Examined relationship between visual organization, perceptual closure, and compulsive-like behaviors in 3- to 6-year-olds. Found that children's performance on visual organization and perceptual-closure tasks were significantly related to compulsive-like behaviors reported by parents, and these associations were mediated by mental age. Results further validate the Childhood Routines Inventory and highlight sensory/perceptual components of normative compulsive-like behavior in young children. (Author/KB)
