The authors examined how a conditioned stimulus (CS) that included species-typical cues affected the acquisition and extinction of conditioned sexual responses in male quail (Coturnix japonica). Some subjects were conditioned with a CS that supported sexual responses and included a taxidermic head of a female quail. Others were conditioned with a similar CS that lacked species-typical cues. Pairing the CSs with access to live females increased CS-directed behavior, with the head CS eliciting significantly more responding than the no-head CS. Responding to the head CS persisted during the 42-day, 126-trial extinction phase; responses to the no-head CS extinguished. Responding declined when the cues were removed or the subjects were sexually satiated. Possible functions and mechanisms of these effects are discussed.
作者研究了包含物种典型线索的条件刺激（CS）如何影响雄性鹌鹑（日本鹌鹑）条件性性行为反应的习得和消退。一些实验对象接受了能引发性行为反应且包含雌性鹌鹑标本头部的条件刺激。另一些则接受了类似但缺乏物种典型线索的条件刺激。将条件刺激与接触活体雌性配对增加了指向条件刺激的行为，有头部标本的条件刺激引发的反应明显多于无头部标本的条件刺激。在为期42天、共126次试验的消退阶段，对有头部标本的条件刺激的反应持续存在；对无头部标本的条件刺激的反应则消退了。当线索被移除或实验对象性满足时，反应减少。文中讨论了这些效应可能的功能和机制。
