产后攻击的时间进程进行了检查在产Long-Evans大鼠（N= 77）。将单独圈养的哺乳期雌性动物（每种条件n= 7）随机分配至11种条件之一（试验日），每例受试者在产后第0天（分娩日）至第20天之间接受一次试验。侵略的持续时间是最高的，攻击的潜伏期是最短的第0天，所有的母鼠攻击一个陌生的入侵男性在10分钟的测试。参与攻击的母鼠比例在哺乳期第一周结束时仍然很高，但在产后第三周急剧下降。研究结果表明，母亲攻击的可能性和强度与分娩后进行测试的时间密切相关。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
The time course of postpartum aggression was examined in primiparous Long-Evans rats (N= 77). Individually housed lactating females (n= 7 per condition) were randomly assigned to 1 of 11 conditions (day of testing), with each subject tested once between Day 0 (the day of parturition) through Day 20 postpartum. Duration of aggression was highest and latency to attack was shortest on Day 0, with all dams attacking an unfamiliar intruding male during 10-min tests. The proportion of dams engaging in attack remained high through the end of the first week of lactation, but decreased sharply during the third week postpartum. The findings indicate that the probability and intensity of maternal aggression is closely associated with the time since parturition at which tests are given.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
