心理词汇包含了一生中获得的词汇知识。一个核心问题是,这些知识是如何构成的,并随着时间的推移而变化。在这里,我们建议表示这个词典作为一个网络,由节点,对应于单词和链接recrucecting两个节点之间的关联关系,基于自由关联数据。心理词汇的网络观点是许多认知理论所固有的,但工作模型的预测强烈依赖于现实的规模,涵盖日常交流中使用的大多数单词。将大型网络与网络科学的最新方法相结合,使我们能够同时回答有关其在不同尺度上的组织的问题,例如:考虑到全球网络架构,词汇知识的有效性和鲁棒性如何?词汇在心理词典中的组织原则是什么(即主题与分类)?与相邻单词的局部连通性如何解释为什么某些单词比其他单词处理得更有效?从单词联想构建的网络特别适合于解决突出的心理现象,如发展变化,创造力的个体差异,或精神分裂症等临床状态。虽然这些现象可以使用这些网络进行研究,各种未来的挑战和方式,这一建议补充其他观点也进行了讨论。
The mental lexicon contains the knowledge about words acquired over a lifetime. A central question is how this knowledge is structured and changes over time. Here we propose to represent this lexicon as a network consisting of nodes that correspond to words and links reflecting associative relations between two nodes, based on free association data. A network view of the mental lexicon is inherent to many cognitive theories, but the predictions of a working model strongly depend on a realistic scale, covering most words used in daily communication. Combining a large network with recent methods from network science allows us to answer questions about its organization at different scales simultaneously, such as: How efficient and robust is lexical knowledge represented considering the global network architecture? What are the organization principles of words in the mental lexicon (i.e. thematic versus taxonomic)? How does the local connectivity with neighboring words explain why certain words are processed more efficiently than others? Networks built from word associations are specifically suited to address prominent psychological phenomena such as developmental shifts, individual differences in creativity, or clinical states like schizophrenia. While these phenomena can be studied using these networks, various future challenges and ways in which this proposal complements other perspectives are also discussed.
