Afundamental study of psychological and behavioral function of elderly people while using IT devices

本研究中，六个研究小组从感知、认知和心理功能几个方面研究了使用IT设备的衰老效应。(1)数据库组通过整合其他组的成果，对IT设备的设计提出了适当的指导。(2)知觉注意组通过行为数据和问卷调查两种方法考察了年龄对注意抑制功能的影响，并指出了各方法在老年人中的结果差异。(3)心理模型组在使用IT设备时对心理模型的构建水平存在老化效应。(4)错误组使用汉字选择任务考察了老年人的错误重复现象，并考察了任务切换的特征。(5)电机输出组根据双任务性能结果，提出了车辆接口的合理配置。(6)社会心理小组采用访谈法将老年人使用IT设备的老化特征分为五种模式。六个研究小组的这些发现揭示了年龄和脑力负荷对IT设备使用的影响。

In this project, six groups have investigated the aging effects on using IT devices from several aspects of the perceptual, cognitive, and psychological function. (1) Database group proposed an appropriate guidance for designs of IT devices by integrating the results of other groups. (2) Perception and attention group examined the aging effect on the inhibition function of attention by both the behavioral data and the questionnaires and indicated the discrepancy of the result of each method in aged people. (3) Mental model group indicated the aging effect on the construction level of a mental model while using IT devices. (4) Error group used kanji selection task to examine an error repetition phenomenon and investigated the characteristics of the task switching for elderly people. (5) Motor-output group proposed the proper configuration of the interfaces in vehicles based on the result of dual task performance. (6) social-psychological group revealed the characteristics of aging when aged people used IT devices broken into five patterns by using interview method.These findings by six research groups revealed the influence of aging and mental workload on the use of IT devices.
