Produced by stimuli you"ve encountered in the past. Repetition priming priming produced by a prior encounter with the stimulus. You deliberately prime detectors for inputs you think are upcoming. Ex. participants are asked to decide if letters are the same or different (aa or ab) Neutral condition warning signal = + for aa. Notified participants that stimuli were about to arrive but no other info. Primed condition warning signal = g for gg. Warning signal primes the participant for stimuli.

Ex. warning = a 20% chance that the upcoming pair would contain a.
