Note: Prenatal stress and adverse childhood experiences (ACEs) coded as 0 = low, 1 = high; sex coded as 1 = male, 2 = female; race coded as 0 = African American, 1 = white; gestational age reported in weeks. N = 167. AA = African American; PP1 = play period 1; PP2 = play period 2; RSA = respiratory sinus arrhythmia; SF = still face.
