The purpose of this research is to examine whether the results of statistical analyses on the basis of a language corpus correspond with human beings' language knowledge or not. In order to examine the correspondence, a psychological experiment was conducted using results of statistical analysis of a language corpus as follows: Two participants groups were asked to answer words or metaphors given referring materials chosen from the results of statistical analysis of language corpus. In the association group, 18 participants were asked to associate words from materials.In the metaphor generation group, 20 participants were asked to generate “A like B” style metaphors.The result of the psychological experiment showed the correspondence of the results of statistical analysis of a language corpus with human beings' language knowledge.Furthermore, answers of association group were compared with metaphors of metaphor generation group using relative entropy, which indicates a diversity of connections between words and latent semantic classes.The result showed that metaphors generated by the metaphor generation group were connected with more latent semantic classes than words answered by the association group
