TITLE: 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.
Dr. Moreno I. Coco is a Senior Lecturer in Psychological Sciences at the School of Psychology, University of East London. Previously, he was a Leverhulme Research Fellow at the School of Philosophy, Psychology and Language Sciences, University of Edinburgh, and before that a Fundação para a Ciência e a Tecnologia post-doctoral fellow at the Department of Psychology, University of Lisbon. He obtained his PhD in 2011 at the Institute of Language, Cognition and Computation of the School of Informatics, University of Edinburgh. His work integrates experimental psychology with computational modelling to examine the cognitive dynamics sustaining the processing of visual and linguistic information, their formation and access from memory, as well as, their interactive exchange during cooperative, goal-oriented, dialogue tasks, in healthy and neuro-pathological individuals.
