人类学习的研究是复杂的，因为在进行任何行为任务时都涉及无数的处理元素。在视知觉学习的情况下，一直有重大的争议，关于任务过程，指导这种学习的形成，但是，有一个发展中的共识，自上而下，任务相关的因素，需要这样的学习发生。在这里，我们通过使用一种新颖的程序来挑战这一想法，在这种程序中，被剥夺食物和水的人类参与者被动地观看视觉刺激，同时偶尔接受水滴作为奖励。视觉取向刺激，这是暂时配对的液体奖励，被视为单眼和呈现察觉到的连续闪烁的轮廓丰富的图案，以另一只眼睛。结果表明，视觉学习可以形成在人类成年人通过刺激奖励配对的情况下的任务，没有意识到的刺激或奖励的偶然性。
The study of human learning is complicated by the myriad of processing elements involved in conducting any behavioural task. In the case of visual perceptual learning there has been significant controversy regarding the task-processes that guide the formation of this learning, however, there is a developing consensus that top-down, task-related factors, are required for such learning to take place. Here we challenge this idea by use of a novel procedure in which human participants, who were deprived of food and water, passively viewed visual stimuli while receiving occasional drops of water as rewards. Visual orientation stimuli, which were temporally paired with the liquid-rewards, were viewed monocularly and rendered imperceptible by continuously flashing contour rich patterns to the other eye. Results show that visual learning can be formed in human adults through stimulus-reward pairing in the absence of a task and without awareness of the stimulus presentation or reward contingencies.
