Inter-individual differences in resting-state functional connectivity are linked to interval timing in irregular contexts
Behavioral evidence suggests that different mechanisms mediate duration perception depending on whether regular or irregular cues for time estimation are provided, and that individual differences in interoceptive processing may affect duration perception only in the latter case. However, no study has addressed brain correlates of this proposed distinction. Here participants performed a duration reproduction task in two conditions: with unevenly spaced stimuli during time estimation/reproduction (irregular), with regu- larly spaced stimuli provided during the same task (regular).
