Within ACL 3.0, the internal organisation of the person's brain uses a sense of direction and linear information to guide the person's behaviour. The addition of linear information seems to create a more cohesive sense of identity. The most obvious example is that they can usually tell you their name when you ask them.
With an improved sense of who they are, they seem to separate themselves from external objects. When asked, "What is this," they can name the object. When told to hold this towel, they can do it and give you eye contact, indicating that they know what you are talking about.
Their ability to use words is usually very limited and inconsistent. They are often described as being non-verbal when they have always had a cognitive disability.
