Event-related potentials (ERPs) can reflect the electrophysiological phenomena behind perception & attention. Often, certain time windows are applied for the analysis of ERP peaks (components). I cannot find any explicit justification in the literature why or how those time windows are chosen? E.g., P1 being the largest amplitude between 90 - 120ms. What factors should one consider when choosing time windows, and how ought this to be reported?
How do you form a rationale to justify choice of time windows in ERP analysis?
