To solicit the participation of children, posters were hung outside of the MIT pre-schools and near the MIT Medical Center, pediatrics office. Additionally, email announcements were circulated, and the majority of children who participated in this study heard about it through word of mouth. Two subjects were studied in California, and the rest at the MIT Media Lab, in Cambridge Massachusetts. The majority of accompanying parents were the child's mother, but there were several other relations as well. I had hoped to attract at least one father to the study, but only managed to get two boy subjects instead of the six I had intended. Finally, the children who were attracted to this study all had extensive prior exposure to the Disney Tigger character.
