It is important to get information from the visual channel. however, Attention is a energy limited information processing system, therefore.Visual Attention Capture has been the research focus in cognitive psychology,and capture depended on the guidance from the content of working memory.Some researchers proposed that stimuli compete for selection at multiple levels of representation, with the'winner'gaining control of both perceptual and response systems.Within this framework, Working Memory acts to bias the competition for attention to favor objects that fit the goals of the task.On the theoretical basis of the contents of working memory to guide visual attention capture,working memory would affect Inattentional blindness? Inattentional blindness refers to when the observers focus attention on an object or event, they often can not be aware of significant, unusual objects. How? Affected by factors such as perceptual load .In our study,we used explicit visual attentional capture program,which is a typical static Inattention Blindness Paradigm,to examine Inattention Blindness from the guidance of the content of working memory and whether it is automatic. In other words, whether the role of the guide is also affected by some factors, such as perceptual load. The setting can be fully explored the contents of working memory to improve Inattentional BlindnessThe experiment one's result showed that when the unexpected stimulus which matched the content of working memory,and it has got a significantly perceived lever, indicating the contents of working memory could guide Inattentional blindness on a purely semantic level. The experiment two's result showed that when the unexpected stimulus which matched the content of working memory,and it has got a significantly perceived level, even that perceptual load couldn't affect. However when the unexpected stimulus unmatched the content of working memory and it got significantly perceived lever between high perceptual load and low perceptual load,indicating Inattentional Blindness from the contents of working memory's guidance didn't depend on perceptual load ,and it is a relatively automated information process, also indicating that Inattentional Blindness from the contents of working memory's guidance in the early capture stage of visual attention.To sum up, compared to previous studies, this study was a breakthrough in the following areas: (1) Most of previous studies focused on whether the interaction between working memory and visual attentional capture is.Our study further explored visual attentional capture from the contents of working memory'guidance is also affected by some factors,such as perceptual load. Therefore, our study has involved in a guiding role to explore their relationship.(2) Most of previous studies looking at implicite visual attentional capture from the contents of working memory's guidance,but Inattentional blindness is a typical of explicit attentional capture phenomenon.Our study has done Inattentional Blindess from the contents of working memory's guidance taking the lead. It not only expands study content, but also discussed Consciousness selective from the contents of working memory'guidance. (3) The innovation of our study in two aspects.on the one hand, our study took the lead in Inattentional Blindness from the contents of working memory'guidance with a purely semantic matching lever,and the guidance didn't depend on perceptual load,which provided relative automatic guidance with Strong evidence.On the other hand, the result showed attentional capture based on the task settings.which combined the Folk (1992)'propose,the same hypothesis-driven and Most (2001)'s hypothesis that similarity-capture.And also provided a comprehensive view when took place the visual attention selective not only rely on task requirements but on load.
