Unit 9: People Make Mistakes

This chapter was very short but emphasized to the why, how and what of people making mistakes. Of particular note - at least to me - was the age statements: "older adults complete tasks differently than younger adults." "Kang and Yoon found no difference in completion rates for tasks due to age, but older adults... used different strategies than younger adults." In addition, the type of errors, errors under duress, predictable types of errors and not all mistakes are bad, are especially useful tools of information that web developers and designers should keep in mind when creating forms and event sequences. Understanding the intended audience and designing for them is a key component to successful engagement.
