Inhibition of return is the inhibitory tagging of recently attended locations or objects. It was previously suggested that inhibition of return is a foraging facilitator in visual search. Inhibition of return was first discovered in humans and was demonstrated also in monkeys, yet it has never been demonstrated in non-primates. Here we report the presence of inhibition of return in the archer fish, which shoots down prey on overhanging vegetation, using squirts of water spouted from its mouth. Moreover, we find similar attentional effects for fish as for human participants. Our results show that the generation of inhibition of return does not require a fully developed cortex and strengthen the view that inhibition of return functions as a foraging facilitator.
返回抑制是对最近被注意到的位置或物体的抑制标记。此前有研究表明，返回抑制是视觉搜索中的一种觅食促进剂。返回抑制首先在人类中被发现，并在猴子中也得到了证明，但从未在非灵长类动物中得到证明。在这里，我们报告了弓鱼的返回抑制的存在，弓鱼通过从嘴里喷出的水射下来自悬垂植物上的猎物。此外，我们发现鱼类和人类参与者的注意力效应相似。我们的研究结果表明，返回抑制的产生并不需要一个完全发育的大脑皮层，并且加强了返回抑制作为一种觅食促进剂的作用的观点。
