Most of the following insights are taken from 100 Things Every Designer Needs to Know About People by Susan M. Weinschenk. This is a living note that I will update with my latest UX learnings.

How people see

• Peripheral vision v. central vision
• People are attracted to faces
• Differentiate one feature at a time
• People see cues and act on them
• People scan screens based on past experience and expectations
• How we perceive colors
• Titles and typography for better comprehension

How people remember

• Short-term memory is very limited
• From short-term to long-term memory
• Recognizing is easier than recalling
• How likely are people to remember a piece of information
• Memories degrade quickly over time

How people think

• Use more clicks and less thinking
• Cognitive > Visual > Motor loads (effort-wise)
• People are prone to mind wandering 30 percent of the time
