摘要

了解同类的年龄等级对动物来说至关重要,有助于它们对社会环境做出适应性行为反应。这可能包括通过多种模态收集和整合信息。我们利用跨模态偏好观察范式,研究了狗是否拥有同种动物年龄等级的跨模态心理表征。在实验 1 中,狗会看到成犬和幼犬的图像并排投影在墙上,同时播放成犬或幼犬的声音。为了测试成犬和幼犬图像之间相对体型的影响,我们对视觉刺激采用了两种体型条件(自然体型和相同体型)。我们研究了狗对跨模态匹配刺激和不匹配刺激的观察行为。我们预测,如果狗对年龄等级有跨模态表征,那么与不匹配的图像相比,它们会对匹配的图像表现出更长时间的注意。在实验 2 中,我们在眼动追踪实验中使用了相同的范式,以进一步提高狗的注视时间的测量质量。然而,在这两项实验中,狗的注视时间并没有因为图像和发声之间的匹配或不匹配而出现显著差异。相反,我们观察到了大小效应,这表明与较小的幼犬图像相比,狗对较大的成年狗图像的注意力有所增加。因此,我们没有发现狗的年龄等级有跨模态表征的证据。尽管如此,我们在实验 2 中发现,与成犬的叫声相比,犬在听到幼犬叫声时的注视时间和瞳孔都有所增加,这表明犬在听到幼犬呜叫时表现出了更高的兴奋性。(PsycInfo Database Record (c) 2024 APA, 版权所有)。

Cross-modal perception of puppies and adult conspecifics in dogs (Canis familiaris).

Understanding conspecifics' age classes is crucial for animals, facilitating adaptive behavioral responses to their social environment. This may include gathering and integrating information through multiple modalities. Using a cross-modal preferential-looking paradigm, we investigated whether dogs possess a cross-modal mental representation of conspecific age classes. In Experiment 1, dogs were presented with images of an adult dog and a puppy projected side by side on a wall while a vocalization of either an adult dog or a puppy was played back simultaneously. To test the effect of relative body size between adult dog and puppy images, two size conditions (natural size and same size) were employed for visual stimuli. We examined dogs' looking behavior in response to cross-modally matched versus mismatched stimuli. We predicted that if dogs have cross-modal representations of age classes, they would exhibit prolonged attention toward matched images compared to mismatched ones. In Experiment 2, we administered the same paradigm within an eye-tracking experiment to further improve the measurement quality of dogs' looking times. However, dogs' looking times in either experiment did not demonstrate significant differences based on the match or mismatch between image and vocalization. Instead, we observed a size effect, indicating dogs' increased attention toward larger adult dog images compared to smaller puppy images. Consequently, we found no evidence of cross-modal representation of age class in dogs. Nonetheless, we found increased looking time and pupil size upon hearing puppy vocalizations compared to adult vocalizations in Experiment 2, suggesting that dogs exhibited heightened arousal when hearing puppy whining.
