大多数用于实验室啮齿动物的行为测试包括测量对物理新奇的行为反应。然而，实验室啮齿动物通常来自高度社会化的物种，与新的物理对象相比，新的社会刺激可能会引起不同程度的恐惧或好奇心。我们假设，行为反应会有所不同，在响应新的物理与社会线索，女性可能会表现出更多的探索社会新奇，根据先前的研究表明，女性更积极地寻求社会支持胁迫期间相比，男性。我们比较了年轻（55日龄）的Sprague-Dawley大鼠对一个充满新物体（“物理”）或一个新的同性笼中同种（“社会”）的竞技场的反应。与新的物理刺激相比，大鼠更活跃，并且花费两倍的时间与新的社会刺激接触。虽然女性比男性更活跃，但与男性相比，女性在社会竞技场中并不特别具有探索性。结果表明，一个新的社会伙伴（即使是一个笼子里的互动能力有限）激发更多的探索比新的对象为男性和女性的大鼠。
Most behavioral tests used with laboratory rodents involve measuring behavioral responses to physical novelty. However, laboratory rodents are often derived from highly social species for which novel social stimuli may induce different levels of fear or curiosity compared to novel physical objects. We hypothesized that behavioral responses will differ in response to novel physical vs. social cues, and that females may show more exploration of social novelty, based on prior studies indicating that females more actively seek social support during duress compared to males. We compared young (55-day-old) Sprague-Dawley rats’ responses to an arena filled with novel objects (“physical”) or a novel same-sex caged conspecific (“social”). Rats were more active and spent twice as much time in contact with the novel social stimulus compared to novel physical stimuli. Although females were more active than males, females were not particularly more exploratory in the social arena compared to males. The results indicate that a novel social partner (even a caged one with limited ability to interact) elicits more exploration than novel objects for both male and female rats.
