Object-based Inhibition Of Return In Static Paradigm And Dynamic Paradigm

Inhibition of return(IOR)is a phenomenon that people react more slowly to a stimulus that have been paid attention to.This performance can decrease the possibility's attention to the location attended,which is help for improving the efficiency of visual search.The reference frame of IOR has been one of the hotly debated theoretical questions in this field.Previous studies have found object-based IOR in a rotation dynamic paradigm.But it is a question whether object-based IOR exists in static paradigm because of a blend of object-based IOR and location-based IOR in static paradigm.At the same time,eye movement separates retinotopic IOR and spatiotopic IOR and background movement separates object-based IOR and location-based IOR.The common feature between spatiotopic IOR and object-based IOR is that the object is tagged inhibition.And the difference is the method to separate.One is eye movement,and another is background movement.A previous study has found spatiotopic IOR but not object-based IOR and held a opinion that predictive remapping works through efference copy once eye moves,which maintains visual stability.But another study has showed that action control,sensorimotor adaption and spatial memory have remapped background.So,the question whether object-based IOR exists without efference copy in a background movement dynamic paradigm is a theme worthy of discussion.The aim of this thesis is to explore whether object-based IOR exists in static paradigm and dynamic paradigm.Experiment one is to explore whether object-based IOR exists in static paradigm.Adding a fixation point in the experiment is to exclude other reference frame of IOR's influence.The result shows the existence of object-based IOR.Experiment two is to explore whether object-based IOR exists in dynamic paradigm.The result shows nothing.Experiment three similar to experiment two,is to simulate real scene.But the result does not show the existence of object-based IOR,too.Even there isn't overal IOR.Maybe it is related to the materials and procedure of experiment.These results shows that object-based IOR exists in static paradigm but not in dynamic paradigm,which means action control,sensorimotor adaption and spatial memory dosen't remap the background.Efference copy maybe the key.
