 Scanning refers to the process of items presented one after the other, in the same patterns, until a choice is made as the desired item is reached.Items can be presented either visually, by pointing, or auditorily, by speaking.Efficiency may be increased in visual partner scanning by the partner first pointing to groups of items, such as rows of letters, and once a row has been selected, proceeding to point to all letters in that row until a choice is made.
