Overview of main event-related potentials (ERP) from studies in the current review.

Neurocognitive domain Prominent components Description Proposed functional significance Relevant reference Example of studies in the current review
Sensory processing P50 Positive-going wave over fronto-temporal electrodes peaking at 40-75 ms poststimulus Attenuation of this component indexes sensory gating (the ability to filter out redundant sensory information) (Potter et al., 2006) (Magnée et al., 2009)
N1 (N100) Negative-going wave over frontocentral electrodes peaking at 80-120 ms poststimulus Sensory processing of unexpected (auditory) stimulus (Rosburg et al., 2008) (Gonen-Yaacovi et al., 2016; Sable et al., 2013)
P1 (P100) Positive-going wave over lateral occipital electrodes peaking at 80-130 ms poststimulus Sensory processing of stimulus in the contralateral visual field (Hillyard and Anllo-Vento, 1998) (Gonen-Yaacovi et al., 2016; Sable et al., 2013)
N170 Negative-going wave over posterior electrodes peaking around 130-200 ms poststimulus (face vs non-face) Structural encoding of faces (Feuerriegel et al., 2015) (O’Connor et al., 2005; Stavropoulos et al., 2016)
Early posterior negativity (EPN) Negative-going wave peaking at 150–300 ms poststimulus Selective visual attention toward emotional stimuli (Citron, 2012) (Faja et al., 2016)
Mismatch negativity (MMN) Negative-going wave peaking at 150-250 ms poststimulus Detection of infrequent and odd deviant stimulus in a repetitive sequence of auditory or visual stimuli (Garrido et al., 2009) (Fan and Cheng, 2014)



Stimulus evaluation N2 Negative-going wave peaking at 200-350 ms poststimulus Detection of mismatch and/or inhibition of competing response (Folstein and Van Petten, 2008) (Fisher et al., 2011; Groom et al., 2008)
N250 Negative-going wave over inferior temporal electrodes around 250 ms poststimulus when comparing familiar vs unfamiliar faces Storage of face representation in long-term memory (Eimer and Holmes, 2007) (Webb et al., 2010)
P2 Positive-going wave peaking at 100-250 ms poststimulus Sensitivity to various stimulus features (Crowley and Colrain, 2004) (Chien et al., 2017; Megnin et al., 2012)
P3a (novelty P3) Positive-going wave over frontocentral electrodes peaking at 250-280 ms poststimulus Novelty processing and involuntary orienting of attention (Polich, 2007) (Sokhadze et al., 2009b)
P3b (classic P3) Positive-going wave over parietal electrodes peaking at 250-500 ms poststimulus Attentional engagement and stimulus evaluation/decision-making (Polich, 2007) (Iacono et al., 2002; Rommel et al., 2017)
N3 (slow wave or late posterior negativity (LPN)) Negative-going wave peaking at 500-650 ms poststimulus over posterior electrodes Enhanced attention to stimulus, particularly the nonautomatic, controlled part of the stimulus processing (Johansson and Mecklinger, 2003) (Raz and Dan, 2015b)
N400 Negative-going wave over centropariental electrodes peaking at 250-500 ms poststimulus Processing of semantic information (Kutas and Federmeier, 2011) (Gold et al., 2010; Kulakova and Nieuwland, 2016)
Response preparation CNV Negative-going wave rising around 260-470 ms after a warning stimulus Response and motor preparation to upcoming stimulus (Mento, 2013) (Boecker et al., 2014; Cheung et al., 2016)
Lateralised readiness potential (LRP) Negative-going wave over motor cortices contralateral to the responding hands Motor preparation before action execution (Smulders and Miller, 2012) (Gorman Bozorgpour et al., 2013)
Late positive potential (LPP) Positive-going slow wave arising around 600 ms poststimulus Salience of emotional stimuli (Olofsson et al., 2008) (Althaus et al., 2015; Fan et al., 2014)



Error detection Error-related negativity (ERN) Negative-going wave rising 50–100 ms following erroneous response execution over frontocentral electrodes Unconscious error processing (Nieuwenhuis et al., 2001) (Michelini et al., 2016; O’Connell et al., 2009)
Error-related positivity (PE) Positive-going wave over centro-parietal electrodes peaking around 200-500 ms post-error, after the occurrence of ERN Conscious error processing (Wessel, 2012) (Michelini et al., 2016; O’Connell et al., 2009)

Note. ERP refers to transient time-locked EEG activity typically averaged across trials. Relevant quantitative measures include amplitude (in voltage, interpreted as engagement of a particular cognitive process) and latency (in ms, interpreted as timing of a particular cognitive process) (Kappenman and Luck, 2012).
