aging cohort may be of utility. At the other end of the lifecourse, as offspring of COGA members attain child‐bearing age, opportunities to address questions related to intergenerational transmission of behavioral, genetic/epigenetic and brain‐related liability arise. 7 While current studies of childhood and even neonatal development in the context of familial risk do exist, gathering data on the next generation of COGA bears the advantage of framing questions regarding early development against a wealth of longitudinal familial data, which are one of few data patterns that allow nature to be disentangled from the impact of nurture.
