虽然设计的通用性通常已通过分析人与人工制品的相互作用得到验证，但与年轻人相比，老年人在使用多种类型的IT设备时经常表现出困难。我们假设年龄组的差异是由于老年人的学习效率低下，他们受到认知功能下降的影响，包括情景记忆。为了验证这一假设并探索补偿这种学习效率低下的方法，实验1采用四种不同的设计来考察学习使用一种IT设备（一种饮食支持系统，WELLNAVI）的情况。结果表明，与年轻人相比，老年人在学习使用设备方面存在困难。然而，四种设计之间的比较显示，消除一些决策要求促进了老年人的学习，并且在印刷书籍中呈现信息，而不是通过计算机，也促进了学习。实验2的结果表明，以书本形式呈现的任务结构信息对学习是有效的。jpr_440 227.. 243
Although design universalities have generally been validated through analy- ses of human-artifact interactions, older adults frequently exhibit difficulties in using many types of IT-based equipment compared with younger adults. We hypothesize that the age-group difference is due to inefficient learning by the older adults, who are affected by declines in their cognitive functions, including episodic memory. In pur- suing this hypothesis and exploring ways to compensate for such learning ineffi- ciency, Experiment 1 was conducted to examine learning to use a piece of IT equipment (a diet-support system, WELLNAVI) with four different designs. The results indicated that older adults had difficulties in learning to use the equipment compared with younger adults. However, comparisons between the four designs revealed that eliminating some decision requirements facilitated learning in the older adults, and that presenting information in a printed book, rather than via computer, also promoted learning. The results of Experiment 2, investigating why the printed format facilitated learning in the older adults, suggest that the task-structure informa- tion physically represented in the book format is effective for learning. jpr_440 227..243
