 Children are randomly assigned to either an experimental group or to a treatment control group for 3 years. The experimental group focuses on relational issues; the control group focuses on cognitive development. Caregivers receiving the relational intervention are trained to provide nurturing care, and to help children learn to develop adequate regulatory skills. Caregivers in the treatment control group receive training designed to enhance childrens cognitive development. Caregivers in both groups will receive 10 home visits. Observations of children and parents are used to assess participants.
