虽然我们对成年狗认知的理解在过去二十年中有了很大的发展，但对狗认知的个体发生却知之甚少。为了评估狗的认知特征的发展和纵向稳定性，我们在两个时间点对160只候选辅助犬进行了一系列任务。这些任务旨在测量认知的各个方面，从执行功能（例如，抑制控制，逆转学习，记忆）到感官辨别（例如，视觉，听觉，嗅觉）到与人类的社会互动。实验对象首先作为8到10周大的小狗参加，然后在大约21个月大的时候再次接受同样的任务测试。除了少数例外，任务表现随着年龄的增长而提高，在执行功能和社会注视方面观察到的影响最大。结果还表明，个体差异是早期出现并持续存在的；例如，社会对人类的关注、人类交流信号的使用、对问题的独立坚持、气味辨别和抑制控制在两个时间点之间都表现出中等水平的秩序稳定性。使用多元回归，我们发现年轻人在许多认知任务上的表现可以从早期发展中收集的一组认知测量来预测。我们的研究结果有助于了解狗在早期发育过程中的认知变化，以及个体差异的起源和发展稳定性。
While our understanding of adult dog cognition has grown considerably over the past twenty years, relatively little is known about the ontogeny of dog cognition. To assess the development and longitudinal stability of cognitive traits in dogs, we administered a battery of tasks to 160 candidate assistance dogs at two timepoints. The tasks were designed to measure diverse aspects of cognition, ranging from executive function (e.g., inhibitory control, reversal learning, memory) to sensory discrimination (e.g., vision, audition, olfaction) to social interaction with humans. Subjects first participated as 8-to-10-week old puppies, and then were retested on the same tasks at approximately 21 months of age. With few exceptions, task performance improved with age, with the largest effects observed for measures of executive function and social gaze. Results also indicated that individual differences were both early emerging and enduring; for example, social attention to humans, use of human communicative signals, independent persistence at a problem, odor discrimination, and inhibitory control all exhibited moderate levels of rank-order stability between the two timepoints. Using multiple regression, we found that young adult performance on many cognitive tasks could be predicted from a set of cognitive measures collected in early development. Our findings contribute to knowledge about changes in dog cognition across early development as well as the origins and developmental stability of individual differences.
