Advantages
🔵It is easier for the user to use a user interface that matches his/her mental model
🔵It takes less time for a user to learn how to use the interface.
🔵The interface is predictable for the user as it will match their requirements.
🔵The user will gain transferable skills so it will be easier to use other applications matching the mental model.
Disadvantages
🔴The range of definitions of what constitutes a mental model can cause confusion...
...possibly resulting in inaccurate results.
🔴There is a lack of a clear methodology in the use of mental models...
... often leading to bias as it is based on the designer’s own interpretation of what the user is thinking out loud.
🔴Different designers observing the same interaction may derive different mental models.
🔴There is little research about how to design to help the user create the best mental model.
🔴It can be difficult to match the user interface to a user's perception of the real world.
