本文介绍了一项自行开发的预测感觉运动任务学习时间的方法的有效性研究，该方法最初是为年轻人（AG I 年龄组）和 52 岁至 67 岁之间的人（AG II 年龄组）开发的。为此，我们对 60 名参与者进行了一项按年龄区分的样本进行实验室研究。参与者的任务是在三个任务描述之一的帮助下重复组装化油器，这三个任务描述的格式有所不同（文本、基于文本和图形、动画）。测量执行时间和组装错误的数量来评估人类的表现。此外，在每次试验中测量任务描述的累积观看时间，以分析参与者对任务描述的使用情况。对年龄组和任务描述格式的数据分析表明效果显着（α =0.05）。因此，获得文本任务描述支持的参与者比使用动画任务描述的参与者取得了更大的绩效提升。就年龄组而言，AG I 的参与者比 AG II 的参与者表现出更好的表现和更少的观察时间。此外，还进行了非线性曲线拟合并计算了均方根误差，以考察预测方法的准确性。结果表明，该预测方法对于老年人来说不太准确。
This paper presents a study into the validity of a self-developed method to predict the learning time of sensorimotor tasks that was originally developed for young adults (age group AG I) for persons aged between 52 and 67 (age group AG II). For this purpose, a laboratory study was conducted with an age-differentiated sample of 60 participants. The participants’ task was to repeatedly assemble a carburetor with the help of one of three task descriptions, which differed in regard to format (textual, text- & figure-based, animated). Execution times and numbers of assembly errors were measured to evaluate human performance. Additionally, the cumulative viewing time of the task description was measured in each trial to analyze participants’ usage of the task description. Data analysis with respect to the age group and the format of the task descriptions indicates significant effects (α =0.05). Thus, participants who had the support of a textual task description achieved greater performance improvement than participants who used the animated task description. Concerning the age group, participants in AG I show better performance and lower observation times concerning to participants in AG II. Furthermore, nonlinear curve fittings were carry out and root mean square errors calculated in order to investigate the accuracy of the prediction method. The results show that the prediction method is less accurate for older adults.
