大众传媒时代，人们的互动空间由真实世界向虚拟世界迁移，社会中人们的呈现行为及社会互动突破既有格局，展现出多元化的特点，塑造一个个鲜活的社会形象。但社会中的残障群体大多被媒体塑造成单一的刻板形象，话语传播权利并没有从媒体延伸到个体本身。新型媒介形式的出现不仅是残障群体融入社会的途径和手段，更是他们开始自我表达的契机。

视频博客（VLOG）作为移动互联网时代推出的新兴媒介形式，重塑社交环境，因而影响着人们的呈现行为及动态化的社会互动。约书亚·梅罗维茨的“媒介情境理论”将新型媒介形式与受众社会互动行为相勾连，为研究提供了理论支撑。因而本研究以学者梅罗维茨的媒介情境论为研究框架，遵循“媒介—场景—行为—社会”的路径，分析残障群体视频博客（VLOG）文本中的前前台、中区、深后台行为展现，并尝试探讨残障群体视频博客（VLOG）广泛传播后所带来的社会互动变化。本文在绪论部分对媒介情境理论及残障群体相关文献进行梳理，阐明研究背景与意义。

第一章主要论述B站残障群体视频博客（VLOG）的发展现状，首先，具体分析了B站视频博客（VLOG）的发展历程和兴起轨迹。其次，针对B站场景的特性进行研究，其所具有获取准入门槛低、独特的弹幕文化和丰富的媒介讯息的独特属性，吸引了不同群体不断加入，尤其是残障群体等社会边缘群体也可以相对容易的融入其中。最后，本章的第二节从残障生活的故事阐述、公开呈现的残缺身体、第一视角的写实风格、突出情感的细节表达四个维度细致分析了残障群体在B站视频博客（VLOG）中的具体呈现内容。

第二章结合残障群体的媒介行为特征，探析该群体在视频博客（VLOG）中的呈现动因及呈现方式，试图深入了解残障群体在B站视频博客（VLOG）中的呈现行为。具体而言，这一部分笔者主要根据梅罗维茨的媒介情境理论并结合欧文·戈夫曼拟剧理论的前台、中区以及后台等概念对残障群体在B站视频博客（VLOG）中的呈现行为进行分析，研究发现残障群体主要通过前台的控制、中区的管理和后台的维持多个层面来呈现其在视频博客（VLOG）中的具体形象和共有的行为倾向。并且从四个维度探讨残障群体在B站视频博客（VLOG）中的呈现动因，即记录生活的呈现需要、满足自我的心理诉求、他者认同的意向投射、圈层群体的聚合推动。

第三章主要针对残障群体在B站视频博客（VLOG）中的社会互动进行分析，以深度访谈法为主，结合梅罗维茨的媒介情境论研究框架，从社会情境、社会角色、社会行为三个方面，具体论述视频博客（VLOG）情境中，残障群体的社会互动行为及其行为模式产生的影响。具体而言，其一社会情境方面，笔者从情境的融合、情境的延伸、情境的压缩三个面向具体探究残障群体视频博客（VLOG）是如何拓展社会情境的多元边界。其二，社会角色方面，笔者从残障群体的群体角色塑造、残障群体的权威角色重构和残障群体的社会角色转换三个层面分别探讨了残障群体社会角色身份的多重定义。其三，社会互动行为方面，笔者则从公共情境下的双向互动行为、群体身份下的组织互动行为、消解污名化的匿名互动行为以及边缘到中心的话语互动行为四个层面，进一步探讨了残障群体的社会互动行为，进而为研究视频博客（VLOG）新场景对残障群体行为的影响提供参考方向，期待能够为今后的相关研究提供一个新的视角。

In the age of mass media, people's interaction space is transferred from the real world to the virtual world. People's presentation behavior and social interaction in the society break through the existing pattern, showing the characteristics of diversification, and shaping a fresh social image. However, most of the disabled groups in society are shaped into a single stereotyped image by the media, and the right of discourse communication does not extend from the media to the individuals themselves. The emergence of new media forms is not only a way and means for disabled groups to integrate into society, but also an opportunity for them to start expressing themselves.

As a new form of media launched in the era of mobile Internet, video blog reshapes social environment, thus affecting people's presentation behavior and dynamic social interaction. Joshua Merowitz's "media situation theory" connects new media forms with audience's social interaction behavior, which provides theoretical support for the research. Therefore, this study takes the media situation theory of scholar Merowitz as the research framework, follows the path of "media-scene-behavior-society", analyzes the behavior display of front stage, middle area and deep background in VLOG texts of disabled groups, and attempts to explore the changes in social interaction brought by the widespread dissemination of VLOG texts of disabled groups. In the introduction part of this paper, media situation theory and related literature of the disabled group were sorted out to clarify the research background and significance.

The first chapter mainly discusses the development status of VLOG of disabled group in Station B. Firstly, it analyzes the development history and rising track of VLOG of Station B in detail. Secondly, the characteristics of the scene of Station B are studied. Its unique attributes of low access threshold, unique bullet screen culture and rich media information attract different groups to join the scene, especially the marginalized groups such as the disabled group, which can be integrated into the scene relatively easily. Finally, the second section of this chapter makes a detailed analysis of the specific content presented by the disabled in the video blog of  B station from four dimensions: the story exposition of the life of the disabled, the public presentation of the disabled body, the realistic style of the first perspective, and the detailed expression of the emotion.

In the second chapter, based on the characteristics of the media behavior of the disabled group, the motivation and way of presentation of the disabled group in the video blog are analyzed, trying to have an in-depth understanding of the presentation behavior of the disabled group in the video blog of B station. Specifically, in this part, the author mainly analyzes the presentation behavior of the disabled group in the B station VLOG based on the media situation theory of Merowitz and the concepts of foreground, center and background of Erwin Goffman's dramatics theory. It is found that the disabled group presents their specific image and common behavior tendency in VLOG through the control of foreground, the management of central area and the maintenance of background. In addition, the motivation for the presentation of disabled groups in B site VLOG is discussed from four dimensions, namely, the presentation needs of recording life, the psychological demands of satisfying oneself, the projection of the intention of others' identification, and the promotion of circle group convergence.

The third chapter mainly analyzes the social interaction of the disabled group in the VLOG of B station. Based on the in-depth interview method, combined with the research framework of Merowitz's media context theory, it specifically discusses the VLOG situation from the three aspects of social context, social role and social behavior. The influence of social interaction behavior and behavior pattern of disabled groups. Specifically speaking, in terms of social context, the author explores how vlogs of disabled groups expand the multiple boundaries of social context from three aspects: context integration, context extension and context compression. Secondly, in terms of social roles, the author discusses the multiple definitions of social role identity of disabled groups from three aspects: group role shaping, authority role reconstruction and social role transformation of disabled groups. Third, in terms of social interaction, the author further discusses the social interaction behavior of disabled groups from four aspects: two-way interaction in public context, organizational interaction in group identity, anonymous interaction to remove stigma, and discourse interaction from the edge to the center. Thus, it provides a reference direction for the study of the influence of new VLOG scenarios on the behavior of disabled groups, and is expected to provide a new perspective for future related research.
