Linear information is used in ACL 3 High to help the person organise what they are doing. The concept of a line becomes much stronger and the person can trace the outline of shapes and colour within a line within ACL 3.6. Within ACL 3.8, the person has enough mental energy to keep filling all the empty spaces or use all objects until they are done. The outline of shapes captures the person's attention. This information is strong as the person still lacks true classification ability where grouping of information takes priority.
