The processing of object semantics in extra-foveal vision. Evidence from healthy and pathological populations.

The processing of object semantics in extra-foveal vision. Evidence from healthy and pathological populations.
-

In vision science, a topic of considerable interest and controversy is the processing of objects that are (in)consistent with the overall meaning of the visual context in which they occur. In particular, it is yet unclear whether object meaning can be processed in extra-foveal vision and how much time is needed to do so. In this talk, I present a series of eye-tracking studies (one with co-registered EEG responses) on a widely cross-sectional sample of healthy and pathological individuals (i.e., Alzheimer Dementia patients), tested on different tasks (visual search vs. change detection) across a variety of visual contexts (arrays of standalone objects vs. naturalistic scenes). All studies converge to the very same result: object semantics is, at least partly, processed in extra-foveal vision and used to guide the allocation of early overt attention, even by the AD group.
