Learning Hours 120 (36L;84P)


Computational cognitive models are different from artificial intelligence systems in that the objective is to perform specific tasks as humans do, including making errors in the same way that humans do. Though usually more complex, and more difficult to evaluate, cognitive models often use problem solving techniques that are simar to those used in artificial intelligence. As almost all existing cognitive models are programmed in LISP, this course starts off with instruction that will enable the students to become proficient in that language, and to be able to take advantage of the language capabilities that have led to LISP's popularity for cognitive modelling. Students gain practical experience by implementing some typical artificial techniques as assignments. Several existing cognitive modelling systems are examined in detail, including the testing, and modification of the models' source code, when available. The evaluation of cognitive modelling systems is somewhat different that the typical evaluation of program performance because it involves statistical relations with results from human experimental studies. Within the course, students become familiar with these evaluation techniques.
