In this article, learning curves for foreign vocabulary words are investigated, distinguishing between a subject-specific learning rate and a material-specific parameter that is related to the complexity of the items, such as the number of syllables. Two experiments are described, one with Turkish words and one with Italian words. In both, S-shaped learning curves were observed, which were most obvious if the subjects were not very familiar with the materials and if they were slow learners. With prolonged learning, the S shapes disappeared. Three different mathematical functions are proposed to explain these S-shaped curves. A further analysis clarifies why S-shaped learning curves may go unnoticed in many experiments.
在本文中，我们研究了外语词汇的学习曲线，区分了特定于主体的学习率和与项目复杂性相关的特定于材料的参数，例如音节数量。本文描述了两个实验，一个使用土耳其语单词，另一个使用意大利语单词。在这两个实验中，均观察到了S形学习曲线，当受试者对材料不太熟悉且学习速度较慢时，这种曲线最为明显。随着学习时间的延长，S形曲线消失了。本文提出了三种不同的数学函数来解释这些S形曲线。进一步的分析阐明了为什么S形学习曲线在许多实验中可能未被注意到。
