| Research Abstract |
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.
