When a user lands on a site, they have certain expectations for where elements like the search
Cuando un usuario llega a un sitio, tiene ciertas expectativas de dónde elementos como la barra de búsqueda
function might be located, what steps they might need to follow to accomplish their goal,
puede estar localizado, qué pasos podría seguir para lograr su tarea,
or what would happen if they clicked on something.
o qué pasaría si hiciera clic en algo.
We refer to these expectations as their mental model.
Nos referimos a estas expectativas como su modelo mental.
A mental model is what the user believes about a system, such as your website.
Un modelo mental es lo que el usuario cree acerca de un sistema, como tu sitio web.
This model isn't based on facts, but is instead constructed primarily on the person's past
Este modelo no se basa en hechos, sino que es construido principalmente sobre las experiencias pasadas
experiences and what they *think* they know about the system.
de la persona y lo que ellos *piensan* que saben sobre el sistema.
These beliefs affect the way we need to design because people base their actions according
Estas creencias afectan la forma en que necesitamos diseñar porque las personas basan sus acciones de acuerdo
to their mental model.
a su modelo mental.
So when the system doesn't work the way people expect, they get confused.
Así que cuando el sistema no funciona como la gente espera, se confunden.
For example, a really common mismatch I've seen in usability testing revolves around
Por ejemplo, un desajuste muy común que he visto en pruebas de usabilidad gira en torno al
people's mental model for the browser back button.
modelo mental de las personas con el botón de retroceso del navegador.
People believe that the back button will always take them just one step back, to the previous
La gente cree que el botón de retroceso siempre va a darles un paso atrás, al estado
state of the system.
anterior del sistema.
That's their mental model.
Ese es su modelo mental.
Unfortunately, this doesn't always work as they expect.
Desafortunadamente, esto no siempre funciona como esperan.
Sometimes, people hit the browser back button to get back to the page after a modal window
A veces, la gente pulsa el botón de retroceso del navegador para volver a la página después de que una ventana modal
has opened.
se ha abierto.
But because the modal window wasn't a new URL, they end up being taken back off that
Pero porque la ventana modal no era una nueva URL, terminan siendo retirados de esa
page entirely; which, to them, seems like two steps back.
página entera lo cual, para ellos, parece dos pasos hacia atrás.
Or maybe a page was opened in a new tab, which they didn't notice, and suddenly the back
O tal vez se abrió una página en una nueva pestaña, que no se dieron cuenta, y de repente el botón atrás
button isn't available at all.
no está disponible en absoluto.
So when a mismatch in the user's mental model and the system occurs, it can be really difficult
Así que cuando se produce un desajuste entre el modelo mental del usuario y el sistema, puede ser realmente difícil
for people to recover or to understand what to do.
que la gente se recupere o entienda lo que tiene que hacer.
And even when people can understand what happens, it often makes them feel bad for making that
E incluso cuando la gente pueda entender lo que sucede, a menudo se sienten mal por hacer ese
mistake, or it might seem like your site is broken.
error, o puede parecer que tu sitio esta roto.
And that lowers their perceived value of the site.
Y eso baja el valor percibido del sitio.
Respecting people's mental model is really the foundation of designing usable, user-centered systems.
Respetar el modelo mental de las personas es realmente la fundación para diseñar sistemas usables, centrados en el usuario.
It's important to conduct research and find out what our users' mental models are to make sure
Es importante realizar una investigación y descubrir cuáles son los modelos mentales de nuestros usuarios para asegurarse
we design the system to match those expectations.
de que diseñamos el sistema para satisfacer esas expectativas.
