The regularities of the world render an intricate interplay between past and present. Even across independent trials, current-trial perception can be automatically shifted by preceding namely “serial bias.” Meanwhile, neural implementation spontaneous shift present that operates on multiple features remains unknown. In two auditory categorization experiments with human electrophysiological recordings, we demonstrate serial bias arises from co-occurrence past-trial reactivation encoding features. meeting shifts representation modulates behavior. Critically, (i.e., pitch, category choice, motor response) keep their respective identities in memory are only reactivated corresponding current trial, giving rise to dissociated feature-specific biases. automatic might constitute a fundamental mechanism for adaptive past-to-present generalizations over
