Computational frameworks that differ in the types of variables they represent and whether or not they represent a sequence of events or choices. Three of the cells cite previous researchers who have used these frameworks to model aspects of cognition. Although Bayes nets, Markov models, and Markov decision processes have been used by psychologists, decision nets have not yet been explored as psychological models.
