**Thoughts on Visual vs Tactual Perception**

- Visual impairment is not an isolated condition; it affects the whole process of information-gathering.
- Vision enables a person to simultaneously perceive all parts of an object in its totality and in its relationship to other objects.
- The visually impaired learner has to rely on sequential observations (only part of an object can be seen or felt at a time) and the entire image has to be "built-up" out of the components. Relationships with other objects can be lost entirely.
- The level of cognition needed for integration of sequential information is higher than that needed for concept formation through immediate visual perception.
- If you have vision, you can experience this way of processing information by looking at a drawing through a very small hole in a piece of card held over the drawing; I think that you will find that it's hard for you to "get the picture.
