Title: Context, cues, conflict and cognitive control in ACT-R


I will discuss the modeling of cognitive control in the ACT-R cognitive architecture. I will frame my discussion with the distinction between reactive and proactive modes of cognitive control (Braver et al 2007). I will argue that a complete theory of cognitive control needs to explain both modes of control and mechanisms for their interaction. The contextual memory for goals (CMFG) model will be presented as a theory of cognitive control implemented in ACT-R. CMFG proposes mechanisms for reactive control using learned contextual cues, proactive control using active maintenance and intentional weighting, and the interaction between reactive and proactive control using conflict detection. I will contrast my proposals with the Threaded Cognition Theory (Salvucci & Taatgen, 2008, 2010).
