摘要
在安检任务中,事件率很低时漏报率迅速升高,该现象被称为"低事件率效应"。本文通过比较高、低视觉复杂度条件下的漏报率和判断标准来探讨如何削弱该效应,结果表明降低视觉复杂度能削弱但不能完全消除低事件率效应,低事件率效应的产生不能完全用判断标准的变化来解释。
The low prevalence effect is that miss errors increased markedly when target prevalence was low in X - ray luggage screening tasks. With a simulated X - ray luggage screening task, the present study found that lower visual complexity did not cure the low prevalence effect,but weakened it, and the change of subject＇s criterion was not the only reason for the effect.
