The attenuation of neural responses to repeated stimuli (response attenuation) is often attributed to either adaptation or predictive suppression. While the two mechanisms differ dramatically in their theoretical underpinnings and computational complexity, they have been difficult to separate experimentally, because they make rather similar prediction in many commonly used paradigms. To that aim we developed a new experimental paradigm that leverages the time-course of response attenuation to arbitrate between the two theories. If response attenuation is mediated by adaptation, we expect the s
