Cognitive engineering is a method of study usingcognitive psychology andcognitive neuroscience to design and develop engineering systems to support or improve the cognitive processes of users.[1]
It was an engineering method used in the 1970s atBell Labs, focused on how people form acognitive model of a system based upon common metaphors.[2] As explained, byJoseph Henry Condon:[2]
"The idea is that people form a model. You present them with some instruments, tools, like a faucet, electric stove or something like that and demonstrate how it works. They then form in their heads a model that shows how it works inside to help them remember how to use it in the future. It may be a totally erroneous model of what is going on inside the black box."

According to Condon, the ideas of cognitive engineering were developed later than, and independent from, the early work on theUnix operating system.[3]
Don Norman cited principles of cognitive engineering in his 1981 article, "The truth about Unix: The user interface is horrid." Norman criticized theuser interface of Unix as being "a disaster for the casual user."[4] However the "casual user" is not the target audience for UNIX and as the Condon quote above indicates, a high level of user interface abstraction leads to cognitive models that may be "totally erroneous."[fact or opinion?]
