| 摘要： | This report includes a review of the results of three experiments conducted by researchers at Johns Hopkins University under a Federal Aviation Administration research grant. This research supports the Transportation Security Laboratory's Human Factors Long-Term Research Program. The purpose of this research is to develop a theoretical understanding of the cognitive processes involved in various security tasks. The research described in this report is most relevant to the X-ray screener search task. Experiment I examined the effects of size and brightness on the unintentional capture of attention during a target search task. Unintentional capture occurs when a non-target draws attention away from the target. Experiment 2 examined basic search processes by looking at how the placement of multiple targets effects detection. Experiment 3 addressed the different types of search strategies a screener might use during a search task. |
