Expertise reversal effect

The expertise reversal effect is related to cognitive load theories of learning. It states that guidance provided to experts can hinder their ability to learn: "learners would have to relate and reconcile the related components of available long-term memory base and externally provided guidance. Such integration processes may impose an additional working memory load and reduce resources available for learning new knowledge." The expertise reversal effect is a form of redundancy effect whereby added information places an additional load on working memory without providing any useful schema to direct executive function. The expertise reversal effect differs from the redundancy effect in that in the expertise reversal effect, "external information becomes redundant relative to a particular learner's internal knowledge structures," whereas in the redundancy effect, "only different external sources of information" are sources of cognitive load.
