AB  - Several studies employed the repetition suppression paradigm to investigate the 
      face-specific N170 component of the event-related potential (ERP), but yielded 
      highly inconsistent results. Varying inter-stimulus intervals (ISIs) may account 
      for inconsistencies between studies. This study aimed at exploring the time 
      course of repetition suppression by systematically investigating the association 
      between ISI and ERP adaptation. Fourteen healthy subjects were investigated with 
      a passive face recognition paradigm using paired stimuli. Stimuli were presented 
      for 500ms and ISIs parametrically varied between 400 and 2000ms. N170 was 
      constructed to investigate adaptation effects on the level of perceptual face 
      processing. We found an evidence for an asymptotic decay of repetition 
      suppression over time with significant N170 adaptation effects only after the 
      shortest ISI. Our results robustly demonstrate that N170 adaptation in a paired 
      stimulus protocol critically depends on short ISIs, thereby explaining the 
      inconsistencies observed in the previous studies. For future social cognition 
      studies using neuronal adaptation to face stimuli, the current results provide a 
      well defined ISI associated with a large N170 adaptation effect.
