SARA: Another characteristic of CVI is visually guided reach. In the introduction, we talked about the brain and the temporal lobe recognizing objects, and the parietal lobe allowing you to act on those objects. That is the integration of the dorsal or the "where" stream and the ventral, which is the "what" stream. When these two parts of the brain don't communicate or the communication is interrupted, then these two events can't happen at the same time. This may result in an individual who is not able to reach for and grasp an object while they are looking at it. This is sometimes referred to as look, look away, touch.
LYNNE: You will see two video examples. The first student looks and looks away before moving his hand to reach. The second student looks and reaches for the item, then looks away right as she touches the item to pick it up. The second example is subtle and may be easily missed. It illustrates a higher level of visual functioning.
