动物的信号通常是“多分量”的(1-3)，由几个部分组成的显示器可以利用不同的感官，例如孔雀的求偶展示，它结合了活泼的动作和嘈杂、闪闪发光的火车羽毛的展示(4)。然而，多分量信令的重要性尚不清楚。作为一个典型的多组分信号系统，我们研究了有毒昆虫的命名信号，它们经常将吡嗪的气味与明显的颜色相结合，如黄色或红色(5-7)。在这里，我们证明，在鸟类的猎物选择实验中，吡嗪与红色和黄色相互作用，导致人们对这些没有气味的颜色产生强烈的厌恶。研究表明，吡嗪既不是天生厌恶的颜色，也不会引起对一种非色素性颜色--绿色的厌恶。据我们所知，这项研究提供了第一个证据，证明多成分信号的功能可能在于它们的成分相互作用所产生的隐藏心理反应。
ANIMAL signals are often 'multicomponent'(1-3), consisting of displays with several parts to allow exploitation of different senses, An example is the courtship display of the peacock, which combines dashing movements with a noisy, shimmering show of his train feathers(4). Yet the significance of multicomponent signalling is unknown. As a model multicomponent signalling system, we investigated the naming signals of toxic insects, which often combine pyrazine odours with conspicuous coloration such as yellow or red(5-7). Here we demonstrate, in prey choice experiments with birds, that pyrazine interacts with red and yellow to induce strong aversions to these aposematic colours that are not shown in the absence of the odour. Pyrazine is shown neither to be inherently aversive, nor to induce aversion to a non-aposematic colour, green. To our knowledge, this study provides the first evidence that the function of multicomponent signals can lie in hidden psychological responses produced by the interaction of their components.
