Auditory Perception How they respond! This 20-lesson unit is designed to help teachers evaluate students' ability to understand and appropriately respond to verbal information. The exercises may also be used to assist in the development of listening and following direction skills. "How would you feel if a bull was chasing you?" "Is a potato a fruit?" "Wink your eye!" For those students who find verbal response difficult, or to add an element of fun, picture response cards have been included.
