对大规模环境的主动探索比被动观察更能学习空间布局[1-3]。但积极的探索也可能帮助我们记住场景中单个对象的外观。事实上，当我们遇到新的物体时，我们经常操纵它们，以便从各种角度看到它们。我们在这里提出的第一个证据表明，以这种方式的视觉输入的主动控制，促进以后的识别对象。在电脑屏幕上主动旋转新奇的三维物体的观察者比被动观看这些虚拟物体的完全相同的图像序列的观察者表现出更有效的视觉识别。在主动探索过程中，观察者主要关注物体的“侧面”或“正面”视图（参见[4-6]），结果表明，物体在以后的识别中的表现方式受到学习过程中是否控制视觉输入的影响。
Active exploration of large-scale environments leads to better learning of spatial layout than does passive observation [1-3]. But active exploration might also help us to remember the appearance of individual objects in a scene. In fact, when we encounter new objects, we often manipulate them so that they can be seen from a variety of perspectives. We present here the first evidence that active control of the visual input in this way facilitates later recognition of objects. Observers who actively rotated novel, three-dimensional objects on a computer screen later showed more efficient visual recognition than observers who passively viewed the exact same sequence of images of these virtual objects. During active exploration, the observers focused mainly on the 'side' or 'front' views of the objects (see also [4-6]), The results demonstrate that how an object is represented for later recognition is influenced by whether or not one controls the presentation of visual input during learning.
