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.

Current projects
   - Assessment and treatment of hemispatial neglect (development of the Virtual Reality Lateralized Attention Test - Video / YouTube)
   - The role of context in the pattern of action-related interference from distractor objects (with Chia-Lin Lee and Solene Kalenine
   - Investigating brain regions critical for resolving conflict between multiple actions associated with the same object (with Christine Watson)
   - Assessing the effects of left hemisphere stroke on action knowledge automatically evoked by semantic processing tools (with  Christine Watson)
   - Testing whether Transcranial Direct Current Stimulation (tDCS) can improve tool-use in patients with apraxia (with Steve Jax and Matthieu DeWit)
   - Investigating prediction abilities of parietal and non-parietal stroke patients (with Matthieu DeWit)
