While a clear relation has been established between ACT-R and activity in fMRI, little is known about whether ACT-R has also correlates in EEG activity. Because of its superior temporal resolution compared to fMRI, EEG could potentially be used to adjudicate between model versions that differ in time courses of module activation, even while generating qualitatively similar patterns of behavioural data. On the other hand, ACT-R could form a much-needed source for hypotheses about interactions between brain areas (synchronization) in EEG data. I discuss a method to find such a mapping between ACT-R and EEG buffers, and apply it to data from an attentional blink experiment (Martens et al., 2006). I show preliminary EEG correlates of ACT-R modules and discuss broader implications of this approach for both cognitive neuroscience and cognitive modeling with ACT-R.
