The nurse is teaching the mother of a newborn to develop her baby's sensory system. to further improve the infant's most developed sense, the nurse instructed the mother to do stroke the newborn's cheek with her nipple to direct the baby's mouth to nipple.
What is a Sensory system?
Sensory systems pick up inputs like light and sound waves and translate them into neural signals that the nervous system can understand. Some sensory systems also pick up internal impulses, such as input regarding limb position sent by proprioceptors found in muscles and tendons, in addition to exterior stimuli picked up by the senses. There are receptor cells in every sensory system that are trained to recognize a certain kind of signals. In the inner ear, for example, hair cells have cilia that move in response to sound waves, and in the nasal cavity, olfactory receptor neurons have receptors that attach to odorant molecules.

In the pillbug experiment, if the pillbugs in the experimental chamber would have moved to the side of the chamber with sand instead of cornstarch then the Pillbugs tend to prefer sand over cornstarch.
Pillbugs are categorised as terrestrial isopods and are in the crustacea family. The purpose of this experiment is to determine if pillbugs, often known as roly-polys, prefer light or darkness. They are cold-blooded, slow-moving organisms whose environs control their body temperatures.
The pill bugs are the controlled variable, and the behaviour of the pillbug is the dependent variable. The experimental group is housed in a moist environment with water and cornstarch, whereas the control group is in a dry environment with sand.
