【摘要】 本文以大学生中的强迫症状个体为研究对象,深入分析了大学生中的强迫症状个体的信息检索行为特点以及信息组织、信息表现方式对该类人群的影响,并对信息组织和表现方式提出相应的建议。通过文献调研和文本分析,本文在综合中外精神卫生领域对于强迫症状表征的描述基础上,结合当前部分研究中对于强迫症状个体的信息检索行为的研究成果,在利用ScL.90量表进行预实验后,深入分析了已有的强迫症状测量量表的不足,由此构建了大学生中强迫症状个体测量量表,并通过问卷预调查、被试访谈修正了该问卷。研究发现,与普通个体的信息检索行为相比,强迫症状个体：①会伴随一些相对无意义的刷新操作,而且比较频繁；②会立即关掉有关昆虫的图片或是一些表示污秽的图像；③倾向于收集一些与检索主题相关程度不高的内容；④更多的表现为点击固定的软件、网站时的一种程序化行为；⑤对需要输入的内容作反复核对；⑥在阅读时还会用鼠标点选其中的关键字词,而主标题与章节小标题,更是其关注的焦点；⑦容易发生检索目标偏移,使其很难回到原有的检索目标上,致使不能完成检索任务。另外,一些特定的信息组织、信息表现方式也对强迫症状个体有影响：强迫症状个体倾向于使用简洁的、没有浮动元素的页面,对标题与章节名相对较执着,对污秽、昆虫、细菌类页面的反感,对纯图片页面的关注度较小。在上述实证研究的基础上,本文进一步对信息组织、信息出了相应的建议：减少页面所承载的内容、明确页面内容标识、尽量减少页面浮动元素、将内容更多的以“图+文字”的形式表现、检索结果的呈现应“避繁就简”等。更多还原

【Abstract】 This paper chooses obsessive-compulsive symptoms college students as research object, and thoroughly analyzes the characteristics of obsessive-compulsive symptoms college students’ information retrieval behavior and the influence of information organization as well as information expression on these populations, then makes recommendations about information organization and information expression.On the basis of literature review and content analysis, the dissertation consolidates the description of compulsive symptoms in both foreign and domestic mental health fields.According to the study about obsessive-compulsive symptoms in information retrieval behaviors; the researcher conducts a pre-experiment of SCL-90 scale. After the experiment, the deficiencies of the existing obsessive-compulsive symptoms scale is analyzed and a college students obsessive-compulsive scale is constructed, then questionnaire and interview is implemented in order to revise this scale. On this basis, the author studies the information retrieval difference between obsessive-compulsive symptoms students and normal students,draw the following major conclusions, the obsessive-compulsive symptoms ones:①will refresh meaninglessly, and this operation is relatively frequent;②will turn the search results off immediately if it has pictures of insects or dirty things;③tend to collect and retrieve low relevance content;④use software and website are unconscious routine behavior;⑤need to cross check input in fear of errors;⑥will click the key words with mouse, especially the main chapter headings and subheadings in their reading;⑦will more likely to target offset and be difficult for them to refocus on their target, making it impossible to complete search tasks.In addition, some specific information organization and information expression are also affect obsessive-compulsive symptoms individuals:obsessive individuals tend to use simple, no floating element webpages, and they are more concerned with the title and chapter names, to the pages that include dirty, insects, bacteria pictures they often have aversion, and they do not care about pure image page. On the basis of empirical research, this dissertation further makes some recommendations to information organization and information expression:reduce the content per page;make identification of page content clear, minimize the number of floating elements,make the expression of information as "picture+words", the presentation of search results should be simple, etc.更多还原
