dogs, church bells, a person talking, or subway turnstiles 
(to name a few) is essential to effi cient travel. Underlying 
use of this localization ability is a list of spatial concepts 
(i.e., right, left, up, down, forward, etc.) that a person 
must have internalized and be able to use to connect his 
or her own position to the sound. Being able to connect 
your own position to another object in spatial terms is 
the fi rst step to purposeful movement. One of the early 
milestones of purposeful movement for an infant is reaching 
toward a sound producing toy. Recognizing that the toy 
is in a particular place and that the infant can move to 
reach that toy begins the process of movement through 
the environment and a lifetime of interaction with sounds 
in the environment. As an infant toddles, a parent’s voice 
becomes a common stationary sound the infant moves 
toward. It is partially because we spend so much of our early 
development moving toward meaningful sounds that we are 
better able to localize sounds directly in front of us.
Moving from activities in which discrete sounds are 
stationary and a child begins to move in relation to them 
assists in the development of self-to-object concepts. 
Learning how a sound’s position changes in relation 
to a child’s body as he or she moves about is one way 
to approach the instruction of this concept. As more 
sounds become important to the child, object-to-object 
relationships begin to be developed. However, these
spatial relations are better developed if a child has ongoing, 
active exploration of the sound producing objects and their 
relative positions.
Chapter 5 dealt with situations in which both the learner 
and the sound could be in motion. A number of important 
daily O&M tasks correspond to this category. As a toddler 
begins walking or crawling through the home environment, 
sounds such as the family dog or siblings move around 
the environment. These are the fi rst consistent exposures 
to sounds that move around the infant at a time when 
the infant is also able to make large body movements in 
reaction. Play with a parent or sibling that involves running 
to or away helps calibrate the auditory system. A parent 
rolling a toy car or truck toward a child who then reaches 
for it, a child running away from a family member playfully 
chasing them, or a child following a dog to pet it are all early 
examples of localizing and moving in reaction to moving 
sound sources. The activities in this manual take this kind of 
exposure and systemize it so that a child is made aware of 
the kind of information they have been reacting to and how 
to become more adept at doing so. This practice can be 
applied to future O&M tasks.
The following are examples of daily tasks applicable for some 
of the activities outlined in chapter 5:
Activity One: Tracking a sound source by moving only 
the head
  1.   Tracking a person as they walk. A common example 
of this task indoors is paying attention to a teacher 
walking in a classroom. If a teacher (or anybody) is 
talking to the child while simultaneously walking, it
