Role of Elaboration in Retention of Information

This line of research provides support for the position that elaborations, when generated by the learner, facilitate learning and retention; however, author provided elaborations, unless very well crafted, actually are detrimental to the retention/retrieval of the main points of the document or the information to be learned.
