The Inconsistency Effect Of Attentional Bias In Scene Perception

The visual scene contains a large amount of information,but human beings can sample an d process at a certain time is very limited.Although there are so much information,people stil 1 can effectively access information through the visual system and cognitive system in complex scene complex information,in order to realize the interaction between humans and the environ ment.The people in the process of understanding in the scene is not only a simple list of obje cts and background in the scene,it also contains a specific characterization of all the relations between entities in the scene.An effective way to study the mechanism of scene processing is to use the consistency bet ween objects.Research on how people to carry on the processing of the scene and the objects in the scene.A consistent relationship between objects and scene can be divided into two categ ories:semantic consistency and syntactic consistency.Semantic consistency refers to the possbili ty that an object appears in a particular scene,that is,the matching between the meaning of th e object and the meaning of the scene.Syntactic consistency refers to whether the object appea rs to obey the laws of physics that spatial relationship between objects and scene fit in the sce ne.Of the two processing activate different electrophysiological responses and different brain re gions,more important is the consistency between syntactic and semantic consistency between re al objects in the environment are often exist at the same time,so the two are separated and st udied is obviously insufficient.This research object scene,semantic consistency and syntactic consistency between the com bination,set the scene in the object in the case was briefly presented during the scene pictures recorded by real-time eye movement,which can differences on the temporal and spatial variatio n of biased attention scene processing exploration scene consistency effect is more ecological;t here is no scene by setting,suggesting that the two experimental conditions,the influence of pr ocessing mode in the top-down and bottom-up based processing methods,scene semantic consis tency and syntactic consistency processing of attentional bias effect produced.According to the research results,the conclusions are as follows:1 Scene consistency processing show obvious advantage on Inconsistent processing,in proc essing of inconsistent objects show more attention bias,inconsistency of the object more watchi ng more times,longer fixation duration,shorter latency and longer time of saccadic gaze,occu py more proportion in the whole time watching and watching on;2 In addition to the semantic consistency,the consistency of syntax also affects the attentio n distribution in the scene processing;3 Under the condition of With or without scene hints,the eye movements in the scene co nsistency processing are similar,the biggest difference is reflected in the first fixation latency a nd average saccade latency in interest area,mainly illustrate the top-down and bottom-up orient ed processing methods will affect the distribution of attention in the processing of the scene.
