有「長輩圖」之稱的圖文影像，近年來透過Line廣為傳遞，成為熟齡3C世代的新文化。本研究根據圖文內容將長輩圖分為四類型，結合社會情緒選擇理論以及社群使用與滿足觀點，以七種因素探討不同類型的長輩圖分享程度，並加入未來時間觀點為調節變數。針對538份50歲以上受測者填寫的問卷進行迴歸分析，結果發現社交互動、放鬆娛樂及消磨時間，與熟齡族群的長輩圖分享程度具正向關係，在各類型長輩圖中，社交互動為分享問候及勸世名言類型長輩圖的主因，放鬆娛樂及表述資訊分享則影響趣味及新聞資訊類型長輩圖，進一步探索未來時間觀點則發現，當熟齡族群的未來時間觀點越偏向限制，情感表達對問候與趣味類型圖片分享程度的效果越強。

The development of mobile communication applications (apps) has encouraged greater senior adoption and use. A newly emerged image type that is often embedded with texts and slogans become popular among mature aged Line users. Unlike emoticons or stickers used in mediated environment to depict certain emotions or gestures, these images, often called “info-pictures,” are not expressive in nature. The goal of this study was to explore factors that may influence sharing info-pictures within the context of uses and gratifications and socioemotional selectivity perspectives. A survey of 538 Line users aged 50 years and older was conducted, and the results showed that social interaction, relaxing entertainment, and habitual pass time positively related to info-pictures sharing intensity. Social interaction particularly affected greeting and motto types of info-pictures sharing while relaxing entertainment and expressive information sharing were associated with pleasure and information types of info-pictures sharing, respectively. The moderating effect of future time perspective was further examined. Theoretical and practical implications are also discussed.
