The human brain can only process a small amount of new information at once, but it can process very large amounts of stored information. With extensive practice, information can be automatically recalled from long-term memory with minimal conscious effort.

They found that the format of instructional materials either promoted or limited learning.
This unnecessary cognitive load is described as extraneous. This is because it does not unduly load the learner with unnecessary information. Examples of alternative instructional materials include what are known as worked-examples and goal-free problems. Journal of Structural Learning.
The term was first used in the early s by Chandler and Sweller. As cognitive load increases, the sway in center of mass in elderly individuals increases. With increased distractions, particularly from cell phone use, students are more prone to experiencing high cognitive load which can reduce academic success. The latter requires intensive pre-training. It has been theorized that an impoverished environment can contribute to cognitive load.
