Mice must perceive and interpret the signals they are presented with to evaluate potential mates, and should show a preference for high quality conspecifics. The present experiment was designed to investigate preference for acoustic, olfactory, and acoustic + olfactory signals in laboratory mice. Eighteen female CBA/CaJ mice, socially housed or isolated, were tested to evaluate preference for signals produced by males. Social experience influenced female preference for male USV playback and soiled bedding. Female mice who had experience with males showed a stronger preference for olfactory signals, whereas female mice with experience only with other females preferred USV playback. Isolated mice showed a greater preference for signals of different modalities presented together than socially experienced mice. This preference may have occurred because of increased motivation to make social contact. The findings of this experiment illustrate that social experience could play a role in mate choice.
小鼠必须感知并解读所呈现的信号以评估潜在配偶，并且应该对高质量的同种个体表现出偏好。本实验旨在研究实验室小鼠对声学、嗅觉以及声学+嗅觉信号的偏好。对18只群居或独居的雌性CBA/CaJ小鼠进行测试，以评估它们对雄性产生的信号的偏好。社交经历影响了雌性对雄性超声波发声回放和脏垫料的偏好。有与雄性接触经历的雌性小鼠对嗅觉信号表现出更强的偏好，而仅与其他雌性有接触经历的雌性小鼠则更喜欢超声波发声回放。与有社交经历的小鼠相比，独居小鼠对同时呈现的不同模态信号表现出更大的偏好。这种偏好可能是由于建立社交联系的动机增强所致。本实验的结果表明，社交经历可能在配偶选择中发挥作用。
