使用红外热像系统，我们已经证明，正如之前报道的那样，猕猴鼻部区域的温度在负面情绪状态下会降低，比如面对威胁的人时。在这项研究中，我们探索了测量鼻部皮肤温度在猴子情绪研究中的用处，这些情绪表现为相同的情绪行为和表情。我们测量了恒河猴(Macaca Mulatto)对视频片段的鼻部皮肤温度，所有视频片段都显示了猴子：一个愤怒的个体(实验1)，三种不同的情感表达(实验2)，只有代表威胁的脸或声音(实验3)。我们发现，即使当刺激是带有数字化声音的20英寸图像时，鼻部皮肤温度也会显著降低，这与许多关于动物情绪的心理学或神经生理学研究中使用的类似。此外，特定物种的攻击性威胁总是会引起鼻部皮肤温度和皮肤电导反应的下降；然而，尖叫或咕噜声不会引起这种反应。与单独感知面部表情或发声相比，同时感知面部表情和发声导致鼻部皮肤温度下降更显著。综上所述，这些数据表明，鼻部皮肤温度的降低应该被添加到动物情绪状态的指标列表中。(C)2010 Elsevier Inc.保留所有权利。
Using an infrared thermographic system, we have demonstrated, as previously reported, that temperatures in the nasal region of macaque monkeys decrease during negative emotional states, such as when facing a threatening person. In this study, we explored the usefulness of measuring nasal skin temperatures in studies of monkey emotions as manifested by conspecific emotional behaviors and expressions. We measured nasal skin temperatures of rhesus monkeys (Macaca mulatto) in response to video clips, all showing monkeys: a raging individual (Experiment 1), three distinct emotional expressions (Experiment 2), and only faces or voices representing a threat (Experiment 3). We found that nasal skin temperatures significantly decreased in response to a threatening stimulus, even when the stimulus was a 20 image with digitized sound, similar to those used in many psychological or neurophysiological studies on animal emotion. Moreover, species-specific aggressive threats invariably elicited a decrease in nasal skin temperatures and skin conductance responses; however, screams or coos did not elicit this response. Simultaneous perception of both facial expressions and vocalizations induced a more prominent decrease in nasal skin temperatures than did the perception of facial expressions or vocalizations alone. Taken together, these data suggest that decreased nasal skin temperatures should be added to the list of indicators of emotional states in animals. (C) 2010 Elsevier Inc. All rights reserved.
