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

小行星9202253 这是一个为期三年的连续奖项的第一年，该奖项旨在调查计算机用户如何从使用入门系统适应使用更先进的系统。 这项研究不仅涉及到用户适应的问题，但也有一个计算机系统可以提供的中介作用。 该方法是基于比较的基本和先进的系统任务，在该地区的简要写作和计算机编程。 跨任务转移的影响也检查，以及任何明显的纵向影响的模式的使用和适应随着时间的推移，科目变得更加熟悉的系统。 同样的结构信息的图形表示的变化也被认为是在实验序列。 考虑的方法问题是直接检查受试者的“大声思考”对潜在行为扭曲和协议数据的完整性和一致性的影响。 目前的概念扩展到一个更一般的认知架构的基础上的认知模式和策略，适用于一些不同的智力任务，是本调查的目标，面向最终发展的计算机系统更一致的方式，用户认为。

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.
