The Influence Of The Attributes And Semantic Relations Of The Object In Scene Perception On The Blindness Of Change

Change blindness is a phenomenon in which even obvious details in a visual scene change without being noticed.Robust change blindness can occur even in familiar and well known mental secens.Human activity is constantly receiving and responding process.The environment information is received by all kinds of feelings of human organs,the visual information is the main source of information.In the processing of human visual information,a large amount of information has been made by the visual pathway to the brain,or only a small amount of information is part of the visual system and the brain selectively processed.The scene is the basic unit of human cognition around the world,human beings are the scene to characterize the environment and feel the world.The individual perception of the scene information has been a concern of researchers.In recent years,with the visual perception research,specific research methods and technical means to enhance scene perception has also become a hot research topic in cognitive psychology and experimental psychology.More and more researchers to explore fine how people perceive and process the scene,the scene of object change blindness also attract more attention.The research of change blindness in real scene has important reference value in many fields,such as advertising,driving,aerospace and aviation,etcThis study from the physical property of the object to the property relationship between the object and the scene,in order to study the generating mechanism and characteristics of change blindness in the scene through the three series of studies using different paradigms,in order to understand the change blindness and attention,perceptual representation etc..The first study on problems in the current study of structure and feature attributes of change detection,using a forced choice paradigm,through 3 experiments to explore the specific location,color object of these two attributes in scene perception changes in the detection task is automatic processing or consciousness processing,and the mutual influence between these two attributes at the same time,try to study the gender differences in change detection and blindness in these two kinds of property.The study on the scene in the selection of artificial scene low level vision research,the research is extended to two will study a real visual scene of high level of the selected color picture more real scene as stimuli,with a combined method of forced choice and eye movement paradigm,in the further understanding of the real scene change blindness as the mechanism and gender differences produced by 2 specific experiments.The third study is based on two previous studies,further investigation in real scene and object background information was two in the role of the change detection task.Study on color image of the real scene is still selected,mechanism of consistency of the relationship between the object and the background and object detection of significant changes in awareness and recognition tasks,analysis of the background and object consistency effect mechanism in change detection and recognition in the process of change is consistent with 3 specific experiments,and the use of eye movement Paradigm Analysis of the background and object of consistency significantly influences the allocation of attention.The results show that the structure and feature attributes change of object perception of the scene detection process with different processing methods,structural properties of objects is in automatic processing in scene perception,is not affected by the cues.The processing structure property of the object will affect the machining feature,object location attribute changes,produced to detect color properties was more obvious as the blind.The attributes of object in scene perception in the process of processing on the structure property is not affected when the color attribute changes,the observer can still complete the change of location attribute detection,change blindness phenomenon reduced.No gender differences in the three experimental study in.Study on the experimental results of two found in the real scene,the main effect of the two kinds of attribute structure and feature attributes of the object is not significant,there is no gender difference.In male and female subjects in the processing of real scene change detection position and color in the process of two kinds of properties of the same.Girls are easier to detect the object color change detection of position change appears more blindness phenomenon.Change the boys on the scene in the object of the two properties to detect no difference.Study on the experimental results of three found in the primary change detection task,there is a significant effect of visual and semantic coherence effect,namely high significant object in the scene is more easy to see,the object is not consistent with the scene is more easily perceived,and the object is consistent with low significant object and information and the presence of background scene change blindness phenomenon.Changes in the recognition task,the influence of the change of object recognition and processing of semantic consistency by early and late in the top-down semantic theme of two significant conditions.Found in the change detection process through the eye movement index,was only in the primary stage of awareness of change detection will attract attention,and consistency in the background can quickly attract attention,but also make the object is not consistent with the background information is more cognitive processing.The conclusion of the study:1.In the artificial scene,the structure property of the object is a priority in the process of scene perception,and changes in the structure of property will affect the change detection feature,change attributes does not affect the structure change of attribute detection.2.Changes blindness in the scene artificial did not show gender differences.3.The real scene perception process due to the scene of more top-down information summary,will be affected by more top-down information in the process of the scene of the picture,weaken the effect of physical properties of the object.4.The object detection performance changes in different properties on different gender,male showed the same changes in the detection of object location and color while female appear differentiation,to detect the changes of location of the object color change detection of girls is better than girls,when the object position changes,there has been a change in the blind more apparent.5.The scene changes the properties of the object detection there is a gender difference in the eye movement index,the specific performance of the female in the region of interest is the average fixation time is short,short residence time,watching distance,watching a few times,especially in the processing of the object attributes of color than male.
