脑的偏侧化在脊椎动物中很常见。然而，尽管它对高阶认知功能有影响，但几乎没有经验证据表明它可能对大脑的功能有任何好处。在这里，我们表明，在国内小鸡（原鸡），大脑侧化与增强能力，同时执行两项任务：寻找食物和警惕捕食者。这一发现表明，大脑侧化可以提高大脑在需要同时但不同地使用两个半球的认知任务中的效率。
Brain lateralization is common among vertebrates. However, despite its implications for higher-order cognitive functions, almost no empirical evidence has been provided to show that it may confer any advantage to the functioning of the brain. Here, we show in the domestic chick (Gallus gallus domesticus) that cerebral lateralization is associated with an enhanced ability to perform two tasks simultaneously: finding food and being vigilant for predators. This finding suggests that cerebral lateralization enhances brain efficiency in cognitive tasks that demand the simultaneous but different use of both hemispheres.
