What is Visual Tracking
Visual reception, visual processing and visual discrimination are used synonymously with visual perception by many authors. The brain "perceives" what the eyes see. The images are sent along neural pathways for interpretation. Perception includes the act of becoming meaningfully aware and affectively appreciative of a stimulus. In this section we are concerned with the perception of visual stimuli.
Among the more frequently noticed inefficiencies in visual perception is poor figure-ground analysis, a problem in separating out meaningless visual background from important visual foreground data. Difficulty in judging distance is a visual discrimination or visual perception problem. Another frequently documented visual perception problem is visual closure, difficulty in perceiving readily the elements that go into the completion of the percept. Students with visual closure problems often lose the ends of words they read. Rotation of shapes (as in the confusion of b and d and reading saw for was) is an aspect of confused visual input. These problems are so specialized they are dealt with in a separate section (see Reversals).
We suggest modifications to the environment for individuals who fail to perceive significant portions of the total collection of visual information available. The student with visual receptive difficulty might miss punctuation in reading and operational signs in math. Dollar signs and decimal points get overlooked. Sometimes students with visual perception problems miss whole segments of work on a page. Teachers often return papers with the comment "careless errors" written on them. Standardized tests that require one to blacken a specific box to designate an answer are especially difficult, even when one knows the answer. These STRATEGIES are designed to improve daily efficiency, not to improve the individual's visual perception.
Identifying Visual Tracking Issues
Students with problems in this area have trouble with those pages in the magazines found in waiting rooms that provide a busy picture with hidden details. They will lose their own things easily. This is especially true in an environment that is cluttered. They miss visual details. It is as if their computer fails to pick up the full collection of visual information from the total collection of information available.
This is an input disorder.
If this problem co-exists with inefficiency with sequential order, we can expect disorganization to be a problem. The depth of the visual receptive difficulty and the depth of the sequential order problem seem to be very relevant to the degree of disorganization that will develop.
