在刑事调查中比较人脸图像时，法医面部检查员报告说，痣等关键特征特别能诊断身份。然而，关于痣在面部识别中的功效的科学证据仍然有限。目前的研究通过操纵这些小特征的存在和位置，系统地研究了痣对面部图像比较的影响。我们发现，观察员未经训练的面部图像比较自发地使用痣，以支持识别决策（实验1）。当观察者被提示利用鼹鼠进行识别（实验2）时，这些效应被放大，并且对空间位置的细微差异敏感（实验3）。此外，识别精度较高时，观察员被指示使用痣只和分离的面部识别（实验4）。这些发现表明，观察者在面部图像比较中对痣的存在和位置很敏感，并显示了这些小的视觉特征影响识别决策的能力。
When comparing images of faces in criminal investigations, forensic facial examiners report key features such as moles to be particularly diagnostic of identity. However, scientific evidence for the efficacy of moles in facial identification is still limited. The current study systematically examined the effect of moles on facial image comparison by manipulating the presence and location of these small features. We found that observers untrained in facial image comparison spontaneously use moles to support identification decisions (Experiment 1). These effects were amplified when observers were prompted to utilise moles for identification (Experiment 2) and were sensitive to subtle differences in spatial location (Experiment 3). Moreover, identification accuracy was higher when observers were instructed to use moles only and dissociated from facial identification (Experiment 4). These findings demonstrate that observers are sensitive to the presence and location of moles in facial image comparison and shows the power of these small visual features to influence identification decisions.
