The Still-face Paradigm has been widely used for the assessment of emotion regulation in infants, as well as for the study of the mother-child relationship. Given the close bond that dogs have with humans, the purpose of this research was to evaluate, through an exploratory descriptive study, the presence of the Still-face effect in dogs. To this end, a group of Beagle dogs were exposed to three one-minute phases in which first, an unknown experimenter interacted actively and positively with each dog (Interaction). Then, suddenly, she interrupted the interaction and remained passive, with a non-expressive face and without speaking or petting the dog (Still-face). Finally, the experimenter reestablished the interaction (Reunion). Our results showed a decrease in affiliative behaviors in dogs during the Still-face phase according to changes in the human's behavior, a pattern similar to the one previously found in infants. Contrary to expectations, no stress-related behaviors were shown during that phase. A carry-over effect was also observed in the Reunion phase. This study provides information about the human-dog interaction and the effects of its disruption on dogs' behaviors.
静止面孔范式被广泛用于评估婴儿的情绪调节能力，以及研究母婴关系。鉴于狗与人类之间的密切联系，本研究旨在通过探索性描述性研究评估狗是否存在静止面孔效应。为此，一组比格犬被暴露在三个持续一分钟的阶段中，在每个阶段中，首先，一个不熟悉的实验员积极且积极地与每只狗互动（互动）。然后，她突然中断了互动，保持被动，面无表情，不说话也不抚摸狗（静止面孔）。最后，实验员重新建立了互动（团聚）。我们的研究结果表明，狗在静止面孔阶段的亲社会行为减少，这与人类行为的变化模式相似，与之前在婴儿中发现的模式相似。出乎意料的是，在那个阶段没有表现出与压力相关的行为。在团聚阶段也观察到了延续效应。这项研究提供了有关人与狗互动以及其干扰对狗行为影响的信息。
