Computational Cognitive Models Lab CoCoMo Lab

Research

Research in the lab generally concerns skill learning across development. We leverage a variety of methods, ranging from Bayesian psychometric and statistical models to cognitive process models of memory and learning. Common domains of application are word and concept learning, but we are also interested in sequential action learning and statistical learning, more broadly.
