The user’s mental model is what they believe to be true.  According to our book, it is generally based on the user’s experiences, and how they assimilate new things into their existing knowledge.  Although the users believe to be true, their perception is not necessarily the truth.  Their perception is only based on their feelings and their experience.  The users tend to think whatever works and fulfills their goal whether it is true or not. 

 

This mental model strongly contrast with the implementation model of the programmers because the programmers are thinking about how the actual programming works.  They are thinking about how to program so they know how it exactly works.  The programmers do not know about individual user’s mental model and the uses do not know how the actual programming works.  They only focus on what it is important to them.
