Petrov, Alexander A.; Dosher, Barbara Anne; Lu, Zhong-Lin – Psychological Review, 2005
The mechanisms of perceptual learning are analyzed theoretically, probed in an orientation-discrimination experiment involving a novel nonstationary context manipulation, and instantiated in a detailed computational model. Two hypotheses are examined: modification of early cortical representations versus task-specific selective reweighting.…
