What is Sources of Cognitive Load

Chapter 41
Handbook of Research on Effective Electronic Gaming in Education
Features of external information structures or cognitive characteristics of individual users that determine required working memory resources. Intrinsic cognitive load is caused by levels of interactivity between elements of information that need to be processed simultaneously. Extraneous cognitive load is imposed by the design of information presentations (e.g., separated in space- and/or time-related elements; an excessive step-size or rate of introducing new elements of information; limited user knowledge that is not compensated by provided support; user knowledge base that overlaps with provided external guidance).

Abstract
This chapter provides an overview of our cognitive architecture and its implications for the design of game-based learning environments. Design of educational technologies should take into account how the human mind works and what its cognitive limitations are. Processing limitations of working memory, which becomes overloaded if more than a few chunks of information are processed simultaneously, represent a major factor influencing the effectiveness of learning in educational games. The chapter describes different types and sources of cognitive load and the specific demands of games on cognitive resources. It outlines information presentation design methods for dealing with potential cognitive overload, and presents some techniques (subjective rating scales, dual-task techniques, and concurrent verbal protocols) that could be used for evaluating cognitive load in electronic gaming in education.
