What is automaticity?

According to www.dictionary.com

automaticity operates with minimal human intervention. Yet the word automatic, which goes back to the Greek word automatos, "acting of one's own will, self-acting, of itself," made up of two parts, auto-, "self," and -matos, "willing," is first recorded in English in 1748 with reference to motions of the body, such as the peristaltic action of the intestines: "The Motions are called automatic from their Resemblance to the Motions of Automata, or Machines, whose Principle of Motion is within themselves." Although the writer had machines in mind, automatic could be used of living things, a use we still have. The association of automatic chiefly with machinery may represent one instance of many in which we have come to see the world in mechanical terms.

Automaticityin a educational sense refers to the ability to use many different mental procedures at the one time, also automatically without any given drain on resources. For instance, to be able to identify, classify, understand, devlop ideas, draw inferences, and relate to the text while you are reading.
