We directly compared recognition for faces following 0 degrees-75 degrees viewpoint rotation about the yaw, pitch, and roll axes. The aim was to determine the extent to which configural and featural information supported face recognition following rotations about each of these axes. Experiment 1 showed that performance on a sequential-matching task was viewpoint-dependent for all three types of rotation. The best face-recognition accuracy and shortest reaction time was found for roll rotations, then for yaw rotations, and finally the worst accuracy and slowest reaction time was found for pitch rotations. Directional differences in recognition were found for pitch rotations, but not for roll or yaw. Experiment 2 provided evidence that, in all three cases, viewpoint-dependent declines in recognition were primarily driven by the loss of configural information. However, it also appeared that significant featural information was lost following yaw and pitch (but not roll) rotations. Together, these findings show that unfamiliar-face recognition is viewpoint-dependent following rotation about each axis (and in each direction), and that performance is based on the availability of configural and, to a lesser extent, featural information.
我们直接比较了面部在绕偏航、俯仰和滚转轴线进行0度至75度视角旋转后的识别情况。目的是确定在绕这些轴中的每一个轴旋转后，构型信息和特征信息对面部识别的支持程度。实验1表明，在顺序匹配任务中，对于所有三种旋转类型，表现都依赖于视角。滚转旋转的面部识别准确率最高且反应时间最短，其次是偏航旋转，俯仰旋转的准确率最低且反应时间最长。俯仰旋转存在识别方向差异，但滚转或偏航旋转不存在。实验2提供的证据表明，在所有三种情况下，依赖视角的识别下降主要是由构型信息的丧失导致的。然而，似乎在偏航和俯仰（而非滚转）旋转后，大量特征信息也丧失了。这些发现共同表明，不熟悉面孔的识别在绕每个轴（以及每个方向）旋转后都依赖于视角，并且表现基于构型信息以及在较小程度上基于特征信息的可用性。
