Dr. Aris investigated whether preschool children's sharing behaviour differed depending on the type of media they watched. He recruited participants using an opportunity sample at a local nursery.
He assigned one group of children to watch a 10-minute prosocial cartoon showing characters sharing toys (Condition A), and a different group of children to watch a 10-minute neutral educational cartoon about shapes (Condition B). Afterwards, he observed and recorded how many toys each child shared with a peer during a subsequent 15-minute free-play session.
Dr. Aris used an independent groups design in his investigation.
