Linear Discriminative Learning (LDL) is a computational implementation of Word and Paradigm Morphology (Blevins, 2016).  Embracing and formalizing the idea of paradigmatic analogy while staying away from the assumptions underlying decompositional theories, LDL provides a morpheme-free model of the mental lexicon that learns the implicit associations between high-dimensional representations of words’ forms and semantics. 

In this course, a lecture series will introduce the theoretical background and the design of the LDL model for the mental lexicon, as well as review modeling results obtained for a wide range of tasks (e.g., visual and auditory word recognition, speech production, nonword processing) across different languages.

A series of lab sessions, including hands-on exercises, will introduce participants to working with the LDL software as implemented in the R package WpmWithLdl, covering data preparation, model building, model evaluation, and the analysis of experimental response variables with model-based predictors.

This course will enable participants to build and test their own LDL models, and to evaluate the strengths and weaknesses of this computational implementation of the mental lexicon.
