Research Interest: | Combining fMRI, EEG, and TMS with psychophysics, my research interests focus on implicit cognition, interpersonal relationships, and the role of the mirror neuron system in intention understanding. I develop high-resolution techniques to unravel how an individual's automatic (non-conscious) gestures are a direct reflection of that individual's brain neurocircuitry. The emphasis is on elucidating the cognitive chronoarchitecture that underlies action representation and an understanding of desires and motor intentions performed by other people. Connecting self-expansion model and theories of cognitive interdependence in dyads, I aim to develop a predictive model of automatic cognitive information processing in interpersonal relationships. |
