purpose of this module is to introduce some of the basics of cognitive
science that apply to Human Factors design. The field of cognitive
psychology is one of the most interesting and most complex aspects

acquisition of knowledge but also to the processes by which sensory
information is attended to, transformed, stored, revised, retrieved,
and used. This module will address cognition by describing the role
of attention, perception, memory, and decision-making.
