对时间动态和静态特征的同时加工和注意一直是鸟类视觉认知理论中的一个开放而重要的问题。在这里，四只鸽子(Columba Livia)学会了辨别复杂的显示器，这些显示器涉及同时可用的静态和动态特征。这些显示器由20个元素组成，这些元素由两个二进制静态视觉维度组合而成：红色与绿色元素颜色、大元素与小元素大小，以及两个二进制值动态维度、快与慢元素运动、右与上运动方向。这四个功能的一个组合在VI时间表上得到了加强。其余15种元素颜色、大小、速度和方向的组合从未得到加强。在获取过程中，所有四个维度都被同时区分。改变要素的数量表明，单个要素足以支持对所有四个方面的歧视。鸽子们一致认为，不同维度内和不同维度之间刺激的相对可识别性是一致的，运动方向的差异对所有鸟类来说都是最难的。冗余易化意味着对动态和静态特征的快速处理，也许是并行的。没有观察到动态或静态维度之间的注意权衡。这些结果与鸟类视觉的理论一致，该理论采用了不同类型信息的多个独立通道的概念。
The simultaneous processing and attention to temporally dynamic and static features remains an open and important question in theories of avian visual cognition. Here, four pigeons (Columba livia) learned to discriminate complex displays involving concurrently available static and dynamic features. These displays consisted of 20 elements built from combinations of two, binary-valued, static visual dimensions: red vs. green element color, large vs. small element size, and two binary-valued dynamic dimensions, fast vs slow element motion, right vs up motion direction. One combination of these four features was reinforced on a VI schedule. The remaining 15 combinations of element color, size, speed and direction were never reinforced. During acquisition, all four dimensions were simultaneously discriminated. Varying the number of elements revealed that a single element was sufficient to support discrimination of all four dimensions. The pigeons agreed on the relative discriminability of stimuli within and across the different dimensions, with difference in motion direction being the hardest for all birds. Redundant facilitation suggested rapid, perhaps parallel, processing of both dynamic and static features. No attentional trade-offs between dynamic or static dimensions were observed. These results agree with theories of avian vision employing the notion of multiple independent channels for different types of information.
