We developed a Training System for the Logic of English Text (TLET) to help learners develop the understandings of the logic of English text. Moreover, an empirical study was conducted to investigate how cognitive styles affected learners' perception for the use of the TLET. The results indicated that Holists and Serialists preferred to use the position hint to solve problems. Besides, they thought that the hint of English explanation was not useful for them. On the other hand, Holists slightly relied on the answer hint to complete the tasks while Serialists would like to complete the tasks independently. Additionally, extra functionalities suggested by Holists and Serialists were also different. In brief, of this research contributes to provide a deep understanding of the different requirements of Holists and Serialists when they using the TLET. Such an understanding can be applied to develop a personalized TLET.
