Editing ACT-R (section)

===Memory, attention, and executive control===
The ACT-R declarative memory system has been used to model human [[memory]] since its inception.  In the course of years, it has been adopted to successfully model a large number of known effects.  They include the fan effect of interference for associated information,<ref>Anderson, J. R. & Reder, L. M. (1999). The fan effect: New results and new theories. ''Journal of Experimental Psychology: General'', ''128'', 186–197.</ref> [[Primacy effect|primacy]] and [[Recency effect|recency]] effects for list memory,<ref>Anderson, J. R., Bothell, D., Lebiere, C. & Matessa, M. (1998). An integrated theory of list memory. ''Journal of Memory and Language'', ''38'', 341–380.</ref> and serial recall.<ref>Anderson, J. R. & Matessa, M. P. (1997). A production system theory of serial memory. ''Psychological Review, 104'', 728–748.</ref>

ACT-R has been used to model attentive and control processes in a number of cognitive paradigms.  These include the [[Stroop task]],<ref>Lovett, M. C. (2005) A strategy-based interpretation of Stroop. ''Cognitive Science, 29'', 493–524.</ref><ref>Juvina, I., & Taatgen, N. A. (2009).
