For Aim 2, 600 preschool children will be recruited from up to 20 schools in Harlem, NY, and perform a 2:1 (2 intervention: 1 control) cluster randomization of the schools. The preschool children, their teachers and their parent/caregivers will receive our intensive educational program for a period of up to five months. The primary assessments mentioned in Aim 2 will occur at five months. At that time, the control schools will crossover to receive the educational program over the next five months.
