Generation of visual habit after long-term learning. A Free-viewing condition. In this condition, there are no instructions and no rewards, allowing human subjects to move their eyes toward presented objects automatically. The white line indicates an eye trace of the human subject. B Visual habit: automatic eye movement based on previously learned object values. After long-term learning of object-reward associations and more than 3 days of retention, the eye gazes of human subjects were biased toward previously learned good objects, and the subjects’ gazes occurred without intention or awareness. White lines indicate eye traces of human subjects. Dotted circles indicate the learned values of fractal objects. C Memory-guided automatic behavior: habit. Information from the sensory inputs can be sent directly to the motor output structures, generating automatic behavior. Learning changes the brain to remember previous experiences and guide automatic behavior. For example, after long-term learning of object and reward associations, the learned value memory guides automatic behavior for maximizing the reward acquisition
