    In about Time Perception by Edward Willett, the author talks about the foolwling test:Dr. Anthony Chaston and Dr. Alan Kingstone of the University of Alberta's Department of Psychology gave subjects tests that required them to find specific items in various images. Before they began, they were told that once the test was over, they would be asked to estimate how long it took. In the simplest of the seven different levels of test, the items sought were a different colour than everything else, or hardly hidden at all. In the more difficult levels, the items were placed among many similar-looking items--or weren't even present. It showed something that most people are familiar with:The harder the search task, the smaller the estimate of how long the test had taken. In other words, the more engaged the mind on a task, the faster time seems to go by.I have lost track of time while being immersed in some heavy thinking. But this is an interesting observation. Because if an application keeps on engaging a user's brain even during a refresh of a screen or retrieval of information, the perceived time spent waiting will be lower than the actual time spent. I experience that myself with AJAX -based Web applications where a lot of the retrieval is done in the background and the applications keep the user engaged. These application just feel a lot quicker and they probable are not. Another interesting quote:... because people are generally better at predicting how long a task will take than estimating how long it took.I think this is directly relevant to the whole response times issue. The moment that people complain about the response time is when their estimation/expectation is not met. Fascinating mix of psychology and technology. Roland Stens rstens@performancetester.com
