本文讨论了Card、Moran和纽韦尔（1983）的菜单级模型在软件中的应用中的一个关键问题，在该模型中，用户通过一个层次菜单系统来指定一个命令。例如，要在Lotus 1-2-3®中插入一行，用户可以进行三个菜单选择：W表示工作表，I表示插入，R表示行。在大脑层次模型中，假设在每个命令之前都有一个耗时的心理操作。在层次菜单系统中应用程序级模型的问题是，在前面的例子中，WIR是否构成三个命令的执行，因此需要三个心理操作，或者WIR是否作为一个单一的命令，只需要一个心理操作。数据是从四个非常有经验的Lotus 1-2-3用户那里收集的，因为他们正在进行日常工作。强有力的证据表明，只有一个心理操作参与选择从一个层次菜单系统。我们假设我们的结果与其他人的数据不一致是因为我们的受试者更有经验。我们的研究结果的菜单设计的影响进行了讨论。
This article addresses a key question in the application of Card, Moran, and Newell's (1983) keystroke-level model to software in which users specify a command by working through a system of hierarchical menus. For example, to insert a row in Lotus 1-2-3®, the user makes three menu choices: W for worksheet, I for insert, and R for row. In the keystroke-level model, it is assumed that a time-consuming mental operation precedes each command. The question in the application of the keystroke-level model to hierarchical menu systems is whether the keystrokes WIR in the previous example constitute the execution of three commands and thus require three mental operations or whether WIR acts as a single command and requires only one mental operation. Data were collected from four highly experienced Lotus 1-2-3 users as they went about their day-to-day work. Strong evidence that only one mental operation is involved in choosing from a hierarchical menu system was obtained. We hypothesize that the discrepancy of our results from the data of others is due to the fact that our subjects were more experienced. The implications of our findings for the design of menus is discussed.
