Adapting to Advanced Computer Systems: An Experimental Study of Computer-Mediated Cognition

9202253 Smith这是一个为期三年的持续奖项的第一年，该奖项旨在调查计算机用户如何从入门系统的使用适应到更高级系统的使用。本研究不仅涉及与用户适应有关的问题，而且还涉及计算机系统可以提供的中介效应。该方法是基于说明性写作和计算机编程领域的基本和高级系统任务的比较。还检查了跨任务转移效应，以及随着时间的推移，随着受试者对系统更加熟悉，在使用模式和适应方面的任何明显的纵向效应。在同一结构信息的图形表示的变化也被考虑在实验序列。考虑的一个方法学问题是直接检查受试者的“大声思考”对潜在行为扭曲的影响以及协议数据的完整性和一致性。将当前概念扩展到基于认知模式和策略的更一般的认知架构，适用于许多不同的智力任务，是本研究的目标，旨在最终开发出与用户思维方式更一致的计算机系统。

9202253 Smith This is the first year of a three-year continuing award to investigate how computer users adapt from the use of introductory systems to the use of more advanced systems. This study involves not only the issues related to user adaptation but also to the mediating effects that a computer system can provide. The methodology is based on comparisons of basic and advanced system tasks in the areas of expository writing and of computer programming. The cross-task transfer effects are also examined, as well as any noticeable longitudinal effects in patterns of use and adaption over time as subjects become more familiar with the systems. Variations in the graphical representations of the same structural information are also considered in the sequence of experiments. A methodological issue considered is the direct examination of the effects of the subject's "thinking-aloud" on potential behavioral distortions and completeness and consistency of the protocol data. The extension of current concepts to a more general cognitive architecture based on cognitive modes and strategies, applicable to a number of different intellectual tasks, is a goal of this investigation oriented towards the eventual development of computer systems more consistent with the manner in which users think.
