一项实证研究进行了训练幼稚的受试者使用原型布尔逻辑为基础的信息检索系统的书目数据库。研究对象是很少或没有计算机经验的本科生。接受系统概念模型训练的受试者比接受程序指令训练的受试者表现得更好，但仅限于复杂的、解决问题的任务。在简单任务上的表现是一样的。与系统（基于随机过程模型）相互作用模式的差异显示出相似的结果。大多数受试者都能够清晰地描述系统的操作，但很少有人能够清晰地描述一个类似于培训中提供的卡片目录类比的模型。43名受试者中有11名无法达到最低限度的系统使用能力。不合格率在训练条件和性别之间是相等的；通过和不通过基准测试的人之间唯一的区别是学术专业和使用图书馆的频率。
An empirical study was performed to train naive subjects in the use of a prototype Boolean logic-based information retrieval system on a bibliographic database. Subjects were undergraduates with little or no prior computing experience. Subjects trained with a conceptual model of the system performed better than subjects trained with procedural instructions, but only on complex, problem-solving tasks. Performance was equal on simple tasks. Differences in patterns of interaction with the system (based on a stochastic process model) showed parallel results. Most subjects were able to articulate some description of the system's operation, but few articulated a model similar to the card catalog analogy provided in training. Eleven of 43 subjects were unable to achieve minimal competency in system use. The failure rate was equal between training conditions and genders; the only differences found between those passing and failing the benchmark test were academic major and in frequency of library use.
