许多视觉任务可以分解为一系列更简单的子任务。Ullman认为,这些子任务是由视觉大脑中的专门过程实现的基本操作来执行的[Ullman,S。(1984年)。视觉程序。认知(18),97-159]。根据这一假设,有有限数量的基本操作,因为它们可以顺序应用,但可能会产生大量的视觉例程。这种基本操作的示例是视觉搜索、纹理分离和轮廓分组。在这里,我们试图描绘这些基本操作是如何在视觉大脑中实现的。当图像出现时,前馈处理迅速导致分布在许多视觉区域的活动模式。此后,基本操作开始发挥作用,这些操作通过调节发射率来实现。放电频率调制实现了将神经反应分组为连贯的对象表征。此外,它们允许从一个操作员向下一个操作员传送信息,这使得操作顺序具有灵活性。我们讨论了如何基本操作提供了一个工具,将皮层生理学的心理物理学,并建议重新分类的前注意和注意的过程。
Many visual tasks can be decomposed into a sequence of simpler subtasks. Ullman suggested that such subtasks are carried out by elemental operations that are implemented by specialized processes in the visual brain [Ullman, S. (1984). Visual routines. Cognition (18), 97–159]. According to this hypothesis, there are a limited number of elemental operations that, since they can be applied sequentially, may nevertheless give rise to a large number of visual routines. Examples of such elemental operations are visual search, texture segregation and contour grouping. Here we attempt to delineate how such elemental operations are implemented in the visual brain. When an image appears, feedforward processing rapidly leads to an activity pattern that is distributed across many visual areas. Thereafter, elemental operations come into play, and these are implemented by the modulation of firing rates. Firing rate modulations effectuate grouping of neural responses into coherent object representations. Moreover, they permit transfer of information from one operator to the next, which allows flexibility in the sequencing of operations. We discuss how the elemental operations provide a tool to relate cortical physiology to psychophysics, and suggest a reclassification of pre-attentive and attentive processes.
