当我们在世界中移动时,关于物体的信息会移动到不同的空间频率。因此,视觉系统如何成功地整合这些变化中的信息,形成一个连贯的感知,是一个重要的开放问题。在这里,我们调查这样的整合使用混合的面孔,其中包含不同的图像在低和高的空间频率。观察者判断一个混合体与它的每一个组成图像的相似程度,同时走向或远离它,或者让刺激朝向或远离它们。我们发现,当刺激接近时,观察者的行为就好像他们在每个时刻都在空间频率上分别进行整合。然而,当刺激消退时,观察者表现出感知滞后效应,抓住在静态刺激条件下无法感知的细节。因此,观察者似乎通过在丢失信息时坚持他们以前的解释,但在获得新信息时不断重新解释他们的输入来做出最佳推断。
As we move through the world, information about objects moves to different spatial frequencies. How the visual system successfully integrates information across these changes to form a coherent percept is thus an important open question. Here we investigate such integration using hybrid faces, which contain different images in low and high spatial frequencies. Observers judged how similar a hybrid was to each of its component images while walking toward or away from it or having the stimulus moved toward or away from them. We find that when the stimulus is approaching, observers act as if they are integrating across spatial frequency separately at each moment. However, when the stimulus is receding, observers show a perceptual hysteresis effect, holding on to details that are imperceptible in a static stimulus condition. Thus, observers appear to make optimal inferences by sticking with their previous interpretation when losing information but constantly reinterpreting their input when gaining new information.
