Comments on several quantitative approaches to semantic knowledge representations (the focus of this special issue). Points out some of the ways in which Latent Semantic Analysis and Hyperspace Analog to Language fall short of being plausible theories about psychological reality.

Cued recall for sentences in which the semantic function of actor and…

Sentences were constructed along the lines of subject-verb-object and were presented in three experiments: free recall of isolated sentences, prompted…
