Self-generated stimuli often elicit reduced perceptual and neural responses relative to externally generated ones (sensory attenuation).

But behavioral findings remain inconsistent, perhaps because studies differ in the strength of the action-outcome coupling, that is, how reliably an action predicts its sensory consequence.

We compared an overlearned coupling (keypress → tone) with a novel one (saccade → tone). Keypress-generated tones were perceived as less loud than passively presented tones; saccade-generated tones, as quieter when their occurrence was more strongly expected.

Sensory attenuation thus scales with the strength of the action-outcome coupling, in line with the hybrid prediction model of Dogge et al. (2019): overlearned couplings would rely on motor-based forward models, novel ones on broader predictive mechanisms.
