Six adult female rhesus monkeys (Macaca mulatta) performed food-reinforced button presses in a compound stimulus discrimination paradigm. Three subjects were trained on a compound stimulus consisting of a color motion picture of an adult male rhesus superimposed over a homogeneous blue field of color. A second group of three subjects was trained on a compound consisting of a color slide depicting an adult male rhesus and the blue field. Subsequent testing of relative stimulus control exerted by either compounds, conspecific stimuli (movie-slide) or blue field alone was carried out. Results indicated that for the movie group, stimulus control was attenuated when either the conspecific stimulus or blue field was presented as a single S+ stimulus compared to tests using the compound stimulus as S+. Subjects in the movie group shared attention to both constituent elements of the compound. Statistically significant differences in stimulus control between compound, conspecific stimulus, and blue field were not found for the slide group. Superior control by the compound movie-blue field was explained as the result of increased visual salience of an altered (blue) conspecific image.
六只成年雌性恒河猴（猕猴）在复合刺激辨别范式中进行食物强化的按键操作。三只受试动物接受由成年雄性恒河猴的彩色电影叠加在均匀蓝色背景上组成的复合刺激训练。另一组三只受试动物接受由描绘成年雄性恒河猴的彩色幻灯片和蓝色背景组成的复合刺激训练。随后对两种复合刺激、同种刺激（电影 - 幻灯片）或单独的蓝色背景所施加的相对刺激控制进行了测试。结果表明，对于电影组，与使用复合刺激作为阳性刺激（S +）的测试相比，当同种刺激或蓝色背景作为单一阳性刺激呈现时，刺激控制减弱。电影组的受试动物对复合刺激的两个组成元素都给予了关注。幻灯片组在复合刺激、同种刺激和蓝色背景之间的刺激控制上未发现统计学上的显著差异。复合电影 - 蓝色背景的优越控制被解释为改变后的（蓝色）同种图像视觉显著性增加的结果。
