Brands
Brands are a shortcut. If someone had a positive experience with a brand in the past, then that brand is a signal of safety to the brain.

When designing for a touch devise, rethink hover
Selective Attention
People will pay attention to only one thing and ignore everything else as long as you give them specific instructions to do so, and the task doesn't take too long.
A person's unconscious constantly scans the environment for certain things, including their own name and messages about food, sex, and danger
Automaticitiy
If people perform a series of steps over and over again, the action will become automatic.
If you require people to perform a sequence repeatedly, make it easy to do, but realize that the trade-off is that people may make errors because they no longer are paying attention
Make it easy for people to undo not only their last action, but also an entire sequence
Rather than requiring people to perform a task over and over, consider a design where they can choose all the items they want to take action on and then perform the action on all the items at once.
Satisficing
Assume that people will get things done with the least amount of work possible. That may not always be the cause, but it's true more often than not.
People will satisfice - look for the good-enough solution rather than the optimal solution. Design with this in mind.
Text & Information
Reading Comprehension
What people understand and remember from a reading depends on their previous experiences, POV while reading, and instructions given before the reading
-
-
Memory & Schema
If you want people to remember something, then you have to go over it again and again. Practice makes perfect.
One of the major reasons to do user or customer research is so that you can identify and understand the schemata that your particular target audience has
New info is easier for to learn and remember the information if ti can fit it into an existing schema.
Provide Examples
People learn best by example. Don't just TELL people, SHOW them.
-
-
Shortcuts & Defaults
Provide shortcuts as long as they are easy to learn, find, and use. Don't assume that people will always use them.
Provide defaults if you know what most people will want to do most of the time, and if the result of choosing a default by mistake does not cause costly errors.
User Mistakes & Errors
Think ahead of what the likely mistakes will be. Change the design before it goes out so those mistakes won't be made.
Create a prototype of your design and have people test it. Make sure the testers are the same people as those who will use it.
-
Types of Errors
-
During testing/observation, collect data on which category of errors people are making.
Performance error types = (1) Commission (took additional, unnecessary steps), (2) Omission (omitted a step), (3) Wrong-Action (took the wrong action)
-
If in a field where are are not just annoying or inefficient, but actually may result in accidents or loss of lives, then you should use a system like HFACS to analyze and prevent errors.
Tone
Use easy and every-day conversational language. Short sentences, less complicated words, active voice, coherent flow.
Make it "scannable"
-
Use bullet points, line breaks, short paragraphs, white space
Document Layout
Line Length
-
Longer line lengths are easier to read because they interfere less with the flow of saccades and fixations
-
-
-
For a multi-page article, consider using multiple columns and a short line length (45 characters per line)
