视觉神经科学和神经网络建模的发展表明，视觉对象的形状和表面属性的处理存在不同的路径。与以前的理论建议一致，假设表格的加工只能在填充颜色等表面属性时或之后才是显性的或有意识的。结合现有的心理物理学发现，这些发展指出了无意识和有意识地处理这些属性之间的有趣区别，特别是与可区分的时间动力学有关。在无意识水平上，形式加工比表面处理进行得快，相反，在有意识水平上，形式处理比表面处理进行得慢。讨论了分离的形式和表面处理在当前和未来的心理物理和神经科学研究中的应用，特别是将皮层振荡与表面和形式特征的结合联系起来的应用，以及对于认知科学和心理和意识的哲学的应用。
Developments in visual neuroscience and neural-network modeling indicate the existence of separate pathways for the processing of form and surface attributes of a visual object. In line with prior theoretical proposals, it is assumed that the processing of form can be explicit or conscious only as or after the surface property such as color is filled in. In conjunction with extant psychophysical findings, these developments point to interesting distinctions between nonconscious and conscious processing of these attributes, specifically in relation to distinguishable temporal dynamics. At nonconscious levels form processing proceeds faster than surface processing, whereas in contrast, at conscious levels form processing proceeds slower than surface processing. I mplications of separate form and surface processing for current and future psychophysical and neuroscientific research, particularly that relating cortical oscillations to conjunctions of surface and form features, and for cognitive science and philosophy of mind and consciousness are discussed.
