Postdoctoral research fellow, Cognition and Action Laboratory
My research interests center on the way in which dynamic human actions are represented in the mind and brain. Much research has been devoted to investigating our semantic knowledge of concrete objects, but less is known about the content and structure of action knowledge. We use our knowledge about actions to carry out actions ourselves, as with the skillful manipulation of tools, to understand the behavior of others, and possibly even to comprehend words that refer to actions.
I have used several different methodologies – computational modeling, behavioral research with healthy and neurologically-impaired individuals, voxel-based lesion-symptom mapping (VLSM), and functional magnetic resonance imaging (fMRI) – to understand the representation of action concepts. For instance, one question of interest is the degree to which action knowledge and/or action language draw upon information represented in modality-specific sensory and motor systems – the so-called “embodied” nature of cognition. I am also interested in understanding how more abstract knowledge about actions arises. That is, how is it that I can recognize that Tom and Jane are both “jumping”, even though they look nothing alike?
One current project investigates patterns of impairments after neurological injury or disease to determine if the conceptual organization of actions parallels action production. Another project focuses on identifying the organizational structure of object-directed actions and then using this structure to understand the behavior of healthy and neurologically-impaired participants on tasks that tap action concepts.
● Consistency of impairments among tests of action knowledge and action product
● The organization of actions performed with familiar objects in “action space”
● Nature of impairments to object-action knowledge in apraxia
