超文本为用户提供了一种简单、灵活的方式在电子信息系统中导航，但存在在相互关联的信息网络中迷路的潜在风险。对使用基于商业超文本的帮助系统的信息检索进行了研究。结果发现，主要的搜索策略是“浏览”(特征是扫描目录和在主题中分页)，而不是使用索引(“分析性搜索”)。尽管受试者没有迷失，但通过标准化测试衡量，空间可视化能力较好的个体在检索信息时速度更快，而且比空间可视化能力较差的个体更少返回信息层次的顶端。这些结果支持了之前的研究，这些研究发现用户强烈倾向于在超文本系统中浏览，并将这些发现扩展到新的领域(帮助)、不同类型的用户界面和不同的信息体系结构。此外，实验结果还证明了空间可视化能力对于层次化超文本系统中高效导航和信息检索的重要性。
Hypertext offers users a simple, flexible way to navigate through electronic information systems but at the potential risk of becoming lost in the network of interconnected pieces of information. A study was conducted on information retrieval using a commercial hypertext based help system. It was found that the predominant search strategy was “browsing” (characterized by scanning tables of contents and paging through topics), rather than employing the indexes (“analytical search”). Although subjects did not become lost, individuals with better spatial visualization ability, as measured by a standardized test, were faster at retrieving information and returned to the top of the information hierarchy less often than those with poorer spatial visualization ability. These results support previous studies that have found a strong preference by users to browse in hypertext systems and extend those findings to a new domain (help), a different type of user interface, and a different information architecture. In addition, the results demonstrate the importance of spatial visualization ability for efficient navigation and information retrieval in a hierarchical hypertext system.
