在斑胸草雀（Taeniopygia guttata）中，雌性更喜欢表现频率高的雄性。在这些实验中，测试了女性经历对这种偏好的影响。在接受三种处理之一之前和之后，雌性与一对雄性一起呈现：（1）展示率低的雄性，（2）展示率高的雄性，或（3）没有新的雄性。女性对第一对中表现出更多的男性的偏好受到上述处理的影响。如果雌性接触过展示率低的雄性，则她们对这只雄性的相对偏好会增加；如果接触过展示率高的雄性，她们的偏好会降低；如果没有接触新的雄性，她们的偏好不会改变。为了测试偏好的变化是否与性相关，在干预治疗之前和之后对雌性重复了该实验。这些治疗对女性对女性配对的偏好没有影响。讨论了这些结果对性选择模型和择偶策略的影响。
In zebra finches, Taeniopygia guttata, females prefer males that display at a high rate. In these experiments the effect of a female's experience on this preference was tested. Females were presented with a pair of males before and after being exposed to one of three treatments: (1) males with a low display rate, (2) males with a high display rate, or (3) no new males. Female preference for the male of the initial pair that displayed more was affected by the above treatments. Females increased their relative preference for this male if they had been exposed to males with a low display rate, decreased their preference if exposed to males with a high display rate, and did not change their preference if exposed to no new males. To test whether the changes in preference were sexual, the experiment was repeated with female pairs before and after the intervening treatments. There was no effect of the treatments on female preference for female pairs. The implications of these results for models of sexual selection and mate-choice strategies are discussed.
