催乳素的释放是对生理和心理压力的反应，后者涉及动物对其环境的潜在危险的解释。这种解释可能会被社会缓冲所改变，正如社会伙伴的存在所定义的那样。为了支持这一说法，我以前发现，在暴露于开放领域的同种的存在下，导致较低水平的催乳素在幼年大鼠比单独暴露于开放领域。因为同种动物的试验允许动物接触，所以身体接触可能是减少催乳素所必需的。为了验证这一假设，本研究中的幼龄雄性和雌性大鼠暴露于开放场地（1）单独，（2）与由树脂玻璃隔板隔开的同种，或（3）与没有隔板的同种。触摸是必要的，以减少压力，衡量催乳素水平。
Prolactin is released in response to physical and psychological stress, the latter of which involves an animal’s interpretation of its environment as potentially dangerous. This interpretation might be altered by social buffering, as defined by the presence of a social partner. In support of this claim, I previously found that the presence of a conspecific during exposure to the open field caused lower levels of prolactin in juvenile rats than did exposure to the open field alone. Because testing with a conspecific allowed the animals to touch, physical contact may have been necessary for the reduction of prolactin. To test this hypothesis, juvenile male and female rats in the present study were exposed to the open field (1) alone, (2) with a conspecific separated by a Plexiglas partition, or (3) with a conspecific without a partition. Touch was necessary to reduce stress as measured by prolactin levels.
