Prior reproductive experience, or parity, may contribute to differential neural responses to infant stimuli during pregnancy. We examined the P300 elicited by viewing infant and adult faces, as well as houses, in women pregnant with their first child and compared their neural responses to women who had at least one child prior to their current pregnancy. We found the P300 amplitude was larger in women pregnant with their first child as compared to pregnant women who had previously had children. This larger P300 was observed in response to all visual stimuli and was not specific to infant faces. Taken together, these findings indicate increased sensitivity toward social and non-social stimuli in pregnancy and indicate the importance of measuring parity in social neuroscience studies of pregnancy and motherhood.
