Imaginative play may help solve some behavioral problems
Researchers say unstructured play helps children learn to control their own emotions and behavior -- abilities that are a better predictor of a child's academic success than IQ. The regulated play many modern children experience doesn't foster such skills because the control has shifted to adults, which is something several researchers suspect may be behind the rising number of ADHD diagnoses.
