Set-theoretic and network models reconsidered: A comment on Hollan's "Features and semantic memory"

Argues that the choice of a network or set-theoretic representation correlates with 2 substantive differences among models of semantic memory. First, in explaining certain reaction time effects, networks models emphasize retrieval processes, while set-theoretic models often emphasize comparison processes. Second, set-theoretic models posit more semantic analysis during sentence verification than do network models. J. D. Hollan's (see PA, Vol 54:Issue 4) recent demonstration of an isomorphism between set-theoretic and network representations cannot resolve these important issues.
