Visualization training is when, for example, a person is preparing for a sport... so they create the sport action place and events in their mind. They can create all the situations possible of what could happen in the sport, and they find ways to overcome these situations. The person can also create different possibilities of the sport in their mind... To sum it all up, Visualization training is when a person can picture events, activities, and places all in there mind while not even having any real visual things around them. This can relate to photographic memory in a way, because both create a picture in the mind.
