在社会上重要的视觉搜索任务中，如行李检查和诊断放射学，专家错过的目标比期望的要多。计算机辅助检测（CAD）程序是专门为提高这些专业搜索任务的性能而开发的。例如，在乳腺癌筛查中，许多CAD系统能够检测到大约90%的乳腺癌，每张图像大约有0.5个假阳性检测。然而，CAD在临床环境中的益处往往很小（Birdwell, 2009）甚至没有（Meziane et al., 2011; Philpotts, 2009）。CAD系统所做的标记可以是“二进制的”，在信号高于某个阈值的任何位置给出相同的信号。另一种方法是，CAD系统给出一个模拟信号，该信号反映了某个位置的信号强度。在报告的实验中，我们使用非专家观察者和由两个噪声信号定义的人工刺激来比较模拟和二进制CAD演示：一个可见的颜色信号和一个通知我们模拟CAD系统的“不可见”信号。我们发现模拟CAD通常比二进制CAD产生更好的整体性能。在高目标患病率和低目标患病率情况下，模拟效果相似。我们的数据表明，CAD信号的形式可以直接影响性能。模拟CAD可以使计算机对搜索者更有帮助。
In socially important visual search tasks, such as baggage screening and diagnostic radiology, experts miss more targets than is desirable. Computer-aided detection (CAD) programs have been developed specifically to improve performance in these professional search tasks. For example, in breast cancer screening, many CAD systems are capable of detecting approximately 90% of breast cancer, with approximately 0.5 false-positive detections per image. Nevertheless, benefits of CAD in clinical settings tend to be small (Birdwell, 2009) or even absent (Meziane et al., 2011; Philpotts, 2009). The marks made by a CAD system can be “binary,” giving the same signal to any location where the signal is above some threshold. Alternatively, a CAD system presents an analog signal that reflects strength of the signal at a location. In the experiments reported, we compare analog and binary CAD presentations using nonexpert observers and artificial stimuli defined by two noisy signals: a visible color signal and an “invisible” signal that informed our simulated CAD system. We found that analog CAD generally yielded better overall performance than binary CAD. The analog benefit is similar at high and low target prevalence. Our data suggest that the form of the CAD signal can directly influence performance. Analog CAD may allow the computer to be more helpful to the searcher.
