To examine left-to-right tympanic membrane temperature asymmetries and their possible association with biobehavioral stress responses in rhesus macaques and children.
Infrared tympanic membrane thermometry was completed bilaterally in 19 two-year-old rhesus macaques and 18 eight-year-old children in a cross-sectional, laboratory-based study. Unidirectional temperature gradients were calculated as the mean of two left-sided measurements minus the mean of two right-sided measurements. Biobehavioral stress responses were assessed in monkeys as agitated motor activity and adrenocortical activation after separation from the social group, and in children as parent-reported resilience to psychological stress and child behavior problems.
Significant asymmetry was detected in tympanic membrane temperatures in both monkey and child samples, with left-sided temperatures measuring slightly but significantly higher than those from the right tympanic membrane. Higher-magnitude left-to-right temperature gradients were associated with stress-related locomotion in macaques and with lower resilience and more behavior problems in children.
There are small but reliable asymmetries in the tympanic membrane temperatures of young human and nonhuman primates. Tympanic membrane temperature gradients reflect important individual differences in biologically derived responses to psychological stressors.
研究恒河猴和儿童左右鼓膜温度的不对称性及其与生物行为应激反应的可能关联。
在一项基于实验室的横断面研究中，对19只两岁恒河猴和18名八岁儿童双侧进行红外鼓膜测温。单向温度梯度计算为两次左侧测量的平均值减去两次右侧测量的平均值。在猴子中，生物行为应激反应通过与社会群体分离后的激动运动活动和肾上腺皮质激活来评估；在儿童中，通过父母报告的对心理应激的恢复力和儿童行为问题来评估。
在猴子和儿童样本中均检测到鼓膜温度存在显著不对称，左侧温度略高于右侧鼓膜温度，但差异显著。较大幅度的左右温度梯度与猕猴的应激相关运动以及儿童较低的恢复力和更多行为问题相关。
幼年人类和非人类灵长类动物的鼓膜温度存在微小但可靠的不对称性。鼓膜温度梯度反映了对心理应激源的生物学衍生反应中的重要个体差异。
