限時動態以不同於傳統動態消息的媒體形式抓住了年輕人的目光，限時動態主打原汁原味的內容、隨拍隨傳，以佔滿螢幕直式的沉浸呈現方式輪播所有的限時動態，只要閒時時限時動態往往是年輕人第一個開啟的app，透過限時動態可以快速了解朋友當下的生活，或是自己也可以立即分享當下的心情。然而像限時動態這樣的暫時性社群媒體，相關研究還不是相當豐富，本研究以心流理論探討使用者對於限時動態的黏著程度，認為正是限時動態的媒體特性增強了心流體驗的前置因素，進而讓心流體驗更強烈。此外，本研究採用了問卷與實驗測量的複合方式，受測者會在實驗研究室中填寫電腦問卷，在其中一個階段進行觀看限時動態的腦波測量，接著再繼續完成問卷。本研究將以專注與放鬆程度作為干擾變數，探討其對心流與黏著度之間影響性的干擾效果。研究結果顯示，限時動態的媒體特性(時效性、稀少性、故事性、互動性)，加強了心流體驗的前置因素(技能與控制感、挑戰與激勵感、時間扭曲與臨場感)，心流體驗對黏著度的影響亦達顯著，放鬆程度則具有負向干擾效果，而技能與控制感對心流的影響、專注程度的干擾效果、及時效性對時間扭曲與臨場感的影響性則未達顯著。

Stories capture the attention of young people in a media form different from traditional posts. Stories focus on original content and instant sharing , playing all Stories in an immersive presentation that fills the screen. Stories is often the first app that young people visit, through Stories, you can quickly understand the current moment of your friends, or you can immediately share your current mood. However, for ephemeral social media like Stories, the relevant research is not that enough. This study uses the flow theory to explore the user's stickiness to Stories. It is believed that it is the media characteristics of Stories that enhances the flow experience. In this study, the degree of attention and meditation will be used as moderator variables to explore the effect of moderation on the flow and stickiness. The results of the study show that Stories’ characteristics (timeliness, scarcity, characteristic of storytelling, and interactivity) strengthen the antecedents of the flow experience (skills and control, challenge and motivation, time distortion and presence). The influence of flow experience on stickiness is also significant, and the degree of meditation has a negative moderation effect, while the influence of skill and control on flow, the moderation effect of concentration, and the effect of timeliness on time distortion and presence Is not significant.
