There are three cognitive loads that impact the efficient formation of schemas. Extraneous cognitive load are those not directly required to master a task and have a negative impact on schema formation, reducing these is desirable and can be achieved through efficient design. Intrinsic cognitive load is that which is inherent in the task and for the most part cannot be reduced. Tasks with high intrinsic cognitive load are by nature more complex for an individual and in the long term are managed through equally complex schema. Germane cognitive load refers to the mental resources devoted to the efficient formation of schemas and is seen to have a positive effect on learning. Understanding these things will allow us to more effectively target our efforts as learners and teachers ensuring the cognitive load theory has a valuable role to play.
