Children with attention deficits concentrate better after walk in the park.

Objective: In the general population, attention is reliably enhanced after exposure to certain physical environments, particularly natural environments. This study examined the impacts of environments on attention in children with ADHD.

Method: In this within subjects design, each participant experienced each of three treatments (environments) in single blind controlled trials.

A potential natural treatment for attention-deficit/hyperactivity disorder: evidence from a national study.

Objectives: We examined the impact of relatively "green" or natural settings on attention-deficit/hyperactivity disorder (ADHD) symptoms across diverse subpopulations of children.

Methods: Parents nationwide rated the aftereffects of 49 common after-school and weekend activities on children's symptoms. Aftereffects were compared for activities conducted in green outdoor settings versus those conducted in both built outdoor and indoor settings.
