What does the term ‘cognitive load’ refer to?

The term ‘cognitive load’ refers to the working memory resources needed to process information. Cognitive load theory suggests that our working memory has a limited capacity when it comes to processing new information. When cognitive load is high, it can lead to difficulties in learning and problem-solving because there are not enough resources in working memory to adequately manage all the active tasks and information.

This concept is particularly important in educational contexts, where understanding how to manage cognitive load can enhance the learning experience. Reducing unnecessary cognitive load allows learners to focus more effectively on the essential information and strategies required for mastery of a subject. In contrast, the other choices relate to different cognitive concepts, such as the total knowledge one may possess, the capacity and functioning of long-term memory, or the speed of cognitive tasks, which do not specifically encapsulate the essence of cognitive load.
