adopted to examine the participants’ preference for social media of different immediacy and communication modes. ANOVA repeated measures was utilized to examine the differences in individuals’ WTC among different functions, and then one-way MANOVA was used to assess the impact of risk-taking propensity on WTC through social media. Finally, interviews were conducted with high- and low-WTC participants to learn more about what influenced their media choice behavior. The results can be summarized as follows. First, a significant effect of media function was found on the participants’ L2 WTC, and all of the pairwise comparisons were significant except that between Facebook Messenger and Facebook Messages, and that between Skype video call and Skype video messages. Both immediacy and communication mode showed significant effect on their WTC. Second, risk-taking propensity did not exert significant influence on one’s L2 WTC through the four functions provided by the two social media. Third, the interviewees’ comments on the influential factors of social media choice behavior were categorized into five main themes: media richness, authenticity of online communication, self-perceived proficiency, risk-taking propensity in a language, and others. At last, based on findings of the study, some pedagogical implications are offered for the English instructors, hoping to foster Taiwanese learners’ individual WTC when they communicate in English with others in authentic life.溝通意願社群媒體時效性溝通模式冒險傾向Willingness to Communicate (WTC)Social MediaImmediacyCommunication ModeRisk-taking Propensity
