社会接触促进健康和幸福感的增强，这可能是面对各种生活压力时情绪反应的社会调节的一个功能。在这项功能性磁共振成像（fMRI）研究中，16名已婚妇女在握住丈夫的手、一名匿名男性实验者的手或根本没有手的情况下受到电击的威胁。结果表明，当女性握住丈夫的手时，支持情绪和行为威胁反应的神经系统的激活普遍减弱。当他们握着陌生人的手时，这些系统的激活衰减更为有限。最引人注目的是，配偶牵手对神经威胁反应的影响随着婚姻质量的变化而变化，婚姻质量越高，在配偶牵手时，右前额叶、上级额回和下丘脑中与威胁相关的神经激活越少，但与陌生人牵手无关。
Social contact promotes enhanced health and well-being, likely as a function of the social regulation of emotional responding in the face of various life stressors. For this functional magnetic resonance imaging (fMRI) study, 16 married women were subjected to the threat of electric shock while holding their husband's hand, the hand of an anonymous male experimenter, or no hand at all. Results indicated a pervasive attenuation of activation in the neural systems supporting emotional and behavioral threat responses when the women held their husband's hand. A more limited attenuation of activation in these systems occurred when they held the hand of a stranger. Most strikingly, the effects of spousal hand-holding on neural threat responses varied as a function of marital quality, with higher marital quality predicting less threat-related neural activation in the right anterior insula, superior frontal gyrus, and hypothalamus during spousal, but not stranger, hand-holding.
