Overlearning refers to the continued training of a skill after performance improvement has
plateaued. Whether overlearning is beneficial is a question in our daily lives that has never
been clearly answered. Here we report a new important role: overlearning in humans
abruptly changes neurochemical processing, to hyperstabilize and protect trained
perceptual learning from subsequent new learning. Usually, learning immediately after
training is so unstable that it can be disrupted by subsequent new learning until after passive …
