Adoption-related curiosity was examined for a group of 169 emerging adults (M= 25.0 years) who were adopted as infants. The Adoption Communication Pathway model guided the research questions about formation of an information gap, which exists when there is a difference between what an adopted person knows and what he or she wants to know, and specific issues about which emerging adults were curious. Differences in these specific issues were examined across sex and contact with birth parents at adolescence. Logistic regression analyses revealed that the formation of an adoption information gap, which contains the content of curiosity, was more likely for those who less satisfied with the amount of contact in at both adolescence and emerging adulthood. Content of the information gap at emerging adulthood will be presented
