Gerganov, A., Grinberg, M., & Goldstone, R. L. (2009).  Partial position transfer in categorical perception learning Proceedings of the Thirty-First Annual Conference of the Cognitive Science Society, 1828-1833. Amsterdam, Netherlands: Cognitive Science Society.

Two experiments are reported. The first shows incomplete transfer of explicit categorical learning at a distance of 4.5 degrees of visual angle and the second is a control experiment with a non-learning task. The results suggest that some early visual plasticity takes place even in a simple, explicit categorical learning task. We claim that perceptual learning is a much more common phenomenon than believed before and that it plays an important role in everyday tasks including higher-level learning.
