The face inversion effect, evidence that humans possess a specialized system for face processing, and the (3/4) view advantage, evidence that a canonical viewpoint exists from which faces may be optimally recognized, are two commonly cited findings in the face processing literature. In this paper, the interaction of these effects is examined in a sequential matching paradigm in which unfamiliar faces are combinatorially randomized in pose across two dimensions (roll and yaw). Using large numbers of poses, trials and face stimuli, two experiments were conducted in which pose was either jointly or independently randomized between intervals. Results include that performance was modulated in a continuous fashion as each dimension was manipulated, that an offset-specific (3/4) advantage exists, that both specific study and test pose affect recognition, and that, for like offset, yaw rotation is more deleterious to performance than roll rotation. Response bias effects included that matched or reflective yaw led observers to employ a more liberal criterion.
面孔倒置效应（证明人类拥有专门的面孔处理系统的证据）以及（3/4）视角优势（证明存在一个能最佳识别面孔的规范视角的证据）是面孔处理文献中两个常被引用的发现。在本文中，我们在一个序列匹配范式中研究了这些效应的相互作用，在该范式中，不熟悉的面孔在两个维度（横滚和偏航）上进行组合随机化摆放。使用大量的摆放姿势、试验和面孔刺激，我们进行了两个实验，其中姿势在不同间隔中要么联合随机化要么独立随机化。结果包括：随着每个维度的变化，表现以连续的方式受到调节；存在特定偏移的（3/4）优势；特定的学习和测试姿势都会影响识别；并且对于相同的偏移，偏航旋转比横滚旋转对表现的损害更大。反应偏差效应包括：匹配或反射性偏航会导致观察者采用更宽松的标准。
