ESSAY #1
Describe the human information processing model that we discussed in the class. Why is this
considered a functional rather than a purely structural system model? Explain what are the
system boundaries, inputs, outputs, and transformations involved in the human information
processing system. Provide a graphical representation to support your explanation.
