B.F. Skinner

1904 - 1990

His work was done at Harvard University

Born in Susquehanna, Pennsylvania

Skinner's theories were cognitive, and believed that a system of rewards and punishments affects a child's behavior. To encourage a child to have good behavior, the parent/caregiver should give smiles, praises, or treats. If you want to stop bad behavior, none of these rewards should be given.

Nancy studied how each child scored on tests of mental and motor skills over time. The scores were based on gender, birth order, race, and education from parents. The results demonstrate the affects of attention and stimulation during infancy.
