Freshly asphyxiated male or female house mice and prairie deer mice were presented to hungry male or female wild-strain house mice. Male subjects ate significantly more conspecific than contraspecific flesh, but females showed no statistically reliable preference. This sex difference, which is essentially opposite that previously reported in deer mice, is related to species-specific sex differences in aggressiveness using a response-competition model.
将刚窒息死亡的雄性或雌性家鼠和草原鹿鼠呈现给饥饿的雄性或雌性野生品系家鼠。雄性实验对象食用同种肉明显多于异种肉，但雌性未表现出统计学上可靠的偏好。这种性别差异与之前在鹿鼠中报道的情况基本相反，它与使用反应竞争模型的物种特异性攻击性行为中的性别差异有关。
