Usability link

I came across a good link to an article that proved to be very interesting reading. It was in regard to usability testing and the way in which a little psychology can make it a more valuable and intuitive experience. It may be more than is necessary to know for fulfilling a Unit requirement, but it is interesting all the same. I prefer total honesty over some type of psychological manipulation...but that is just me... some of the ideas do make sense however... here is the link... http://www.uxmatters.com/MT/archives/000183.php
