Cognitive Science: What makes your users tick

Like many usability consultants I have spent hours locked in rooms with strangers saying: “What do you think about this web page?” It is boring way to earn a living especially as you often know the answers and could tell clients without asking the questions.

Alas, most clients only believe opinions about their websites when it comes from random users - not you, the expert. Luckily the industry takes Jakob Nielson’s advice on testing: five users only to establish a pattern of responses (and because it’s cheap). Although, if we were really serious, we would need 30 users to talk about the statistical significance of our results.

Some of this boredom could be avoided (and client money saved) if everyone employed the patterns which already exist in users’ heads to create more intuitive webpages and GUIs. Cognitive science, the study of mind and intelligence, enables us to understand what makes our users tick. (more…)

A structural engineer once told me that he would always win pictionary if he was teamed with another engineer. Structural engineers have a symbolic language of their own and use it, normally in the workplace, to communicate more accurately. To the onlooker it is all triangles, little circles and arrows. But to the trained eye they represent bridge spans with fixed supports under uniform loads. Similarly, electrical engineers use seemingly incomprehensible symbols to describe apparatus layout. (more…)
