Cognition and Action Laboratory


We investigate the interface between cognitive representations of objects, tasks, and action planning processes using behavioral testing with healthy and brain-damaged participants, voxel-based lesion analyses (VLSM), Transcranial Magnetic Stimulation (TMS; in collaboration with Branch Coslett and Steve Jax), eyetracking (in collaboration with Dan Mirman), and Virtual Reality. This work enables us to understand how conceptual representations may be “embodied”, and the aspects of object representations that may be disrupted after stroke to frontal, temporal, or parietal brain regions. In addition, we study the role of spatial and body representations in the control of attention and action.
