The Semantic Inconsistent Effects Of New Object Indentification In Scene Perception

Visual information is the main source human obtained from the objective world, it is also an important functional approache of human cognitive the world. Research in human vision is an important part on basic and experimental psychology, it can be divided into three areas of investigation:The low-level vision, the intermediate-level vision and the high-level vision. The highest level concerns the mapping from visual representations to meaning and includes the study of processes and representations related to the interaction of cognition and perception, including the active acquisition of information, short-term memory for visual information, and the identification of objects and scenes. The identification of objects and scenes is the problem researchers most concerned, it is also the most controversial issue.The rencent researches on processing features and mechanisms of new objects in the scene have not yet form a unified understanding. The issues focused mainly on the semantic effects and the mechanism of processing and identification of the new objects in scene. Looking at existing researches, the researchers used different experimental materials, methods, etc. Different studies obtained conflicting findings, there is some studies found that consistent objects in the scene is easier to be identification, there is some studies found that inconsistent objects are easier to be identification, and some studies found that consistent or inconsistent objects in identifying have no advantages. In order to better answer the complexity questions of how to process and identify of the objects in scene, the present study uses full-color real scene pictures, and design two experiments of abrupt onset and non-abrupt onset, recorded the eye movement respectively when subjects observed the pictures of the scene, on different levels of processing conditions and the semantics of consistent or inconsistent objects, analyzing the characteristics and laws when processing the new objects affected by the scene semantic background, and further analysis the effect of attentional and memory when processing and identifing a new object in scene.In this study, the results were concluded as follows:(1) Full color real scene images were used in this study, discovered a significant semantic inconsistent effects in processing new object in scene, inconsistent objects faster capture attention and need more perceptual processing than consistent objects.(2) The degree of processing affected to process the abrupt onset of the new objects only at the initial stage, under the conditions of fully processed, new objects capture attention priority.(3) The degree of processing affected to process the new objects for non-abrupt onset, under the conditions of fully processed, new objects got priority and deeper processing.(4) Comparing the two experiments found that new objects with the transient motion signals appearing not only captured attention faster but also got individuals' more processing on it, and left a deeper memory trace.
