Midloading follows the same rules as frontloading, but is done during the session. For some viewers, frontloading drives the imagination so badly that it is always destructive when given at the beginning of a session. So, with midloading, the monitor waits until the viewer has gotten good site contact and has actually begun perceiving the desired aspect of the target. At that time, the monitor provides the viewer with the midloading, letting him/her know that this is the aspect on which to focus for the rest of the session.
