摘要:: 认知风格是人们在信息加工方式上的个人偏好，是运用以大脑为基础的神经结构和机制进行信息加工的个体差异。本研究在词汇学认知风格模型的基础上，采用SOM神经网络的方法，对参与测试的240 名大学生（平均年龄19.6 岁）进行聚类分析。结果显示，大学生的认知风格可以聚为四类，它们是细致灵动型、粗放灵动型、讨论型和规范型。每一类型的大学生在认知风格上具有最大的相似性，而不同类型的大学生认知风格差异较大。研究还产生了9 种更加具体的认知风格类型。

Abstract:: Cognitive style refers to the individual preferences in the way of processing information and theindividual differences in the neurological structure and mechanism of information processing. On the basisof a lexicological model of cognitive style， this study is intended for a categorization of 240 undergraduates（mean=19.6） according to their cognitive style by using the SOM Neural Network. The result shows that thecollege students fall into the following four groups in terms of cognitive style： precise and flexible； imprecisebut flexible； dialogical； and normative. The students under investigation show great similarity within the samegroup but significant differences between different groups. This study has also identified 9 specific types ofcognitive style.
