How are visual objects represented and recognized in the human brain? My research program is targeted to answer this broad question. In the last 40 years, psychophysics, electrophysiology and, more recently, neural imaging studies have deciphered many aspects of the early stages of visual processing. We now know that visual perception starts with a decomposition of images into their most basic properties such as spatial frequency and orientation. A lot less is known about the later stages of visual processing that enable recognition complex visual objects. We propose to use methodological equivalents of approaches that have been instrumental in studies of lower-level vision to examine higher-level processes involving invariant visual object recognition.

视觉对象在人脑中是如何被表征和识别的？我的研究计划旨在回答这个广泛的问题。在过去的40年里，心理物理学、电生理学以及最近的神经成像研究已经破译了视觉处理早期阶段的许多方面。我们现在知道，视觉感知开始于将图像分解为它们最基本的属性，如空间频率和方向。我们对视觉处理的后期阶段知之甚少，这些阶段使我们能够识别复杂的视觉对象。我们建议使用方法等价的方法，已在较低层次的视觉研究，以检查涉及不变的视觉对象识别的较高层次的过程。
