Two pigeons were taught to use symbols to communicate information about hidden colors to each other. When reporting red was more generously reinforced than reporting yellow or green, both birds passed through a period in which they "lied" by reporting another color as red.
两只鸽子被教会使用符号相互交流关于隐藏颜色的信息。当报告红色比报告黄色或绿色得到更慷慨的强化时，两只鸟都经历了一个时期，它们通过将另一种颜色报告为红色来“说谎”。
