The human visual system is still an important factor in military warfare; military personnel receive training on effective search strategies, and camouflage that can effectively conceal objects and personnel is a key component of a successful integrated survivability strategy. Previous methods of camouflage assessment have, amongst others, used psychophysics to generate distinctiveness metrics. However, the population from which the human observers are drawn is often not well defined, or necessarily appropriate. In this experiment we designed a new platform for testing multiple patterns based on a camouflaged object detection task, and investigate whether trained military observers perform better than civilians. We use a two-alternative forced choice paradigm, with participants searching images of woodland for a replica military helmet displaying Olive Green, Multi Terrain Pattern, US Marine Pattern or, as a conspicuous control, UN Peacekeeper Blue. Our data show that there is no difference in detection performance between the two observer groups but that there are clear differences in the effectiveness of the different helmet colour patterns in a temperate woodland environment. We conclude that when tasks involve very short stimulus presentation times, task-specific training has little effect on the success of target detection and thus this paradigm is particularly suitable for robust estimates of camouflage efficacy.  相似文献

As many states in the Middle East are considering whether to embark on nuclear power programs, there is an urgent need to develop confidence-building measures to reassure states in the region that the programs are peaceful. One possible path would be to consider multilateral approaches to the fuel cycle in order to foster nuclear cooperation between states in the region, instead of each state going it alone, which would likely increase suspicions and the risk of a cascade of nuclear proliferation. With its policy of “zero problems with neighbors,” strategic connection to the West, and long-standing experience in the nuclear field, Turkey would be well-placed to take the lead on such a nuclear confidence-building agenda. Over time and under the right political conditions, Turkey could initiate or participate in measures including cooperation on nuclear education, safety and security, research and development, and joint fuel cycle facilities such as a regional fuel fabrication center.  相似文献
