摘　　要：考察联想记忆具有的可快速稳健处理信息的复杂适应性网络结构模式。以英国爱丁堡和美国佛罗里达词汇联想辞典为基础,分别构建词汇联想网络进行复杂网络分析。两大词汇联想网络既有短连接路径性、高云集性以及中心度幂律分布的共同特征,又存在联想关系的差异。虽然联想记忆的内容受到社会文化背景等因素的影响,但其基本结构组织模式符合利于快速信息提取的小世界结构和利于适应性信息存储的无标度特征。Structure patterns of quick and robust information processing in complex adaptive networks of associative memory was studied. Word associative networks were constructed by using Edinburgh Association Thesaurus and Florida Association Thesaurus, which were collected in British and American respectively. These networks were analyzed by complex network analysis. The two word associative networks had common features of short average shortest path lengths, large average clustering coefficients and powerlaw centrality distributions, and meanwhile these two networks had different associative relationships with each other. Despite social culture influences on its detailed contents, associative memory has a smallworld structure for quick retrieval and a scale-free property for adaptive storage.
