molestation by relative or non-relative). Importantly, age at occurrence of each event was recorded, and this information was used in the present study. We focused on traumatic events occurring before 10 years of age, given the suggestion that trauma exposure at early stages of development might be more influential than later exposures for neurobiological development and onset of later psychopathology23,64,65 and our desire to measure events that preceded measurement of neurophysiologic and behavioral outcomes. Any trauma experienced after 10 years was combined into a binary measure that was used as a covariate in all models, because trauma exposure is known to re-occur throughout the lifecourse.66
