This study compared 3- to 4-month-olds' recognition of previously unfamiliar faces learned in a moving or a static condition. Infants in the moving condition showed successful recognition with only 30 s familiarization, even when different images of a face were used in the familiarization and test phase (Experiment 1). In contrast, infants in the static condition showed successful recognition only when the familiarization duration was lengthened to 90 s and when the same image was used between the familiarization and test phase (Experiments 2 and 3). Furthermore, presentation of multiple static images of a face did not yield the same level of performance as the moving condition (Experiment 4). These results suggest that facial motion promotes young infants' recognition of unfamiliar faces.
本研究比较了3至4个月大婴儿对在动态或静态条件下学习的先前不熟悉面孔的识别能力。处于动态条件下的婴儿即使在熟悉阶段和测试阶段使用不同的面部图像，仅通过30秒的熟悉就能成功识别（实验1）。相比之下，处于静态条件下的婴儿只有在将熟悉时间延长至90秒且在熟悉阶段和测试阶段使用相同图像时才会成功识别（实验2和3）。此外，展示多张面部静态图像并没有产生与动态条件相同水平的表现（实验4）。这些结果表明，面部运动促进了婴儿对不熟悉面孔的识别。
