The ontogeny of exploratory behavior in the house rat ( Rattus rattus): The mobility gradient
Abstract Infants of rats and other mammals respond to a novel environment by becoming immobile, and then showing a process of motorial expansion called “warm‐up.” Starting from immobility, new types of movement are incorporated into the stream of behavior according to rather strict rules of order.
