Welcome to Cognitive Modeling and Computational Linguistics (CMCL) 2015, a one-day workshop to be held in conjunction with the Conference of the North American Chapter of the Association for Computational Linguistics – Human Language Technologies (NAACL-HLT 2015), taking place Thursday, June 4th in Denver, Colorado, USA.. This workshop provides a venue for work in computational psycholinguistics: computational  and mathematical modeling of linguistic representation, development, and processing. We are inviting contributions that apply methods from computational linguistics to problems in the cognitive modeling of any and all natural language abilities.
