10只不同品种和年龄的家犬（Canis familiaris）暴露于2种不同的社会线索，表明隐藏食物的位置，每种线索由人类线人和同种线人提供（共4种不同的社会线索）。对于局部增强提示，被试接近食物隐藏的位置，然后呆在它旁边。对于凝视和点提示，被试站在两个隐藏位置之间的等距位置，身体朝向并凝视隐藏食物的位置（人类被试也指向）。10名受试者中有8名，包括一名6个月大的少年，在2个或更多线索的情况下高于机会。结果进行了讨论的系统发育和个体发育的过程中，狗来使用社会线索来定位食物。
Ten domestic dogs (Canis familiaris) of different breeds and ages were exposed to 2 different social cues indicating the location of hidden food, each provided by both a human informant and a conspecific informant (for a total of 4 different social cues). For the local enhancement cue, the informant approached the location where food was hidden and then stayed beside it. For the gaze and point cue, the informant stood equidistant between 2 hiding locations and bodily oriented and gazed toward the 1 in which food was hidden (the human informant also pointed). Eight of the 10 subjects, including the one 6-month-old juvenile, were above chance with 2 or more cues. Results are discussed in terms of the phylogenetic and ontogenetic processes by means of which dogs come to use social cues to locate food.
