The Impact Of The Search Task On Attentional Capture

The individual will establish a notice window in the pre-attention stage,and all elements in this window will be processed in a bottom-up manner;Existed in the whole stage of the top-down process,but will only appear in the build window,and then all of the target is significant as the priority processing one by one,at this point in the window of significant content will be the first concern,namely appear attention to capture effect.Theeuwes(2010)proposed a suggestion,it should note that the window size(size)and significantly associated with distraction,through studying distracted the attention of the capture effect can be concluded that pay attention to the nature of the window.Through four experiments,the study explored the changes of the attention window by exploring the capture of the attention of the distracter.One experiment with Theeuwes classic experimental paradigm,the same amount of search task to pay attention to the influence of capture,it is found that the number of elements has no effect on pay attention to the window,both in the number of more or less,pay attention to the window is out of the state of the broad;Experiment 2,discuss the influences of search mode to pay attention to the window,found the note that the effect of the capture is consistent,that search pattern is no effect on pay attention to the size of the window,whether using feature only search pattern search patterns or characteristics,pay attention to the window will be in a state of broad;Experiment three to explore the significance of the target to pay attention to the influence of the window,the results show that when the target significant decline,namely task difficulty increased after distraction by attention to catch has increased,indicating that note will become narrow window(relative to baseline),but still in a state of broad;Experiment four,discuss the influences of the dynamic changes of the elements to pay attention to the window,it was found that when the number of elements in search task in dynamic change,is no longer a constant value,the attention of distraction capture effect disappeared,note will become the most narrow window at this time.The above results show that the attention capture will not be affected by the number of elements in the search task and will not be affected by the search strategy.But as the task became more difficult,the distraction received increased;When the search task is not a fixed number of elements,the attention of the distractor will disappear,indicating that the distractor is no longer in the window.The above results show that,note the nature of the window has a more stable,only when the individual change when confronted with a task more difficult to search,the second is in unpredictable number of search task,individuals use the attention of a relatively narrow window.
