In this article, the author examined the relationships of motivation and flow experience to academic procrastination in 262 Korean undergraduate students who completed a questionnaire on procrastination, flow, and motivation. The results indicated that high procrastination was associated with lack of self-determined motivation and low incidence of flow state. The results also indicated that, although amotivation and intrinsic motivation showed significant unique effects on procrastination, they

The present experiment investigated if and how other readers’ reactions to news on Internet portal sites affect individuals’ perceptions of public opinion, assessments of media influence, and their personal opinion. In so doing, others’ responses were shown as either individual comments or aggregate approval ratings of the article, and the individual’s need for cognition (NFC) was considered as a potential moderator of their relative effects. High NFC individuals relied more on the approval rati

Innovations in communication technology have changed the way news is produced and consumed. Various digital platforms, ranging from news websites to social media sites to personal blogs, have enabled news users to indicate how much they like the news they have read, to share it with others, and to leave comments. News users' mouse clicks are automatically recorded and aggregated by computational systems and made publicly visible (e.g., “Most Read Articles”). This essay reviews the ever-growing r

This study investigated if user-generated comments on Internet news sites affect readers' inferences about public opinion, and subsequently, their perceptions of media bias, and how ego-involvement moderates such effects. Supporting the notion that hostile media perception (HMP) stems from defensive processing, those who read others' comments discordant (vs. concordant) with their own opinion believed that the public was against their position and perceived the news report to be more hostile and

The present study investigated when and how the level of interactivity in politicians' Twitter communication affects the public's cognitive and affective reactions. In a Web-based experiment (n=264), participants viewed a high profile male politician's Twitter page, wherein he was either actively responding to his followers' questions (high interactivity) or mostly posting messages on his own (low interactivity). Exposure to the high-interactivity Twitter page induced a stronger sense of direct

The beneficial effects of stem cells in clinical applications to date have been modest, and studies have reported that poor engraftment might be an important reason. As a strategy to overcome such a hurdle, we developed the spheroid three dimensional (3D) bullet as a delivery method for human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) through the maintenance of cell-cell interactions without additional xenofactors, cytokines, or matrix. We made spheroid 3D-bullets from hUCB-

Two experiments investigated when and how politicians' Twitter communication affects the public's cognitive, affective, and behavioral reactions, focusing on the effects of message personalization. In Study 1, personalized (vs. depersonalized) messages significantly enhanced message recognition and recall, but they heightened perceived presence of and imagined intimacy with the candidate only among more affiliative individuals, while lowering the willingness to vote for him among less affiliativ

Two studies investigated (a) how public figures’ interaction with their followers on social network sites (SNS) affects individuals’ impressions about and attitudes toward them, and (b) how individuals’ interpersonal orientation moderates such effects, if any. In Study 1, participants viewed either a famous actor’s Twitter page or a news article merely relaying his Tweets. Exposure to the Twitter page (vs. news article) induced stronger feelings of actual conversation (i.e., social presence) amo

본 연구는 인터넷 뉴스 기사에 등록된 댓글이 기사에 대한 평가를 비롯, 해당 이슈에 대한 여론 및 기사의 사회적 영향력에 대한 지각에 차이를 가져오는가, 또 댓글이 어떠한 조건에서 뉴스 수용자의 의견에 영향을 주는가를 살펴보았다. 이를 위해 135명의 실험 참가자들에게 기사만 읽게 하거나(통제집단) 아니면 기사와 반대 논조를 보이는 댓글을 함께 읽도록 하였다(실험집단). 실험 결과, 사람들은 댓글을 통해 온라인 공간의 여론뿐 아니라 한국 사회의 일반적 여론도 추론하는 경향을 보였다. 또한 댓글에 노출된 집단은 기사만 읽은 집단에 비해 기사를 보다 부정적으로 평가했고, 나아가 기사가 여론, 특히 네티즌 여론에 미치는 영향력도 상대적으로 작다고 판단했다. 한편 댓글은 기사가 뉴스 수용자의 의견에 미치는 영향을 감소시키는 조절변인으로도 작용했는데, 이러한 효과는 평소 댓글에 대해 가지고 있는 선유 태도와 무관하게 나타났다. 종합하면, 본 연구는 ‘가정된 미디어 영향력의 효과(Gunther
