研究了分层文件系统的用户之间的个体差异。结果表明，词汇和空间可视化的心理测量测试是任务绩效的最佳预测指标，占数据差异的45％。发现空间预测变量是最具影响力的。这是一个事实，这是一个很大程度上说明的，即平均而言，空间能力低的受试者执行任务是具有高空间能力的受试者的两倍。令人惊讶的是，仅体验并不能预测任务绩效。比较高和低空间能力的受试者之间命令使用频率的比较表明，在层次结构结构中，空间能力较低的人正在丢失。这些数据对重新设计软件接口具有影响，以容纳具有低空间能力的人。
Individual differences among users of a hierarchical file system were investigated. Results indicate that psychometric tests of vocabulary and spatial visualization are the best predictors of task performance, accounting for 45% of the variance in the data. The spatial predictor was found to be the most influential. This was dramatically illustrated by the fact that, on the average, subjects with low spatial ability took twice as long to perform the task as those with high spatial ability. Surprisingly, experience alone does not predict task performance. A comparison of the frequency of command usage between subjects with high and low spatial ability revealed that those with low spatial ability were getting lost in the hierarchical file structure. These data have implications for redesigning the software interface so as to accommodate people with low spatial ability.
