Multifaceted Study on Flexibility of Adult Visual Perception

首先，本研究证明了一种现象，即预先看到其他面孔会影响对脸型的感知。此外，这种“后效”对于人脸和非人脸物体是不同的。第二，众所周知，几次看到同一张脸会增加他们的吸引力。这种现象被称为“单纯暴露效应”。目前的研究发现，单纯的暴露效应可以推广到以前未见过的面孔，当它们是以前见过的面孔的平均值时。第三，本研究表明，感知物体的长度或大小受到其自身形状和相邻轮廓的影响。因此，研究表明，人类视觉系统通过使用与焦点刺激在时间或空间上相邻的刺激来调节视觉感知，从而灵活地适应不断变化的环境。

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.
