Cognitive load

Cognitive Load (CL) or Cognitive Load Theory is the concept that information should be presented at a pace and level of difficulty that corresponds to the way the human brain processes information.

CL, according to Cognitive Load Theory, equates to the cognitive load that information causes in the human brain.

Meaning of Cognitive Load

CL plays an important role in research with. kificial Intelligence (AI) and is applicable to a wide range of instructional strategies for both machine learning and human cognition.

What is the composition of CL?

  • Intrinsic CL – difficulty of the aspect to be learned itself.
  • Extrinsic CL – nature and delivery of the task
  • Learning-related CL – effort required to understand the learning material.

When working memory is overloaded, it can slow down the learning process, cause confusion, and lead to frustration. In fact, cognitive overload is one reason why some older people find learning a new technology so frustrating. It is well known that aging reduces the efficiency of working memory.
Similarly, very young children are susceptible to cognitive overload because very little information is stored in long-term memory to provide new information with a frame of reference.
