Within the network, the only reference to extensionality is via a mechanism to assert that two intensions have the same extension in same world. This framework is employed in three application problems to illustrate the nature of its solutions.<\/jats:p><jats:p>The formalism used here utilizes only assertional information and no structural, or definitional, information. This restriction corresponds to many of the psychologically motivated network models. Some of the psychological implications of network processes called node merging and node <jats:italic>splitting<\/jats:italic> are discussed. Additionally, it is pointed out that both our networks and the psychologically based networks are prone to memory confusions about knowing unless augmented by domain\u2010specific inference processes, or by structural information.<\/jats:p>","DOI":"10.1207\/s15516709cog0604_1","type":"journal-article","created":{"date-parts":[[2005,7,5]],"date-time":"2005-07-05T12:58:18Z","timestamp":1120568298000},"page":"291-330","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":67,"title":["Intensional Concepts in Propositional Semantic Networks*"],"prefix":"10.1111","volume":"6","author":[{"given":"Anthony S.","family":"Maida","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stuart C.","family":"Shapiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,2,11]]},"reference":[{"key":"e_1_2_1_2_1","volume-title":"A plan\u2010based approach to speech act recognition","author":"Allen J.
