Towards Pinpointing the Neural Correlates of ACT-R: a Conjunction of Two Model-Based fMRI Analyses


The aim of this study is to provide a precise mapping of five ACT-R modules on the brain. While there exists a predefined mapping between ACT-R modules and brain regions (e.g., Anderson et al., 2007), these regions are relatively crude (cubes of ~12×12×12mm) and serve in principle only as indicators of module activity. Previously, we have shown that an analysis method called model-based fMRI can provide more detailed whole-brain mappings (Borst, Taatgen, & Van Rijn, 2011). In the current study, we applied this method to a second dataset and combined the results of both datasets to create an overall mapping.
