The cognitive capacity of the human brain is its ability to process the sensory input information it receives primarily through visual and auditory perception, and secondarily from other sensory capabilities such as taste, touch and smell, and the mental energy required to do so.


Extraneous cognitive load refers to the extra load presented in the form of input which is irrelevant to the topic primarily being addressed in the learning process. Germane cognitive load is one which facilitates the learning by association or sequencing the sensory inputs into meaningful units for the learner. Why should designers focus on working memory? Designers should focus on the working memory because it is that part of the memory where the information is held for a few seconds and organized into rational structures, which if reinforced with germane cognition can lead to a permanent impression in the long term memory, the latter being permanent in nature (Atkinson & Shiffrin, 1968). Working memory cannot hold more than 4-7 units during an interval of time and the visual artist should be able to identify the best visual and auditory inputs, structured into chunks, to have the maximum cognitive effect. Moreover, it is the working memory faction of human cognition where the information processing takes place. The auditory and the visual channels also act in cohesion at this juncture for maximum impact (Pavio, 1990). ...
