All in the timing: Priming, repetition suppression, and synchrony

Abstract The terms "priming" and "repetition suppression" are commonly used to refer to phenomena occurring on time scales that can differ by several orders of magnitude, ranging from seconds to days or even years. The models discussed by Gotts et al. provide a thought-provoking theoretical framework for relating neuronal and behavioral plasticity. I argue that whereas both the sharpening and the Bayesian models may mediate the gradual acquisition of perceptual expertise, they are unlikely to account for more rapid behavioral changes. The synchrony model, however, could potentially operate within the timing constraints imposed by the fastest forms of repetition priming.
