One hundred and three children and adults participated in this study. Child participants were recruited from a mid-sized city in the South Eastern United States, and adult participants were either university students or community volunteers. Fourteen participants were excluded from data analyses for reasons explained in Supplemental Methods. The final sample consisted of twenty-nine 7- to 9-year-olds (Mage=8.37, SD = 0.84; 17 females and 12 males), twenty-nine 10- to 12-year-olds (Mage=11.55, SD = 0.91; 14 females and 15 males), and 31 young adults (Mage=21.80, SD = 3.21; 16 females and 15 males). All participants provided informed consent, which included written parental consent, children’s verbal or written assent, and written consent for adults. Each participant took part in one session that was approximately 2 h in length, including breaks. Families of child participants received monetary compensation ($10), and adults either received course credit or monetary compensation ($10).
