Our paper on Speed/Accuracy Tradeoff in ACT-R Models of the Concentration Game Game has appeared in the 2013 International Conference on Cognitive Modeling.
This paper describes the development of subsymbolic ACT-R models for the Concentration game. Performance data is taken from an experiment in which participants played the game under two conditions: minimizing the number of mismatches/turns during a game, and minimizing the time to complete a game. Conflict resolution and parameter tuning are used to implement an accuracy model and a speed model that capture the differences for the two conditions. Visual attention drives exploration of the game board in the models. Modeling results are generally consistent with human performance, though some systematic differences can be seen. Modeling decisions, model limitations, and open issues are discussed.
I attended the Foundations of Digital Games 2013 conference, held this year on the island of Crete, Greece. While there, I presented my early Doctoral Consortium work on inferring cognitive behaviors from low-level user interactions in games. If nothing else, the venue provided some closure for my past work as a formal games researcher.
I am pleased to announce that I have accepted an offer to intern at Google this summer, from May 28 to August 23. I will be working with the Search team in Mountain View, California.
Like last year, I once again participated in NEA’s Read Across America. I read “Alexander and the Terrible, Horrible, No Good, Very Bad Day” to a classroom of second graders at Wildwood Forest Elementary.
After the story, the students asked many tricky questions about game development and game design. Some days are like that, even in Australia.
