We measured infants' recognition of familiar and unfamiliar 3-D objects and their 2-D representations using event-related potentials (ERPs). Infants differentiated familiar from unfamiliar objects when viewing them in both two and three dimensions. However, differentiation between the familiar and novel objects occurred more quickly when infants viewed the object in 3-D than when they viewed 2-D representations. The results are discussed with respect to infants' recognition abilities and their understanding of real objects and representations. This is the first study using 3-D objects in conjunction with ERPs in infants, and it introduces an interesting new methodology for assessing infants' electrophysiological responses to real objects.
我们使用事件相关电位（ERP）测量了婴儿对熟悉和不熟悉的三维物体及其二维表征的识别。婴儿在二维和三维视角下观察物体时，能够区分熟悉和不熟悉的物体。然而，当婴儿以三维视角观察物体时，对熟悉和新奇物体的区分比以二维视角观察时更快。我们结合婴儿的识别能力以及他们对真实物体和表征的理解对结果进行了讨论。这是第一项将三维物体与婴儿ERP相结合的研究，它引入了一种有趣的新方法来评估婴儿对真实物体的电生理反应。
