Multifaceted Study on Flexibility of Adult Visual Perception

首先，本研究证明了这一现象，即知觉的面孔形状是由看到其他面孔提前影响。此外，这种“后效”对于面部和非面部对象是不同的。第二，多次看到相同的面孔会增加他们的吸引力。这种现象被称为“单纯暴露效应”。本研究发现，单纯曝光效应可能会推广到以前看不见的脸，当他们是以前见过的脸的平均值。第三，本研究表明，知觉的长度或大小的物体是由其本身的形状和相邻的轮廓。因此，它表明，人类视觉系统适应灵活地不断变化的环境，通过调整视觉感知使用刺激，无论是时间上或空间上邻近的焦点刺激。

First, the present study demonstrated the phenomenon that perceived shape of a face is influenced by seeing other faces in advance. Moreover, this "aftereffect" differs for faces and non-face objects. Second, it is well established that seeing the same faces several times increases their attractiveness. This phenomenon is called "mere exposure effect". The present study discovered that the mere exposure effect may generalize to previously unseen faces when they are averages of previously seen faces. Third, the present study showed that perceived length or size of an object is affected by its own shape and adjacent contours. Thus, it is shown that the human visual system adapts flexibly to the ever-changing environment by adjusting visual perception using stimuli which are either temporally or spatially adjacent to the focal stimuli.
