The present study examined the relationship between two distinct subfactors of spatial ability and performance in an information search task modeled on browsing the Web.
Previous studies have found relationships between various measures of spatial ability and performance in a wide variety of computer-based tasks.
In the search task 101 participants (18-29 years of age) searched for the answer to a question by navigating the system. They completed the experimental task as well as a battery of cognitive ability measures that included two different measures of spatial ability.
The results indicate that spatial orientation ability was related to performance with tasks that were high in their navigational requirement (engendered by the use of a novel aid), whereas spatial visualization was unrelated to performance in any task condition.
A closer inspection of the cognitive requirements of a task may reveal what interventions could be most useful when designing computer systems or developing training programs.
Given the unique differences between the different spatial abilities, the current results suggest the design of navigational aids that place less demand on spatial orientation ability.
本研究考察了空间能力的两个不同子因素与基于网络浏览建模的信息搜索任务表现之间的关系。
先前的研究发现，各种空间能力测量指标与多种基于计算机的任务表现之间存在关联。
在搜索任务中，101名参与者（年龄在18至29岁之间）通过在系统中导航来寻找问题的答案。他们完成了实验任务以及一系列认知能力测量，其中包括两种不同的空间能力测量。
结果表明，空间定向能力与导航要求高的任务（由使用新型辅助工具引发）的表现相关，而空间视觉化与任何任务条件下的表现均无关。
对任务认知要求的更深入考察可能会揭示在设计计算机系统或开发培训项目时哪些干预措施可能最有用。
鉴于不同空间能力之间存在独特差异，当前结果表明应设计对空间定向能力要求较低的导航辅助工具。
