AB  - High perceptual load is thought to impair the early processing of task-irrelevant 
      distractors. In contrast, for emotional faces, previous studies have shown that 
      early event-related potentials (ERPs), the P1, the N170, and, albeit to a lesser 
      degree, the EPN, are relatively resistant to perceptual load manipulations. 
      However, the temporal dynamics of the interaction between load and processing of 
      emotional distractor faces have been neglected so far. In this preregistered EEG 
      study (N = 40), we investigated effects of perceptual load and different 
      interstimulus intervals (ISIs) on ERPs to fearful and neutral task-irrelevant 
      faces. We used a task with identical visual input regardless of perceptual load 
      (high vs. low), and four ISIs between task and face onset (100 ms, 300 ms, 
      600 ms, 900 ms). Results show that emotional ERP modulations depend on load 
      manipulations as well as on specific ISIs between the perceptual task and face 
      onset. Emotional P1 effects were modulated by load, irrespective of the ISI, 
      while emotional N170 and EPN effects were independent of load, but modulated by 
      the ISI. In particular, emotion effects for the EPN were only observed after a 
      prolonged period between load task and face onset (ISI900), suggesting a strong 
      vulnerability of this component to any competing task. Taken together, our 
      findings show that early ERP components for fearful expressions show dissociable 
      responses to load and timing manipulations.
