Editing ACT-R (section)

===Complex tasks===
ACT-R has been used to capture how humans solve complex problems like the Tower of Hanoi,<ref>Altmann, E. M. & Trafton, J. G. (2002). Memory for goals: An activation-based model. ''Cognitive Science'', ''26'', 39–83.</ref> or how people solve algebraic equations.<ref>Anderson, J. R. (2005) Human symbol manipulation within an integrated cognitive architecture. ''Cognitive Science, 29(3)'', 313–341.</ref> It has also been used to model human behavior in driving and flying.<ref>Byrne, M. D., & Kirlik, A. (2005). Using computational cognitive modeling to diagnose possible sources of aviation error. ''International Journal of Aviation Psychology, 15'', 135–155. {{doi|10.1207/s15327108ijap1502_2}}</ref>

With the integration of perceptual-motor capabilities, ACT-R has become increasingly popular as a modeling tool in human factors and human-computer interaction.  In this domain, it has been adopted to model driving behavior under different conditions,<ref>Salvucci, D. D. (2006). Modeling driver behavior in a cognitive architecture. ''Human Factors'', ''48'', 362–380.</ref><ref>Salvucci, D. D., & Macuga, K. L. (2001). Predicting the effects of cellular-phone dialing on driver performance.
