Dr. Alistair investigated whether five-year-old children's capacity for delayed gratification differed based on the environmental distractors present. He recruited participants using self-selected sampling from a local primary school.
Dr. Alistair placed one group of children in a room with high-sensory distractors (spinning lights and musical toys) (Condition A), and another group of children in a room with low-sensory distractors (a single coloring book and crayons) (Condition B). Each child was asked to wait for 10 minutes to receive a reward.
Dr. Alistair used an independent groups design in his investigation.
