In Experiment 1, subjects were trained with an orientation discrimination task at the orientation of 15° right tilted from the vertical. The training not only improved subjects' orientation discrimination performance, but also shifted their perceived vertical toward the trained orientation, which resembles a well-known visual illusion—tilt aftereffect. Interestingly, the change of perceived vertical and performance improvement had different dynamics. Subjects' performance levels were maintained at a constant level, even 2months after training. However, their perceived vertical changes reduced dramatically 1week after training. In addition, Experiment 1 showed that there was only a weak transfer of the perceived vertical change from the trained location to the untrained location. Experiment 2 demonstrated that subjects' perceived vertical was not affected by training at 75°. These results suggest that the orientation discrimination training could modify neuronal responses in human retinotopic visual areas and the development of perceptual learning is not a single neural process.
