This project will develop and evaluate the initial effectiveness of an intervention training executive functioning, metacognition, and self-regulation in preschoolers attending certain high poverty Cincinnati preschools. Studies show that these skills are critical for school performance, and that children with better executive functioning have better long-term outcomes. It is also important to intervene early when children are most likely to profit because their brains are rapidly developing. There are some promising programs targeting these skills in preschoolers, but few are available to teachers for implementation in the classroom setting. The specific aims of this study are: 1) to adapt a promising clinic-based program for the preschool classroom environment, and 2) to test the feasibility and initial impact of the adapted program on executive functioning and school readiness in schools with a high proportion of children from low income families. The Principal Investigator is Dr. Leanne Tamm at Cincinnati Children’s Hospital Medical Center.
