I am primary interested in examining the various ways in which object representations for items across various orientations are linked. Specifically, I'm intrigued by the notion that representations of an object in multiple orientations may start off as fairly independent of one another and gradually unite into a cohesive whole at later stages of processing, as we move from perceptual to conceptual representations. For example, in the vast face processing literature, much has been made about how upright faces are distinct and unlike inverted faces, but my research aims to test the extent (and the levels) to which these two items are truly separable from one another. One of the central questions in my research is the nature of the information that is transferred and shared across orientations, as well as the possibility for the brain to treat a single object in multiple orientations as separate, disparate items.
