Playdates: A Win-Win-Win Strategy for Recruitment of Infant Participants.

High-quality developmental science requires a reliable and representative stream of participants, yet recruiting infants at a satisfactory rate can be challenging. We recently developed a new recruitment technique: we invite parents to sign up for no-strings-attached playdates in our laboratory, where we provide toys, free coffee, and students to help entertain the children. We have consistently hosted 2-3 new parents per week via playdates.
