Refers to processing in the human brain that forced the temporary work to keep pace with time and cause permanent memory. The important factors that increase cognitive load. The amount of information that must be remembered, too. In cognitive psychology, cognitive load is the load related to the executive control of working memory. Theories contend that during complex learning activities the amount of information and interactions that must be processed simultaneously can either under-load, or overload the finite amount of working memory one possesses. Instruction may be aimed at teaching learners problem solving skills, thinking and reasoning skills (including perception, memory, language, etc.).Many would agree that people learn better when they can build on what they already understand (known as existing schemas). Another aspect of cognitive load theory involves understanding how many discrete units of information can be retained in short-term memory before information loss occurs. An example of this principle that seems to be commonly cited is the use of 7-digit phone numbers, based on the theory that most people can only of information in their short-term memory. The cognitive load is much higher in the second instance because the brain must work to translate the language while simultaneously trying to understand the new information.
