About 3-4 times per second, a human observer exploring a real-world environment, makes a saccadic eye movement to a new fixation point. As a result, visual information is sampled in a series of different glimpses that are isolated in time. Our central question is how the informational contents of these successive snapshots of an object are integrated across saccades. Under the assumption that transsaccadic integration serves to expedite object recognition, we focus our research on two types of evidence that may be integrated transsaccadically: viewpoint information and semantic information. We intend to develop an account that is detailed and integrated with respect to the chronometry of the processes, to the type and location of the information that is coded transsaccadically, and to the functionality of transsaccadic object perception in the context of real-world scene exploration and motion interpretation.
Other Research Interests
perception of biological motion, action and object recognition, lexical access to nouns and verbs
