使用约375只雄性Long-Evans大鼠进行了6项实验。雄性大鼠杀死和吃掉幼鼠的概率与幼鼠的年龄和幼鼠先前接触的数量呈负相关。还研究了（a）饥饿和随后的食物饱食对杀死新生大鼠幼仔的影响，（B）杀死新生大鼠幼仔的经验推广到杀死断奶大鼠和小鼠，（c）新生大鼠幼仔或断奶大鼠的非杀死经验在降低杀死新生大鼠幼仔概率方面的影响，以及（d）当以小鼠幼崽为刺激物时，这些变量的影响。数据表明，（a）新生幼崽，同种或非同种，被杀害，因为他们被视为食物，而不是因为他们触发了攻击性反应系统，（B）老年幼崽没有触发攻击性反应系统，（c）种属特异性特征的大鼠幼崽触发了母源性反应系统的雄性大鼠，随后在大鼠幼崽杀害的发生率下降。(36参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Conducted 6 experiments, using approximately 375 male Long-Evans rats. The probability that male rats would kill and eat rat pups was inversely related both to age of the pup and to the amount of prior exposure to pups. Also studied were (a) the effects of hunger and subsequent food satiation on killing of neonatal rat pups,(b) the generalization of experience in killing neonatal rat pups to the killing of weanling rats and of mice,(c) the effect of nonkilling experiences with either neonatal rat pups or with weanling rats in reducing the probability of killing neonatal rat pups, and (d) the effects of these variables when mouse pups were the stimuli. The data suggest that (a) neonatal pups, conspecific or not, were killed because they were perceived as food and not because they triggered aggressive response systems,(b) older pups did trigger aggressive response systems, and (c) species-specific characteristics of rat pups triggered maternal response systems in the male rat with a subsequent decrease in the incidence of rat pup killing.(36 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
