A developmental psychologist wants to investigate how different types of play-area flooring affect the cooperative behaviour of toddlers. She visits four local nurseries and, with permission, replaces the existing foam tiles in two of the nurseries with high-grip rubber mats (Condition AAA), while keeping the standard foam tiles in the other two nurseries (Condition BBB). She then observes and records the number of cooperative interactions during free play.
