认知过程中的性别差异在人类中普遍存在，并渗透到许多（如果不是大多数）认知领域。然而，在动物认知研究中，可能的性别差异仍然经常被忽视。在这里，我们提供了显着的证据，性别特异性反应的对象永久性任务在国内的狗（犬）。雌狗对一个违反预期的球的反应是显著增加的注视时间，这个球在暂时被遮挡的情况下“神奇地”改变了大小。相比之下，公犬，无论其中性状态，没有回应的大小恒定性侵犯。这些结果表明，性别差异的基本认知过程中可能会延伸到哺乳动物一般，并呼吁更多的考虑可能的性别影响时，分析和解释数据在动物认知。
Differences between sexes in cognitive processes are widespread in humans and permeate many, if not most, cognitive domains. In animal cognition research, however, possible sex differences are still often neglected. Here, we provide striking evidence for a sex-specific response in an object permanence task in domestic dogs (Canis familiaris). Female dogs responded with significantly increased looking times to a violation of expectancy-a ball 'magically' changing size while temporarily occluded. By contrast, male dogs, irrespective of their neuter status, did not respond to the size constancy violation. These results indicate that sex differences in basic cognitive processes may extend to mammals in general, and call for increased consideration of possible sex effects when analysing and interpreting data in animal cognition.
