Recent research suggests that repetition priming (RP) for unfamiliar faces is highly view dependent and is eliminated when the viewpoint of target faces changes between study and test. The current research examined whether increased familiarity with novel faces from a single viewpoint at study would support RP from an alternative viewpoint at test. Participants passively viewed novel face images from a single viewpoint at study (i.e., either front or three-quarters), with half of the images seen once and half seen on five occasions. During a sex classification task at test, participants were faster to respond to face images seen from the same view as that at study than they were to previously unseen distractor faces for both single exposure faces and faces seen on five occasions (i.e., standard RP). When, however, face images at test were shown from a different viewpoint from that at study, RP only occurred for faces viewed on five occasions.
最近的研究表明，对不熟悉面孔的重复启动效应（RP）高度依赖视角，当目标面孔在学习和测试之间的视角发生变化时，该效应会消失。当前的研究考察了在学习时从单一视角增加对新面孔的熟悉度是否会支持在测试时从另一个视角的重复启动效应。参与者在学习时从单一视角（即正面或四分之三侧面）被动观看新面孔图像，其中一半图像观看一次，另一半观看五次。在测试的性别分类任务中，对于单次曝光的面孔和观看五次的面孔，参与者对从与学习时相同视角看到的面孔图像的反应比对之前未见过的干扰面孔更快（即标准重复启动效应）。然而，当测试时的面孔图像从与学习时不同的视角呈现时，重复启动效应只出现在观看五次的面孔上。
