两项研究对 29 只野生大鼠、15 只 Long-Evans 实验室大鼠和 3 组野生老鼠的 11 只第一代后代进行了检查，检查了野生大鼠在各种情况下的防御能力，并将这些行为与相同条件下的家养大鼠进行了比较。对野鼠对不可避免的接近威胁刺激（实验者）的防御行为的分析表明，对远处刺激的冻结模式，让位于在较短防御距离内发声、跳跃和跳跃攻击。在可逃脱和不可避免的情况下，对野生捕获和实验室饲养的野生老鼠对各种威胁刺激的防御反应进行比较表明，这两种野生品系与实验室老鼠相似，并且始终比实验室老鼠对人类和同种威胁刺激具有更强的防御能力。结果表明，老鼠的防御行为在驯化过程中大幅减少，其中相对较小的减少归因于标准实验室条件下的饲养。（29 参考）（PsycINFO 数据库记录 (c) 2016 APA，保留所有权利）
Examined in 2 studies, with 29 wild rats, 15 Long-Evans laboratory rats, and 11 1st-generation offspring from 3 sets of wild-trapped parents, the defensive repertoire of wild rats in a variety of situations and compared these behaviors with those of domestic rats under identical conditions. Analysis of the defensive behaviors of wild rats to an inescapable approaching threat stimulus (the experimenter) indicated a pattern of freezing to distant stimuli, giving way to vocalization, jumps, and jump attacks at shorter defensive distances. Comparisons of the defensive reactions of wild-trapped and laboratory-bred wild rats to a variety of threatening stimuli, in escapable and inescapable situations, indicated that the 2 wild strains were similar and consistently more defensive than laboratory rats to both human and conspecific threat stimuli. Results suggest that the defensive behaviors of rats have been substantially reduced during the process of domestication, with relatively little of this reduction being attributable to housing in standard laboratory conditions.(29 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
