AND human factors engineers. It is also known as
How can products be made more effective for human use - considering the predisposition to error humans have? Product development, usability testing, safety testing, and marketing research are now based in

In most textbooks, there is a picture of a stove to describe this type of psyc
hology. An older stove-top like the one pictured left is counterintuitive: That is, the controls for the
burners don't typically match where we think they should go. Turning the first knob, for example, does not necessarily turn on the first burner.
HUMAN EXPECTATIONS do not always match results.
Manufacturers believed consumers would turn to the manual to learn which knob is which, but this is unrealistic in a kitchen.
