Note That The Given Potential And To Stimulate The Characteristics Discernible Effect On Unexpected Objects

When people involved in attention-demanding tasks, they usually have a blind eye and a deaf ear to other things. This functional blindness phenomenon resulted from not paying attention to was known as Inattentional Blindness(IB). In the studies of Inattentional Blindness, researchers manipulated the characteristics of different stimulus and various types of attentional tasks to explore the influence of attentional set and object features to detect the unexpected objects. The research paradigms were different, having more controversial experimental results, and there was no systematic manipulation of the relationship between the various factors.Which characteristics of bottom-up and top-down regulation of attentional set factors involved in to affect the probability of detection, and how did they interact? Whether the Observers will establish attentional set based on a higher level of classification? In this study, we used dynamic Inattentional Blindness paradigm, showing four 2×2 between subjects experimental design, and systematic manipulated features and meanings between the attended objects and the unexpected object, to explore the impact of attentional set, object feature and semantic category to affect the probability of Inattentional Blindness.Experiment 1 examined the impact of distinct characteristics and attentional set to the detection of the unexpected object by manipulating the distinction of attentional set-related dimensions and non-related dimensions. Experiment 2 examined the impact of similarity and attentional set to the detection of the unexpected object by manipulating the similarity of attentional set-related dimensions and non-related dimensions. Experiment 3 systematic manipulated the significance and the similarity of object features and attentional set to explore the interaction between top-down attentional control and bottom-up stimulus features to impact the Inattentional Blindness. Experiment 4 presented dynamic picture materials, examining stimulus types and the consistency of semantic category to affect the detection of the unexpected object.Experiment 1 confirmed distinction effect of the unexpected objects in attentional set-related dimensions. We found that the unexpected objects in attentional set-related dimensions unexpected objects were significant, the detection increased, reducing the probability of Inattentional Blindness. It confirmed the role of bottom-up stimulus features. Experiment 2 confirmed similarity effect of the unexpected object and attentional set-related dimension. We found that the unexpected objects in attentional set-not-related dimension were similar to attended objects, the probability of Inattentional Blindness reduced. The results supported the theory of selective attention based on the objects. Attention selected the independent objects and object features, the significance of physical characteristics, the similarity and semantic category have contributed to notice the unexpected objects.Experiment 3 confirmed that the interaction of bottom-up stimulus features and top-down attentional set affected the the probability of Inattentional Blindness of the unexpected object. Significant stimulus would not always automatically capture attention, It could be adjusted by the Observers' top-down attentional set. When attentional set-related dimension was similar to the unexpected object, It would be more likely to be noticed. Although the significance of stimulus' bottom-up increased the possibility of attentional capture, the most critical factors affecting the the probability of Inattentional Blindness were Observers' top-down attentional set.Experiment 4 confirmed that the expected stimulus, which were semantic relevant and physical irrelevant with attended objects, were more likely to be noticed. Observers can established attentional set based on a higher level of classification. The words in the same semantic category of attentional set could generate less Inattentional Blindness rate than the same picture stimulus. The results support Lavie's perceptual load model. When Observers established attentional set based on the semantics types of object, the perceptual load was higher, Inattentional Blindness rate was higher, It will not process irrelevant stimulus or only on the surface.
