Are you a new mother of an infant who is 6 months old or younger? Moms and infants are needed for a study that explores brain and behavioral development in early life. The study takes place in the Psychology Department at Stanford University. You would participate in interviews, have a parent-child interaction in the laboratory, and have a scan taken of your baby's brain. Involvement in the study requires a time-commitment of up to 10 hours over the course of one to four visits. We will schedule the sessions around your availability (daytime, evenings, or weekends are all fine). Eligible mother-infant pairs will receive $25/hour for their time.
