Brain responses vary in duration-modeling strategies and challenges.

ABSTRACT: Typically, event-related brain responses are calculated invariant to the underlying event duration, even in cases where event durations observably vary: with reaction times, fixation durations, word lengths, or varying stimulus durations. Additionally, an often co-occurring consequence of differing event durations is a variable overlap of the responses to subsequent events. While the problem of overlap, for example, in fMRI and EEG is successfully addressed using linear overlap correction, it is unclear whether overlap correction and duration covariate modeling can be jointly used, as both are dependent on the same inter-event distance variability. Here, we first show that failing to explicitly account for event durations can lead to spurious results and thus are important to consider. Nex
