奖励的行为功能包括诱导学习和接近行为。奖励不仅与饥饿、口渴和繁殖等植物人状态有关，还可能包括视觉刺激。本实验在实验室环境下，采用按键、触摸电脑显示器和选择行为三种操作性任务，考察了不同类型的静态和动态图片的奖赏潜力。我们发现，所有测试的视觉刺激诱导的方法在所有三个任务的行为，动作电影持续一贯较高的反应率相比，不断变化的静态图片，这是更有效的比恒定的静态图片。这些结果表明，视觉刺激可以作为动物在受控实验室环境中的操作性反应的阳性检测剂。特别是，电影中连贯的动画视觉刺激具有相当大的奖励潜力。这些观察将允许类似形式的视觉奖励用于神经生理学研究与非植物性奖励相关的机制。
The behavioral functions of rewards comprise the induction of learning and approach behavior. Rewards are not only related to vegetative states of hunger, thirst and reproduction but may also consist of visual stimuli. The present experiment tested the reward potential of different types of still and moving pictures in three operant tasks involving key press, touch of computer monitor and choice behavior in a laboratory environment. We found that all tested visual stimuli induced approach behavior in all three tasks, and that action movies sustained consistently higher rates of responding compared to changing still pictures, which were more effective than constant still pictures. These results demonstrate that visual stimuli can serve as positive reinforcers for operant reactions of animals in controlled laboratory settings. In particular, the coherently animated visual stimuli of movies have considerable reward potential. These observations would allow similar forms of visual rewards to be used for neurophysiological investigations of mechanisms related to non-vegetative rewards.
